In the context of IATF 16949, “Design and Development Output” refers to a crucial phase in the automotive product development process. It encompasses all the tangible results and documentation generated during the design and development of new automotive products or processes. This phase plays a pivotal role in ensuring that the final product meets the required quality standards and customer expectations. During the design and development output phase, various activities take place, including product design, engineering analyses, prototype development, testing, and validation. The outputs generated during this process can include engineering specifications, CAD drawings, technical documentation, validation test results, risk assessments, and any other relevant data related to the product’s development. One of the key objectives of the design and development output phase is to establish clear and concise documentation that enables effective communication and collaboration between different teams and stakeholders involved in the product development process. This documentation serves as a reference for manufacturing, quality control, and post-production support, ensuring that all parties have a shared understanding of the product’s requirements and specifications. Additionally, the IATF 16949 standard places a strong emphasis on risk management during the design and development output phase. Companies are required to identify potential risks associated with the product or process and implement appropriate measures to mitigate or eliminate these risks. This risk-based approach helps prevent defects and potential failures, ultimately contributing to enhanced product quality and customer satisfaction. In summary, the design and development output in IATF 16949 refers to the tangible results and documentation generated during the automotive product development process. It involves various activities and outputs that are crucial for effective communication, risk management, and ensuring the final product meets the required quality standards and customer expectations within the automotive industry. Please note that it’s essential to refer to the latest version of the IATF standard and any updates beyond my last knowledge update to ensure accurate and up-to-date information.

Clause 8.3.5.1 Design and development outputs

In addition to the requirement given in ISO 9001:2015 Clause 8.3.5 Design and development output, Clause 8.3.5.1 mandates that the product design output needs to be presented in a way that aligns with and can be verified and validated against the product design input requirements. This output encompasses several components such as design risk analysis (FMEA), results from reliability studies, and specifications for product special characteristics. Additionally, the results of product design error prevention methods like DFSS, DFMA, and FTA should be incorporated into the product design output. Moreover, the product definition, including 3D models, technical data packages, product manufacturing information, and geometric dimensioning and tolerancing (GD&T), should be included. This encompasses 2D drawings as well as specifications for product manufacturing information and geometric dimensioning and tolerancing (GD&T). The product design review results, service diagnostic guidelines, and instructions for repair and serviceability also form part of the product design output. Furthermore, requirements for service parts, packaging, and labeling for shipping must be incorporated. Any ongoing engineering issues being resolved through a trade-off process should be included in interim design outputs.

The standard requires that the design output be documented and expressed in terms of requirements that can be verified and validated against design-input requirements. The design outputs are to be fully documented before the product is launched into production. Some organizations are eager to start producing product before the design is complete, particularly if it is marginally ahead of competitors’ designs. You need to be able to verify that both the design input requirements and user requirements (if different) have been achieved in the product so they need to be expressed in appropriate terms. The vehicle to contain such requirements is usually a product or service specification. You also need to be able to verify that the design output meets the design input and to achieve this you will need to document your calculations and analyses. In some industry sectors the design output contains all the specifications needed for manufacture, procure, inspect, test, install, operate, and maintain a product or service. In the automobile, electronics, and aerospace industries, prototyping and pre-production phases are an accepted and required stage through which new designs must pass. For the design output to be expressed in terms that can be verified and validated against design input requirements, the design input requirements need to require documentation of the output necessary in order to manufacture, procure, inspect, test, install, operate, and maintain a product or service. Product design and development output may be product or documentation or both. Product may be prototype or finished product and documentation could be in computerized or hardcopy form. A manufacturing design and development output may be a physical manufacturing process as well as documentation. Check product design and development output against the input requirements specified, before you use it any further. Express product design output in any or all the forms specified. Provide appropriate information to purchasing (material or service specifications); production (product specifications, special characteristics, drawings, FMEA’s, diagnostics, etc.); service (product specifications; performance reliability and maintenance criteria). Initially, this information may be used for trials and validation, before being firmed up. The product design output should result from a process that includes efforts to simplify, optimize, innovate and reduce waste. The design process should include

• Analysis of cost, performance and business risks and trade-offs
• Appropriate use of geometric dimensioning and tolerancing
• Design for assembly (DFA);
• Design for manufacturing (DFM);
• design of experiments (DOE);
• quality function deployment (QFD);
• Value engineering (VE)
• Tolerance studies and appropriate alternatives
• Use of Design FMEA’s
• Use of feedback from testing, production and the field

Product requirements.

Expressing the design output in terms that can be verified and validated means that the requirements for the product or service need to be defined and documented. The design input requirements should have been expressed in a way that would allow a number of possible solutions. The design output requirements should therefore be expressed as all the inherent features and characteristics of the design that reflect a product which will satisfy these requirements. Hence it should fulfill the stated or implied needs, i.e. be fit for purpose. Product specifications should specify requirements for the manufacture, assembly, and installation of the product in a manner that provides acceptance criteria for inspection and test. They may be written specifications, engineering drawings, diagrams, inspection and test specifications, and schematics. With complex products you may need a hierarchy of documents from system drawings showing the system installation to component drawings for piece—part manufacture. Where there are several documents that make up the product specification there should be an overall listing that relates documents to one another. Service specifications should provide a clear description of the manner in which the service is to be delivered, the criteria for its acceptability, the resources required, including the numbers and skills of the personnel required, the numbers and types of facilities and equipment necessary, and the interfaces with other services and suppliers. In addition to the documents that serve product manufacture and installation or service delivery, documents may also be required for maintenance and operation. The product descriptions, handbooks, operating manuals, user guides, and other documents which support the product or service in use are as much a part of the design as the other product requirements. Unlike the manufacturing data, the support documents may be published either generally or supplied with the product to the customer. The design of such documentation is critical to the success of the product, as poorly constructed hand- books can be detrimental to sales. The requirements within the product specification need to be expressed in terms that can be verified. Hence you should avoid subjective terms such as “good quality components”, “high reliability”, “commercial standard parts”, etc. as these requirements are not sufficiently definitive to be verified in a consistent manner.

Design calculations
Throughout the design process, calculations will need to be made to size components and determine characteristics and tolerances. These calculations should be recorded and retained together with the other design documentation but may not be issued. In performing design calculations it is important that the status of the design on which the calculations are based is recorded. When there are changes in the design these calculations may need to be repeated. The validity of the calculations should also be examined as part of the design verification activity. One method of recording calculations is in a designer’s log book which may contain all manner of things and so the calculations may not be readily retrievable when needed. Recording the calculations in separate reports or in separate files along with the computer data will improve retrieval. Design analyses Analyses are types of calculations but may be comparative studies, predictions, and estimations. Examples are stress analysis, reliability analysis, hazard analysis. Analyses are often performed to detect whether the design has any inherent modes of failure and to predict the probability of occurrence. The analyses assist in design improvement and the
prevention of failure, hazard, deterioration, and other adverse conditions. Analyses may need to be conducted as the end-use conditions may not be reproducible in the factory. Assumptions may need to be made about the interfaces, the environment, the actions of users, etc. and analysis of such conditions assists in determining characteristics as well as verifying the inherent characteristics.

Ensuring that design output meets design input requirements
The standard requires that the design output meets the design input requirements. The techniques of design verification can be used to verify that the design output meets the design input requirements. However, design verification is often an iterative process. As features are determined, their compliance with the requirements should be checked by calculation, analysis, or test on development models. Your development plan should identify the stages at which each requirement will be verified so as to give warning of noncompliance as early as possible.

Defining acceptance criteria
The standard requires that the design output contains or makes reference to acceptance criteria. Acceptance criteria are the requirements which, if met, will deem the product acceptable. Every requirement should be stated in such a way that it can be verified. Characteristics should be specified in measurable terms with tolerances or min/max limits. These limits should be such that will ensure that all production versions will perform to the product specification and that such limits are well within the limits to which the design has been tested . Where there are common standards for certain features, these may be contained in a standards manual. Where this method is used it is still necessary to reference the standards in the particular specifications to ensure that the producers are always given full instructions. Some organizations omit common standards from their specifications. This makes it difficult to specify different standards or to subcontract the manufacture of the product without handing over proprietary information.

Identifying crucial characteristics
The standard requires that the supplier identify those characteristics of the design that are crucial to the safe and proper functioning of the product. Certain characteristics will be critical to the safe operation of the product and these need to be identified in the design output documentation, especially in the maintenance and operating instructions. The additional note qualifies these characteristics as “special characteristics”, thereby establishing consistency with other documents and references. Drawings should indicate the warning notices required, where such notices should be placed and how they should be affixed. Red lines on tachometers indicate safe limits for engines, audible warnings on computers, on smoke alarms, low oil warning lights, etc. indicate improper function or potential danger. In some cases it may be necessary to mark dimensions or other characteristics on drawings to indicate that they are critical and employ special procedures for dealing with any variations. In passenger vehicle component design, certain parts are regarded as safety—critical because they carry load or need to behave in a certain manner under stress. Others are not critical because they carry virtually no load, so there can be a greater tolerance on deviations from specification.

Reviewing design output
The standard requires that the design output be reviewed before release. Design documents should have been through a vetting process prior to presentation for design review. The design output may consist of many documents, each of which fulfills a certain purpose. It is important that these documents are reviewed and verified as being fit for their purpose before release. By analyzing this data using statistical techniques the results assist in error removal and prevention. Design documentation reviews can be made effective by providing data requirements for each type of document as part of the design and development planning process. The data requirement can be used both as an input to the design process and as acceptance criteria for the design output documentation review. The data requirements would specify the input documents and the content and format required for the document in terms of an outline. Contracts with procurement agencies often specify deliverable documents and by invoking formal data requirements in the contract the customer is then assured of the outputs.

Design risk analysis (FMEA)

As per IATF 16949 requirements, the product design output should include Design Risk Analysis, specifically the use of Failure Mode and Effects Analysis (FMEA). FMEA is a crucial tool used during the product design process to systematically identify potential failure modes, assess their effects, and prioritize actions to prevent or mitigate risks. FMEA helps automotive companies proactively address and manage potential risks associated with the design and development of products. By conducting a thorough FMEA, teams can identify weaknesses and vulnerabilities in the design early in the development process, allowing them to implement appropriate design changes, controls, or improvements to enhance product quality and reliability. The FMEA process typically involves cross-functional teams that analyze each component, subsystem, or process step to identify potential failure modes and their corresponding effects on the overall performance of the product. For each identified failure mode, teams assign a risk priority number (RPN) based on the severity, occurrence, and detectability of the failure. Higher RPN values indicate higher risks, which require more attention and action. Through the FMEA process, automotive companies can focus their efforts on critical areas, where even small improvements can have a significant impact on product quality and customer satisfaction. Additionally, FMEA results can guide companies in setting priorities for design validation, testing, and verification activities. Overall, including Design Risk Analysis, such as FMEA, in the product design output is crucial to align with the requirements of IATF 16949 and to promote a robust and proactive approach to risk management during the product development process in the automotive industry.

Reliability study results

In the context of IATF 16949 and automotive product design, the product design output should include reliability study results. Reliability studies are an essential aspect of the product development process in the automotive industry, and their inclusion in the design output is crucial for ensuring high product quality and customer satisfaction.Reliability studies assess the product’s ability to perform its intended functions consistently and reliably over a specified period and under defined conditions. These studies involve subjecting the product to various tests, simulations, and analyses to evaluate its performance and identify potential areas of improvement.The primary objectives of reliability studies include:

1. Identifying Weak Points: Reliability studies help uncover potential weak points in the product’s design, materials, or manufacturing processes that could lead to failures or malfunctions during the product’s lifespan.
2. Predicting Product Lifespan: By subjecting the product to accelerated aging tests or real-world usage simulations, reliability studies can estimate the product’s expected lifespan and identify any components or systems that may require improvement to meet longevity targets.
3. Improving Product Quality: Insights gained from reliability studies are used to make design enhancements, select better materials, and implement improved manufacturing processes, all of which contribute to a higher-quality and more reliable product.
4. Meeting Customer Expectations: Ensuring product reliability aligns with customer expectations and enhances customer satisfaction, leading to greater brand loyalty and positive word-of-mouth.
5. Compliance with Regulatory Requirements: Reliability studies are often necessary to meet industry standards and regulatory requirements, especially in safety-critical applications like the automotive sector.

By including reliability study results in the product design output, automotive companies can demonstrate their commitment to producing high-quality and reliable products. These results provide valuable data for ongoing improvements, risk management, and decision-making throughout the product’s life cycle.It’s important to note that reliability studies should be conducted using appropriate methodologies and statistical techniques to yield reliable and meaningful results. By doing so, automotive companies can optimize the performance, safety, and longevity of their products, all of which contribute to the overall success of their business in a competitive market.

Interim design outputs during the product development process should include any engineering problems that have been identified and resolved through a trade-off process. As products are designed and developed, various engineering challenges and constraints may arise, requiring careful evaluation and decision-making to find the best possible solutions.The trade-off process involves considering different options, evaluating their advantages and disadvantages, and making informed decisions based on various factors such as performance, cost, manufacturability, safety, and customer requirements. It is common for design teams to encounter conflicting objectives that cannot all be fully satisfied simultaneously. In such cases, trade-offs are necessary to find an optimal balance and resolve the engineering problems effectively.Here are some key aspects of how the trade-off process contributes to interim design outputs:

1. Problem Identification: Interim design outputs document the engineering problems that have been identified during the design process. These issues may relate to functionality, performance, manufacturability, material selection, or compliance with regulations.
2. Alternative Solutions: Design teams typically brainstorm and propose multiple solutions to address the identified problems. Each solution may have its strengths and weaknesses, leading to trade-offs between different design options.
3. Evaluation Criteria: Criteria for evaluating alternative solutions should be well-defined and aligned with project goals. These criteria can include technical feasibility, cost, time-to-market, risk, and customer requirements.
4. Decision-Making: Based on the evaluation of alternative solutions, the design team makes informed decisions on the best course of action. The trade-off process helps identify the most suitable design direction to proceed with.
5. Documentation: The trade-off process and the decisions made should be clearly documented in interim design outputs. This documentation provides transparency and serves as a reference for future stages of the design process.
6. Continuous Improvement: The trade-off process is iterative, allowing the design team to continuously improve the design by considering feedback, lessons learned, and evolving project requirements.

By including engineering problems being resolved through a trade-off process in interim design outputs, the product development team can ensure that critical decisions are well-documented and based on a systematic evaluation of various factors. It allows stakeholders to understand the reasoning behind design choices and supports effective communication among team members. This iterative approach to problem-solving contributes to the development of a well-balanced and optimized product design that meets both technical and customer requirements.

The standard requires the supplier to comply with a product and process approval process recognized by the customer. The product approval process, or PPAP is intended to validate that products made from production materials, tools, and processes meet the customer’s engineering requirements and that the production process has the potential to produce product meeting these requirements during an actual production run at the quoted production rate. The process commences following design and process verification during which a production trial run using production—standard tooling, subcontractors, materials, etc. produces the information needed to make a submission for product approval. Until approval is granted, shipment of production product will not be authorized. If any of the processes change then a new submission is required. Shipment of parts produced to the modified specifications or from modified processes should not be authorized until customer approval is granted. When one considers the potential risk involved in assembling unapproved products into production vehicles, it is hardly surprising that the customers impose such stringent requirements. The process is similar in other industries but more refined and regulated in mass production where the risks are greater. The requirements for product approval are defined in the reference manuals. You may not need to prepare product approval submissions for all the parts you supply. The applicability of product approval process is affected by several factors so definitive solutions cannot be offered. The fundamental requirement is that if you supply product to the automotive customers you need a product approval process in place. If you have been supplying parts for some time without product approval then you should confirm with your customer that you may continue to do so. The documentation required varies but is likely to include the following:

• Production part submission warrant — a form that captures essential information about the part and contains a declaration about the samples represented by the warrant
• Appearance approval report — a form that captures essential information about the appearance characteristics of the part
• Design records, including specifications, drawings, and CAD/CAM math data
• Engineering change orders not yet incorporated into the design data but embodied in the part
• Dimensional results using a pro forma or a marked up print
• Test results
• Process flow diagrams
• Process FMEA
• Design FMEA where applicable
• Control plans
• Process capability study report
• Measurement systems analysis report

The data on which the product approval submission is based should be generated during the process verification phase.When we speak of design in IATF, we think of the APQP. For submission of data and document to customer, we extract them from APQP files But in practice, many organizations do not start with APQP, but will base on PPAP directly for planning and for warrant submission. It saves time, no redundant work, and all the data and rules for approval are given here. This is what the clause say, a method initiated by the customer. So you can safely use this method for product and project management. And there is no need to do both APQP and PPAP for the same project. For submission, we have to approve info (e.g. ECN, PPAP) etc from sub-suppliers, before onward submission to customer. You should have evidence of this.If customer does not specify a method, you can use an internally- defined method for PPAP, complying to the outputs specified in 8.3.5, 8.3.5.1, 8.3.5.2 as applicable.For project scheduling, use a Gantt Chart, and lay out your tasks according to sequence. Most importantly, your trial and mass production dates should be based on the master schedule, from the customer. Inputs from customer are usually drawings and technical specs, and PSW form. This is not sufficient however. You need to ask for master schedule, a PPAP list, and lessons learned, if the part is new to you.

Clause 8.3.4.4 Product approval process

The organization needs to create, execute, and sustain a process for product and manufacturing approval that aligns with the customer’s specifications. They must authorize externally sourced products and services as per ISO 9001:2015 clause 8.4.3, “Information for external providers,” before sending their part approval to the customer. If the customer requires it, the organization must obtain documented product approval before shipping. They should keep records of these approvals. Product approval should come after verifying the manufacturing process.

Use the customer provided or recognized process provided one exists, otherwise use the appropriate OEM PPAP reference manual. Make your suppliers use the same procedures or manual as you do. If supplier PPAP’s are done by your purchasing function that is located offsite, make sure that both the offsite purchasing process as well as the PPAP process is identified in your QMS processes. The standard requires the supplier to apply the product approval process to subcontractors. Your subcontractors may not need to supply product approval submissions for all parts they supply but there are situations where subcontractor product approval submissions
are required. For example, GM requires product approval of all commodities supplied by subcontractors to first tier suppliers. The standard does point out that suppliers are responsible for subcontracted material and services so if your submission relies on your subcontractors operating capable processes, you should be requesting a product approval submission from them.

Verification of changes
The supplier should verify that changes are validated including all subcontractor changes and, when required by the customer, additional verification/ identification requirements shall be met. Following product approval any change to the product or the processes producing it needs to be assessed for its impact on the conditions of product approval. You need close contact with your subcontractors because you need to capture any changes they make and perform an impact assessment. This can be difficult if you are using proprietary products. Your contract with your supplier needs to require the supplier to notify you of any changes in product or process. Quite minor changes may have significant effect on the product you supply to your customer. In some cases, suppliers may not accommodate your requirements, especially if the order value is small.

Notification of changes
All changes to be notified to customers which may require customer approval. Customer approval is likely when:

• Products are modified.
• A discrepancy on a previously submitted part has been corrected.
• Changes are made to the production process, materials, tooling, subcontractors, etc.
• Production has been inactive for 12 months or more.
• Shipment has been suspended due to quality problems.

The organization shall establish, implement, and maintain a product and manufacturing approval process conforming to requirements defined by the customer.

Establishing, implementing, and maintaining a product and manufacturing approval process conforming to customer requirements is crucial for ensuring product quality, consistency, and customer satisfaction. This process typically involves several steps and controls to ensure that the products meet the specified standards. Here are the key components of such a process:

1. Understanding Customer Requirements: The organization must thoroughly understand the specific requirements and expectations of the customer concerning the product. This includes product specifications, quality standards, delivery schedules, and any other relevant criteria.
2. Documentation and Standard Operating Procedures: Develop clear and comprehensive documentation that outlines the entire product and manufacturing approval process. This should include standard operating procedures (SOPs) for each step involved in the process.
3. Design and Development: If the product requires design and development, the organization should have a well-defined process for designing the product according to customer requirements and validating the design before moving forward.
4. Risk Assessment: Conduct a risk assessment to identify potential risks associated with the product and its manufacturing process. Implement measures to mitigate these risks effectively.
5. Supplier Evaluation and Control: If the organization relies on suppliers for components or materials, it should have a supplier evaluation and control process in place. This ensures that the suppliers meet the necessary standards and can consistently deliver materials of the required quality.
6. Prototype and Sample Approval: Before starting full-scale production, create prototypes or samples of the product for the customer’s review and approval. This step helps identify any potential issues early in the process.
7. Manufacturing Process Validation: Validate the manufacturing process to ensure it can consistently produce products that meet customer requirements. This may involve conducting process capability studies and performance qualification tests.
8. Product Inspection and Testing: Implement inspection and testing procedures to verify that each product meets the specified requirements. This includes in-process inspections and final product inspections.
9. Non-Conformance Management: Establish a system to manage non-conforming products or processes. This includes identifying, documenting, investigating, and taking corrective actions to prevent recurrence.
10. Continuous Improvement: Regularly review the product and manufacturing approval process to identify opportunities for improvement. Implement corrective and preventive actions as necessary to enhance the overall process.
11. Customer Feedback and Satisfaction: Gather customer feedback to measure customer satisfaction and use this input to drive further improvements in the product and manufacturing approval process.
12. Training and Competence: Ensure that employees involved in the product and manufacturing approval process are adequately trained and competent to perform their tasks effectively.

By following these steps and maintaining a robust product and manufacturing approval process, the organization can meet customer requirements, produce high-quality products, and build strong relationships with its customers.

Production part approval process

The Production Part Approval Process (PPAP) is a standardized method used in the automotive and other manufacturing industries to ensure that suppliers can consistently produce parts that meet the required quality standards. PPAP is a critical step in the product development and manufacturing process, particularly in industries with stringent quality requirements.The main objectives of PPAP are to:

1. Demonstrate Capability: Suppliers need to demonstrate their ability to produce parts consistently and meet the specifications defined by the customer.
2. Verify Processes: PPAP ensures that the production processes are well-defined, controlled, and capable of producing parts that meet the required quality levels.
3. Identify and Mitigate Risks: By conducting a thorough review of the production processes and part characteristics, potential risks and issues can be identified and addressed before full-scale production begins.
4. Provide Evidence: PPAP serves as evidence that the supplier has met all customer requirements and is ready to commence production.

PPAP involves several key elements and documentation, including:

1. Part Submission Warrant (PSW): A document signed by the supplier’s authorized representative, indicating that all PPAP requirements have been met.
2. Design Records: Detailed engineering drawings, specifications, and other technical documentation related to the part.
3. Engineering Change Documents (if applicable): Any changes to the part design or manufacturing process must be documented and communicated.
4. Process Flow Diagram: A visual representation of the production process, including all stages and steps involved.
5. Process Failure Mode and Effects Analysis (PFMEA): A risk assessment tool used to identify potential failure modes in the production process and their effects on the part’s quality.
6. Control Plan: A plan that outlines the key controls and inspections at each stage of production to ensure quality requirements are met.
7. Measurement System Analysis (MSA): An assessment of the measurement tools and techniques used to inspect the parts, ensuring accurate and reliable measurements.
8. Dimensional Results: Detailed measurements of the part, demonstrating that it meets the required specifications.
9. Material Certifications: Certificates from the material suppliers confirming the quality and specifications of the raw materials used.
10. Appearance Approval Report (AAR): A report demonstrating that the part’s appearance meets the customer’s aesthetic requirements.
11. Initial Sample Inspection Report (ISIR): A report summarizing the results of the initial part inspection.
12. Records of Compliance: Records demonstrating compliance with customer-specific requirements and any industry or regulatory standards.

Once all the PPAP documentation is complete and approved, the supplier is authorized to proceed with production. PPAP is usually conducted for new parts or significant changes to existing parts and is typically required before full production begins or when transitioning to a new supplier. The specific PPAP requirements may vary depending on the customer and industry standards.

Prototypes are early samples, models, or releases of products built to test a concept or process.Generally, prototypes are used by system analysts and users to improve the precision of a new design. Prototyping is an essential step in the Design Thinking process and is often used in the final testing phase. Every product has a target audience and is designed to solve their problems in some way. To assess whether a product really solves its users’ problems, designers create an almost-working model or mock-up of the product, called a prototype, and test it with prospective users and stakeholders. Thus, prototyping allows designers to test the practicability of the current design and potentially investigate how trial users think and feel about the product. It enables proper testing and exploring design concepts before too many resources get used.A prototype is a product built to test ideas and changes until it resembles the final product. You can mock-up every feature and interaction in your prototype as in your fully developed product, check if your idea works, and verify the overall user-experience (UX) strategy. Prototyping allows you to build simple, small-scale prototypes of your products, and use them to observe, record, and assess user performance levels or the users’ general behavior and reactions to the overall design. Designers can then make appropriate refinements or possible alterations in the right direction. Design and development of a prototype program can be a challenging and iterative process.

Your design and development project plan must include your prototype program. Use a prototype control plan to manage the development of a specific product. Use existing approved suppliers, tooling and manufacturing processes to save time and risk. Monitor internal and supplier activities to both your design and development project plan as well as your prototype control plan. You must have a process for outsourcing activities (e.g. tooling). You must include this process as part of your QMS.

Clause 8.3.4.3 Prototype program

If the customer asks for it, the organization must have a prototype program and control plan. They should aim to use the same suppliers, tools, and manufacturing processes as they plan to use in production, whenever possible. They need to keep an eye on all performance testing to make sure it’s done on time and meets the requirements. If they hire others for services, they must make sure their quality management system covers how they control those services to ensure they meet the requirements.

The standard requires the supplier to have a prototype program when required by the customer and to use the same subcontractors, tooling, and processes as will be used in production. There will be situations where the customer requires a prototype program but when no such requirement has been stated it does not mean you should not produce prototypes. Prototypes will not normally be required when the design is similar to a previously proven design or standard or the design is so simple that sufficient evidence can be obtained during the production trial run. Many different types of models may be needed to aid product development, test theories, experiment with solutions, etc. However, when the design is complete, prototype models representative in all their physical and functional characteristics to the production models may need to be produced. When building prototypes, the same materials, locations, subcontractors, tooling, and processes should be used as will be used in production, so as to minimize the variation.Below is a step-by-step guide to help you design and develop a prototype program effectively:

1. Identify Objectives:
   • Clearly define the objectives of your prototype program. What problem or opportunity do you want to address with the prototype? What specific outcomes do you hope to achieve?
2. Research and Analysis:
   • Conduct thorough research to understand the context and background of the problem or opportunity.
   • Analyze existing solutions or similar prototypes to gain insights and avoid reinventing the wheel.
3. Define Scope and Constraints:
   • Clearly outline the scope of your prototype program, including its limitations and constraints (e.g., budget, time, resources).
   • Identify the target audience or end-users for the prototype.
4. Conceptualization and Ideation:
   • Brainstorm ideas and concepts for the prototype, considering different approaches and features.
   • Create sketches, diagrams, or wireframes to visualize the prototype’s potential layout and functionality.
5. Select Tools and Technologies:
   • Choose the appropriate tools, technologies, and programming languages for building the prototype.
   • Consider whether you will develop a software-based prototype, a hardware prototype, or a combination of both.
6. Development:
   • Start building the prototype based on the concepts and designs from the previous steps.
   • Focus on creating a minimum viable product (MVP) that demonstrates the core functionality and key features.
7. Iterative Improvement:
   • Test the prototype with real users or stakeholders to gather feedback.
   • Use this feedback to make iterative improvements to the prototype, enhancing its usability and addressing any issues.
8. User Experience (UX) Design:
   • Pay attention to the user experience and interface design of the prototype.
   • Ensure the prototype is intuitive, user-friendly, and aligns with the needs of the target audience.
9. Testing and Quality Assurance:
   • Conduct thorough testing to identify and fix bugs, errors, and performance issues.
   • Verify that the prototype functions as intended and meets the defined objectives.
10. Documentation:
    • Document the entire design and development process, including the rationale behind design decisions and changes made during iterations.
    • Create user manuals or guides for the prototype’s usage.
11. Presentation and Feedback Gathering:
    • Present the prototype to stakeholders, team members, or potential users.
    • Gather feedback and suggestions for further improvements or potential expansion of the prototype.
12. Finalize and Refine:
    • Based on the feedback received, finalize the prototype and make any necessary refinements.
    • Ensure that the prototype aligns with the original objectives and requirements.
13. Deployment and Evaluation:
    • Deploy the prototype in real-world scenarios if applicable.
    • Evaluate the effectiveness of the prototype in achieving its objectives.
    • Use this evaluation to decide on the next steps, such as full-scale development or further refinement.

Remember that prototyping is an iterative process, and it’s normal to make changes and improvements along the way. Stay open to feedback and be willing to adapt your prototype program to achieve the best possible results.

Using the same suppliers, tooling, and manufacturing processes in prototyping as in Productions.

Using the same suppliers, tooling, and manufacturing processes during prototyping as will be used in production is a best practice in product development. This approach is commonly known as Design for Manufacturability (DFM) or Design for Manufacturing (DFM). It aims to ensure a smooth transition from the prototyping phase to full-scale production by minimizing potential issues and risks that may arise during the transition.Here are some key reasons why using the same suppliers, tooling, and manufacturing processes in both prototyping and production is beneficial:

1. Consistency: By using the same suppliers and manufacturing processes, you can maintain consistency in the materials, components, and methods used in both prototyping and production. This reduces the chances of unexpected variations and ensures that the final product matches the prototype closely.
2. Early Issue Identification: Using production-intent tooling and processes during prototyping allows you to identify any potential manufacturing issues early in the development cycle. Addressing these issues at the prototyping stage is generally more cost-effective than discovering and resolving them during full-scale production.
3. Time and Cost Savings: By minimizing changes between prototyping and production, you can save time and money. Revising tooling or changing suppliers after prototyping can lead to delays and additional expenses.
4. Improved Product Quality: Ensuring that the same suppliers and manufacturing processes are used helps maintain the quality of the final product. Lessons learned during prototyping can be directly applied to the production process, resulting in a higher-quality end product.
5. Supply Chain Management: Using the same suppliers allows you to establish a relationship and understanding of their capabilities. This enables better communication and coordination throughout the development process and in the long term.
6. Faster Time to Market: When the transition from prototyping to production is smoother, it shortens the overall product development timeline, helping you get the product to market faster.

However, it’s important to note that in certain cases, especially for complex or high-tech products, initial prototyping might involve using different methods or suppliers to quickly test concepts or feasibility. Once the concept is validated, the shift to using the production-intent suppliers and processes should be made to ensure the advantages mentioned above.Overall, using the same suppliers, tooling, and manufacturing processes during prototyping and production is a strategic decision that helps ensure a successful product launch and efficient production process.

Monitoring of performance-testing activities of Prototyping

Monitoring performance-testing activities during prototyping is essential to ensure that the testing is conducted effectively and meets the necessary requirements. Proper monitoring helps identify potential issues early in the development process, allowing for timely adjustments and improvements. Here are some key aspects of monitoring performance-testing activities during prototyping:

1. Timely Completion: Performance-testing activities should have well-defined timelines and milestones. Regular monitoring allows you to track progress and identify any delays or bottlenecks in the testing process. By addressing these issues promptly, you can ensure that the testing stays on schedule and does not impact the overall development timeline.
2. Conformity to Requirements: Each performance-testing activity must be aligned with specific requirements and objectives. By closely monitoring the testing process, you can verify that the tests are conducted according to the established criteria. This ensures that the results are meaningful and accurately reflect the prototype’s performance in meeting its intended purpose.
3. Quality Assurance: Monitoring helps maintain the quality and integrity of the performance-testing process. It allows you to spot any deviations or inconsistencies that may arise during testing. Addressing these deviations promptly ensures the reliability of the test results and prevents potential issues from carrying over into production.
4. Issue Identification and Resolution: Performance testing may reveal flaws or weaknesses in the prototype’s design or functionality. Monitoring the testing activities enables the identification of such issues early on, making it easier to resolve them during the prototyping phase. This can lead to significant cost savings compared to addressing issues in later stages of development or during production.
5. Feedback Loop: Monitoring provides valuable feedback to the development team and stakeholders. This feedback helps improve the understanding of the prototype’s performance and aids in making informed decisions about design changes or optimizations.
6. Documentation and Reporting: Proper monitoring facilitates comprehensive documentation of the performance-testing activities. This documentation serves as a valuable reference for future iterations of the prototype and can also be used to demonstrate compliance with testing requirements to relevant stakeholders.
7. Risk Management: Monitoring performance-testing activities allows you to identify potential risks that may impact the success of the prototyping process. By recognizing these risks early, appropriate risk mitigation strategies can be put in place to minimize their impact.

In conclusion, monitoring performance-testing activities during prototyping is crucial for successful product development. It ensures that the testing is completed on time, aligns with the specified requirements, and helps identify and address issues before moving into full-scale production. This proactive approach contributes to the overall quality and reliability of the final product.

Outsourcing of Prototyping service

It is essential to establish a robust quality management system (QMS) that includes clear guidelines for controlling the outsourced services. This ensures that the outsourced prototyping aligns with the organization’s requirements and maintains the desired level of quality. Here are key steps and considerations for including outsourced prototyping within the scope of the QMS:

1. Define Requirements and Expectations: Clearly specify the requirements and expectations for the outsourced prototyping services. This should include technical specifications, performance criteria, timelines, and any other relevant criteria that the prototype must meet.
2. Select Qualified Suppliers: Thoroughly evaluate potential suppliers before outsourcing the prototyping. Consider factors such as their experience, capabilities, track record, and adherence to quality standards. Choose suppliers who demonstrate the ability to meet the organization’s requirements and deliver high-quality prototypes.
3. Documented Agreements and Contracts: Establish formal agreements or contracts with the chosen suppliers that clearly outline the scope of work, responsibilities, quality requirements, and any other relevant terms. These agreements serve as a reference point to ensure that the outsourced services align with the organization’s expectations.
4. Risk Assessment and Mitigation: Conduct a risk assessment to identify potential risks associated with outsourcing the prototyping activities. Develop appropriate risk mitigation strategies to address these risks and ensure the continuity of the project.
5. Communication and Collaboration: Foster open and clear communication channels with the outsourced suppliers. Collaboration and regular communication are essential to address any issues, provide clarifications, and keep track of progress.
6. Monitoring and Performance Evaluation: Implement a system to monitor and evaluate the performance of the outsourced prototyping services. Regularly review the progress, quality of deliverables, and adherence to requirements. This evaluation helps identify any deviations or potential areas of improvement.
7. Quality Audits and Inspections: Conduct periodic quality audits or inspections of the outsourced prototyping processes. These audits verify compliance with the organization’s quality standards and identify any non-conformities that need corrective actions.
8. Non-Conformance Management: Establish a process for handling non-conformances identified during the outsourced prototyping. This should include corrective and preventive actions to rectify issues and prevent recurrence.
9. Training and Competency: Ensure that personnel involved in overseeing the outsourced prototyping understand the quality requirements and are competent to assess the quality of the delivered prototypes.
10. Continuous Improvement: Continuously improve the outsourcing process by learning from past experiences, feedback, and performance evaluations. Implement corrective actions and drive process enhancements to enhance the effectiveness of outsourced prototyping.

By incorporating these measures into the organization’s QMS, the organization can ensure that outsourced prototyping services conform to the required quality standards and align with the organization’s objectives, ultimately contributing to the successful development of the final product.

In the automotive industry, design and development validation is a crucial phase of the product development process. It involves comprehensive testing and evaluation to ensure that vehicles, components, and systems meet the required specifications, safety standards, and regulatory requirements. This validation process verifies that the automotive products perform as intended, are reliable, and meet customer expectations. It includes various types of testing, such as performance testing, durability testing, crash testing, environmental testing, and more. Through design and development validation, automotive manufacturers ensure the quality, safety, and compliance of their products, leading to enhanced customer satisfaction and confidence in the automotive market. Verification is checking product or process to input requirements, whereas validation is checking product or process is suitable for it’s intended use –  does it perform/function in the way intended by your customer or your organization.Product design Verification includes – design reviews ; comparing the new design to a similar proven design if available; performing alternate calculations; performing tests and simulations; reviewing the design documents before release, etc.Manufacturing process design verification include – design review ; process capability studies; testing various process parameters; performing tests and trials; reviewing the manufacturing process design documents before release, etc.Product and manufacturing process validation includes – design reviews; comparison between customer requirements and internal development plans; d & d validation against customer requirements and d & D input requirements; corrective action and lessons learned from documented process failures and product nonconformities. You must keep records for both verification and validation activities

Design and development validation in the automotive industry is a critical process that ensures the quality, safety, and compliance of vehicles before they are manufactured and released to the market. The validation process involves testing and verifying various components, systems, and the overall vehicle performance to meet regulatory standards and customer expectations. Here are the key steps and considerations in design and development validation:

1. Requirements Definition: Clearly define the performance, safety, and regulatory requirements for the vehicle. These requirements serve as the baseline for the validation process.
2. Validation Plan: Develop a comprehensive validation plan that outlines the scope, objectives, testing methods, resources, and schedule for the validation activities.
3. Simulations and Computer-Aided Engineering (CAE): Use advanced simulations and CAE tools to evaluate the design’s performance virtually. This allows engineers to identify potential issues and make improvements early in the development process.
4. Component Testing: Validate individual vehicle components (e.g., engine, transmission, brakes, etc.) through rigorous testing to ensure they meet the specified requirements.
5. Prototype Testing: Build and test vehicle prototypes to evaluate their performance under various conditions and stress factors. This includes testing on test tracks, proving grounds, and in controlled environments.
6. Environmental Testing: Subject vehicles to extreme environmental conditions such as extreme temperatures, humidity, and altitudes to ensure they can operate reliably in different climates.
7. Safety Testing: Conduct crash tests and other safety evaluations to ensure the vehicle meets safety standards and protects occupants in the event of a collision.
8. Emissions and Compliance Testing: Verify that the vehicle meets emissions standards and complies with regulations set by various governing bodies.
9. Durability Testing: Assess the durability and longevity of components and the overall vehicle by simulating real-world wear and tear over an extended period.
10. Noise, Vibration, and Harshness (NVH) Testing: Evaluate the vehicle’s NVH characteristics to ensure a comfortable and quiet driving experience.
11. Software Validation: Validate the functionality and performance of the vehicle’s software systems, including infotainment, connectivity, and advanced driver-assistance systems (ADAS).
12. User Experience (UX) Testing: Gather feedback from potential users through focus groups and usability testing to improve the vehicle’s overall user experience.
13. Regulatory Compliance: Ensure that the vehicle design complies with all relevant regulations and safety standards set by the automotive industry and government agencies.
14. Continuous Improvement: Iterate the design based on validation findings and continuously improve the vehicle’s performance, safety, and efficiency.

Throughout the validation process, detailed records and documentation are maintained to demonstrate compliance with standards and regulations. Additionally, collaboration between different teams, including design, engineering, manufacturing, and testing, is crucial to ensuring the vehicle’s successful validation.By following a robust design and development validation process, automotive manufacturers can produce vehicles that are reliable, safe, and meet the expectations of customers and regulatory bodies.

Clause 8.3.4.2 Design and development validation

According to the requirements specified by the customer and relevant industry and governmental regulatory standards, validation of design and development must be conducted. This validation should be planned to align with the timing specified by the customer, if applicable. If contractually agreed upon with the customer, this validation should also involve assessing how the organization’s product, including embedded software, interacts within the final customer’s product system.

Design and development validation in the automotive industry must be performed according to the requirements specified by the customer, as well as the applicable industry standards and governmental agency-issued regulatory standards. These requirements serve as the foundation for the entire validation process and ensure that the final product meets the necessary quality, safety, and compliance standards. The customer’s requirements are essential as they represent the specific needs and expectations of the end-users, whether they are individual consumers or businesses. Meeting these requirements is crucial for customer satisfaction and market success. In addition to customer requirements, the automotive industry has established various standards and best practices that manufacturers must adhere to. These standards cover a wide range of aspects, including safety, emissions, performance, and quality. Adhering to industry standards helps ensure that the vehicles produced are reliable, safe, and perform as expected. Moreover, governmental agencies, such as the National Highway Traffic Safety Administration (NHTSA) in the United States or the European Commission, issue regulatory standards that vehicles must meet to be legally sold in specific regions. These regulations are designed to protect the public’s safety and welfare and often cover areas such as crashworthiness, emissions, fuel efficiency, and more. By aligning the design and development validation process with these requirements, automotive manufacturers can produce vehicles that not only satisfy customer needs but also comply with legal and regulatory obligations. This, in turn, promotes trust and confidence in the automotive industry and contributes to the overall safety and quality of vehicles on the roads.

The standard requires that design validation be performed to ensure that product conforms to defined user needs and/or requirements. Merely requiring that the design output meets the design input would not produce a quality product or service unless the input requirements were a true reflection of the customer needs. If the input is inadequate the output will be inadequate: “garbage in, garbage out” to use a common software expression. However, the standard does not
require user needs or requirements to be specified. User needs and requirements should be specified also as part of the design input requirements, but if they are, design validation becomes part of design verification. Design validation is a process of evaluating a design to establish that it fulfills the intended user requirements. It goes further than design verification, in that validation tests and trials may stress the product of such a design beyond operating conditions in order to establish design margins of safety and performance. Design validation can also be performed on mature designs in order to establish whether they will fulfill different user requirements to the original design input requirements. An example is where software designed for one application can be proven fit for use in a different application or where a component designed for one environment can be shown to possess a capability which would enable it to be used in a different environment. Multiple validations may there fore be performed to qualify the design for different applications. Design validation may take the form of qualification tests which stress the product up to and beyond design limits — beta tests where products are supplied to several typical users on trial in order to gather operational performance data, performance trials, and reliability and maintainability trials where products are put on test for prolonged periods to
simulate usage conditions. In the automobile industry the road trials on test tracks are validation tests as are the customer trials conducted over several weeks or months under actual operating conditions on pre-production models. Sometimes the trials are not successful as was the case of the “Copper Cooled Engine” in General Motors in the early 1920s. Even though the engine seemed to work in the laboratory, it failed in service. Production was commenced before the design had been validated. The engine had pre-ignition problems and showed a loss of compression and power when hot. As a result, many cars with the engine were scrapped. Apart from the technical problems GM experienced with its development, it did prove to be a turning point in GM’s development strategy, probably resulting in what is now their approach to product quality planning. Other examples are beta tests or public testing conducted on software products where tens or hundreds of products are distributed to designated customer sites for trials under actual operating conditions before product launch. Sometimes, commercial pressures force termination of these trials and products are launched prematurely in order to beat the competition. The supplementary requirement stipulates that design validation should occur in conjunction with customer programming requirements and ideally design validation of the original design should be complete before product is launched into production. Thereafter, it may be performed at any stage where the design is selected for a different application. However, for the original design the scale of the tests and trials may be such that a sufficiently high degree of confidence has been gained before the end of the trials for pre-production to commence. Some of the trials may take years. The proving of reliability, for instance, may require many operating hours before enough failures have been observed to substantiate the reliability specification. There is no mean time between failure (MTBF) until you actually have a failure, so you need to keep on test ing until you know anything meaningful about the product’s reliability. During the design process many assumptions may have been made and will require proving before commitment of resources to the replication of the design. Some of the requirements, such as reliability and maintainability, will be time-dependent. Others may not be verifiable without stressing the product beyond its design limits. With computer systems, the wide range of possible variables is so great that proving total compliance would take years. It is however necessary to subject a design to a series of tests and examinations in order to verify that all the requirements have been achieved and that features and characteristics will remain stable under actual operating conditions. With some parameters a level of confidence rather than certainty will be acceptable. Such tests are called qualification tests. These differ from other tests because they are designed to establish the design margins and prove the capability of the design. As the cost of testing vast quantities of equipment would be too great and take too long, qualification tests, particularly on hardware, are usually performed on a small sample. The test levels are varied to take account of design assumptions, variations in production processes and the operating environment. Products may not be put to their design limits for some time after their launch into service, probably far beyond the warranty period. Customer complaints may appear years after the product launch. When investigated this may be traced back to a design fault which was not tested for during the verification program. Such things as corrosion, insulation, resistance to wear, chemicals, climatic conditions, etc. need to be verified as being within the design limits. Following qualification tests, your customer may require a demonstration of performance in order to accept the design. These tests are called design acceptance tests. They usually consist of a series of functional and environmental tests taken from the qualification test specification, supported by the results of the qualification tests. When it has been demonstrated that the design meets all the specified requirements, a Design Certificate can be issued. It is the design standard which is declared on this certificate against which all subsequent changes should be controlled and from which production versions should be produced.

Process for controlling qualification tests and demonstrations should provide for:

• Test specifications to be produced which define the features and characteristics that are to be verified for design qualification and acceptance
• Test plans to be produced which define the sequence of tests, the responsibilities for their conduct, the location of the tests, and test procedures to be used
• Test procedures to be produced which describe how the tests specified in the test specification are to be conducted together with the tools and test equipment to be used and the data to be recorded
• All measuring equipment to be within calibration during the tests
• The test sample to have successfully passed all planned in—process and assembly inspections and tests prior to commencing qualification tests
• The configuration of the product in terms of its design standard, deviations, non conformities, and design changes to be recorded prior to and subsequent to the tests
• Test reviews to be held before tests commence to ensure that the product, facilities, tools, documentation, and personnel are in a state of operational readiness for verification
• Test activities to be conducted in accordance with the prescribed specifications, plans, and procedures
• The results of all tests and the conditions under which they were obtained to be recorded
• Deviations to be recorded, remedial action taken, and the product subject to re-verification prior to continuing with the tests
• Test reviews to be performed following qualification tests to confirm that sufficient objective evidence has been obtained to demonstrate that the product fulfills the requirements of the test specification

The validation results to be recorded and design failures to be documented in the validation records. The corrective and preventive action procedures to be followed in addressing design failures. Preventive action cannot be taken on a failure that has occurred except on other future designs. What is intended is that remedial action is taken to correct the design fault and corrective action taken to prevent the same failure arising again either in the same design or in other designs.

Alignment with customer-specified timing

The timing of design and development validation in the automotive industry should be carefully planned in alignment with the customer-specified timing. This means that the validation activities should be scheduled and coordinated to meet the deadlines and milestones set by the customer for the project.Here are some key points to consider regarding the timing of design and development validation:

1. Clear Communication: From the outset of the project, there should be clear and open communication between the automotive manufacturer and the customer regarding the validation process and its timeline. Understanding the customer’s expectations and requirements is crucial for planning the validation activities effectively.
2. Validation Plan: Develop a comprehensive validation plan that outlines the specific validation activities, their scope, and their respective timelines. This plan should be reviewed and agreed upon by both the automotive manufacturer and the customer.
3. Milestone Checkpoints: Identify key milestones throughout the design and development process where validation progress can be reviewed. This allows both parties to ensure that the project is on track and that validation activities are being executed according to the planned timing.
4. Prototyping and Iteration: Utilize rapid prototyping and iteration to address any potential issues early in the development process. This approach enables timely adjustments to the design and validation strategy, reducing the risk of delays.
5. Collaboration and Coordination: Establish effective collaboration and coordination between different teams involved in the validation process, including design, engineering, testing, and project management. This helps ensure that everyone is working towards the common goal of meeting the customer-specified timing.
6. Contingency Planning: Develop contingency plans in case of unexpected delays or challenges during the validation process. Having alternative strategies in place can help mitigate risks and keep the project on schedule.
7. Customer Involvement: Where appropriate, involve the customer in the validation process, especially during critical stages or for user-specific requirements. Their input and feedback can be valuable in refining the design and validating the final product.
8. Regulatory Considerations: Take into account any regulatory requirements or certifications that may impact the timing of validation. Ensuring compliance with regulatory standards is essential, and it may influence the overall project timeline.

By planning the design and development validation in alignment with customer-specified timing, automotive manufacturers can deliver products that meet customer expectations, demonstrate responsiveness to customer needs, and foster a positive working relationship with their clients. Moreover, timely validation helps bring vehicles to market faster, gaining a competitive advantage in the automotive industry.

Evaluating the interaction of the organization’s product within the final customer’s product system.

The validation of design and development in the automotive industry involves evaluating not only the individual components and systems of the vehicle but also the interaction of the organization’s product within the entire system of the final customer’s product. This aspect is particularly important when considering the increasing complexity of modern vehicles, which often include embedded software and various interconnected systems.Here are some key points to consider when evaluating the interaction of the organization’s product within the final customer’s product system:

1. Integration Testing: Test the integration of various vehicle systems and components to ensure they work together seamlessly. This involves checking the compatibility and communication between different software and hardware elements.
2. System-Level Testing: Perform tests that encompass the entire vehicle system, including all software, electronics, mechanical components, and interfaces. This ensures that the entire vehicle functions as intended.
3. Interoperability Testing: Evaluate how the organization’s product interacts with other components or systems that may come from different suppliers. Ensuring interoperability is crucial to avoid compatibility issues.
4. Safety-Critical Systems: If the vehicle includes safety-critical systems (e.g., advanced driver-assistance systems), conduct thorough testing to ensure they work reliably and do not compromise overall safety.
5. User Interface and User Experience Testing: Evaluate how the organization’s product interacts with the end-users, including the usability of embedded software interfaces and controls.
6. Functional and Non-Functional Testing: Validate not only the functional aspects of the organization’s product but also non-functional aspects such as performance, reliability, and security.
7. Real-World Scenario Testing: Conduct testing in real-world scenarios to simulate how the vehicle will perform in different driving conditions and situations.
8. Validation in Customer Environment: If possible, perform testing in the customer’s environment to ensure that the product functions as intended within the specific context of its usage.
9. Feedback and Iteration: Gather feedback from customers and end-users to identify areas for improvement and iterate the design accordingly.
10. Compliance with Industry Standards: Ensure that the organization’s product meets relevant industry standards, such as ISO 26262 for automotive functional safety or ISO 16949 for quality management.

By evaluating the interaction of the organization’s product within the final customer’s product system, automotive manufacturers can identify and resolve potential issues early in the development process. This comprehensive approach to validation helps ensure that the vehicle performs as expected and meets both customer requirements and regulatory standards.

The standard requires that You shall define, analyze and report measurements at specified stages of Design and Development to the management and customer at different stages . A design represents a considerable investment by the organization. There is therefore a need for a formal mechanism for management and the customer to evaluate designs at major milestones. The purpose of the review is to determine whether the proposed design solution is compliant with the design requirement and should continue or should be changed before proceeding to the next phase. It should also determine whether the documentation for the next phase is adequate before further resources are committed. It is that part of the design control process which measures design performance, compares it with predefined requirements and provides feedback so that deficiencies may be corrected before the design is released to the next phase. Although design documents may have been through a vetting process, the purpose is not to review documents but to subject the design to an independent experts for its judgement as to whether the most satisfactory design solution has been chosen. By monitoring, flaws in the design may be revealed before it becomes too costly to correct them. It also serve to discipline designers by requiring them to document the design logic and the process by which they reached their conclusions, particularly the options chosen and the reasons for rejecting other options. The monitoring process involves systematic observation, measurement, and evaluation of the design and development activities to ensure they are progressing as planned and producing the desired outcomes. Here are some key aspects of monitoring design and development in IATF 16949:

1. Performance Metrics and Indicators: Define key performance indicators (KPIs) and metrics to measure the progress and effectiveness of the design and development process. These metrics could include design cycle time, number of design changes, customer feedback on prototypes, etc.
2. Project Management Techniques: Utilize project management techniques, such as Gantt charts, milestone tracking, and progress reports, to monitor the status of design and development projects and ensure they are on schedule.
3. Design Reviews: Conduct regular design reviews at specified stages of the development process to evaluate the design’s completeness, compliance with requirements, and potential risks.
4. Risk Assessment and Mitigation: Continuously assess risks associated with the design and development process and implement appropriate mitigation strategies to address potential issues.
5. Traceability and Documentation: Ensure proper traceability of design decisions, changes, and approvals through well-maintained documentation, such as design records, change logs, and version control.
6. Validation and Verification: Monitor the validation and verification activities to ensure that the design outputs meet the intended requirements and are validated against customer needs.
7. Customer Input and Feedback: Regularly gather customer input and feedback throughout the design and development process to validate the design’s alignment with customer requirements and expectations.
8. Compliance with Requirements: Monitor compliance with IATF 16949 requirements and any applicable statutory and regulatory requirements related to design and development.
9. Corrective and Preventive Actions: Monitor the implementation of corrective and preventive actions identified during design reviews or other assessments to address issues and improve the design process.
10. Continuous Improvement: Foster a culture of continuous improvement by analyzing data and feedback from design and development activities to identify opportunities for enhancing efficiency and quality.

By effectively monitoring the design and development process, automotive organizations can identify potential issues early, ensure compliance with requirements, and deliver products that meet customer expectations and industry standards. Monitoring helps in timely decision-making, risk management, and ultimately contributes to the successful realization of high-quality automotive products.

Clause 8.3.4.1 Monitoring

At specified stages during the design and development of products and processes measurements such as appropriate quality risks, costs, lead times, critical paths, and other measurements must be defined, analysed, and reported with summary results as an input to management review. Also at specified stages as agreed by the customer these measurements will be reported to the customers.

At one or more milestones of the Design and Development project, depending on customer requirements, the size, complexity and risks involved, measurements of Design and developments must be analysed and reported to the management and the customers. The purpose is to evaluate results to requirements, check project progress and costs to plan and take actions on any problems encountered. You must take multi-disciplinary approach for doing these reviews and keep appropriate records of issues discussed, actions to be taken, responsibilities and timeline for completion. This must be included in your Design and Development plan.The summary of measurements at specific stages of Design and Development must be added to the management review agenda .

Scheduling of Design and Development monitoring

A schedule of design measurement should be established for each product/service being developed. In some cases there will need to be only one design review after completion of all design verification activities. However, depending on the complexity of the design and the risks, you may need to measure the design at some or all of the following intervals:

Design Requirement — to establish that the design requirements can be met and reflect the needs of the customer before commencement of design
Conceptual Design — to establish that the design concept fulfills the requirements before project definition commences
Preliminary Design — to establish that all risks have been resolved and development specifications produced for each sub-element of the product/service before detail design commences
Critical Design — to establish that the detail design for each sub-element of the product/service complies with its development specification and that product specifications have been produced before manufacture of the prototypes
Qualification Readiness — to establish the configuration of the baseline design and readiness for qualification before commencement of design proving
Final Design — to establish that the design fulfills the requirements of its development specification before preparation for its production

Participants at design monitoring
The input data for the monitoring should be distributed and examined by the team well in advance of the time when a decision on the design has to be made. Often analysis may need to be performed on the input data by the participants in order for them to determine whether the design solution is the most practical and cost effective way of meeting the requirements. The standard requires that participants at each design review include representatives of all functions concerned with the design stage being reviewed, as well as other specialist personnel as required. The team should have a collective competency greater than that of the designer of the design. Design reviews are performed by management than the designers, in order to release a design to the next phase of development. A review is another look at something. The designer has had one look at the design and when satisfied presents the design to the management and customer so as to seek approval and permission to go ahead with the next phase. A designer may become too close to the design to spot errors or omissions and so will be biased towards the standard of his/her own performance. The designer may welcome the opinion of someone else as it may confirm that the right solution has been found or that the requirements can’t be achieved with the present state of the art. If a design is inadequate and the inadequacies are not detected before production commences the consequences may well be disastrous. A poor design can lose a customer, a market, or even a business so the advice of independent experts should be valued. The team should comprise, as appropriate, representatives of the purchasing, manufacturing, servicing, marketing, inspection, test, reliability, QA authorities, etc. as a means of gathering sufficient practical experience to provide advance warning of potential problems with implementing the design. The chairman of the team should be the authority responsible for placing the development requirement and should make the decision as to whether design should proceed to the next phase based on the evidence substantiated by the team.

Measurements for Design and development of products and processes

When it comes to the design and development of products and processes, there are several essential measurements that organizations use to ensure efficiency, quality, and successful outcomes. Here are some key measurements to consider:

1. Quality Risks: Identify and assess potential risks related to the product or process design. This includes evaluating risks associated with materials, manufacturing processes, technological challenges, and compliance issues. Utilize risk assessment techniques like Failure Mode and Effects Analysis (FMEA) to prioritize and mitigate risks.
2. Costs: Keep track of all costs involved in the design and development process, including research and development expenses, materials, equipment, labor, and any other associated expenses. Regularly review and analyze cost data to manage budgets effectively.
3. Lead Times: Measure the time taken to complete different stages of the design and development process. This includes lead times for conceptualization, prototyping, testing, and final production. Shortening lead times can improve time-to-market and increase competitiveness.
4. Critical Paths: Identify the critical path in the product or process development. The critical path is the sequence of activities that determine the project’s overall timeline. Any delays in critical path activities will directly impact the project’s completion date.
5. Design and Development Cycle Time: Measure the time taken from the initial design concept to the final implementation and launch. This metric helps identify inefficiencies and bottlenecks in the development process.
6. Product Performance Metrics: Define and measure specific performance metrics related to the product’s functionality, reliability, durability, and user experience. This includes factors like product failure rates, warranty claims, and customer satisfaction.
7. Design Efficiency Metrics: Assess the efficiency of the design process, including the number of design iterations, the time taken to finalize designs, and the proportion of successful designs to failed ones.
8. Innovation Index: Develop a metric to gauge the level of innovation in the product or process design. This could be measured by the number of new patents, breakthrough features, or novel manufacturing techniques introduced.
9. Customer Feedback and User Testing: Gather feedback from customers and conduct user testing to understand how well the product meets their needs and expectations. This data can guide continuous improvements.
10. Return on Investment (ROI): Calculate the return on investment for the design and development effort. Compare the costs incurred with the benefits obtained, such as increased sales, cost savings, or competitive advantage.
11. Environmental Impact: Evaluate the environmental impact of the product or process design. This could include assessing carbon footprint, resource usage, and waste generation, aiming for more sustainable practices.

Regularly reviewing these measurements and key performance indicators (KPIs) throughout the design and development process enables organizations to make data-driven decisions, identify areas for improvement, and optimize their strategies for success.

Reporting to the customers

When reporting product and process development activities to customers at specified stages, it’s essential to provide clear and concise information that highlights progress, milestones, and key performance metrics. Here’s a structured approach to reporting:

1. Define Reporting Stages: Determine the specific stages at which you will provide updates to customers. Common stages may include project initiation, concept development, prototype completion, testing/validation, and final production.
2. Executive Summary: Start each report with a brief executive summary that gives an overview of the current stage’s progress, achievements, and any significant developments since the last report.
3. Key Objectives: Outline the objectives of the current stage. Specify what the team aimed to accomplish during this phase of the development process.
4. Progress Overview: Provide a summary of the progress made in the development process. Mention any completed tasks, achieved milestones, and deliverables. Use bullet points or visuals like charts to make the information more accessible.
5. Quality Metrics: Report on the quality measurements and risk assessments conducted during the stage. Highlight any potential risks identified and the steps taken to mitigate them. Include data on quality checks, tests performed, and outcomes.
6. Costs and Budgets: Present the financial aspect of the project, including the budget allocated for the current stage, actual expenditures, and any budgetary changes or challenges encountered.
7. Lead Times and Critical Paths: Communicate the time taken for various activities during this stage and how they relate to the critical path. Address any delays or issues affecting the overall timeline.
8. Design and Development Cycle Time: Report on the total time taken from the start of the stage to its completion. Compare this with the planned timeline to assess whether the project is on track.
9. Product Performance Updates: Share data on product performance metrics, such as functionality, reliability, and user experience. Include any user testing results and feedback gathered from stakeholders.
10. Customer Feedback and Satisfaction: If applicable, summarize customer feedback collected during the stage and indicate how it influenced decisions and improvements.
11. Innovation and Unique Features: If there have been any innovations or unique features introduced during the development, highlight them and explain their potential benefits.
12. Next Steps: Provide an outline of the upcoming activities and goals for the next stage. Discuss any changes in the project plan and their implications.
13. Challenges and Mitigation Plans: Be transparent about any challenges faced during the stage and the measures taken to address them.
14. Conclusion: Conclude the report by summarizing the overall progress, reiterating key achievements, and expressing gratitude for the customer’s ongoing support and collaboration.
15. Appendix (Optional): If there are detailed technical specifications, additional data, or supporting documentation, include it in an appendix for interested stakeholders to reference.

Remember that the reporting format and level of detail may vary based on the nature of the project, the preferences of your customers, and the complexity of the development process. Always tailor the reports to meet the specific needs and expectations of your audience.

Manufacturing process design is the systematic planning and optimization of the processes involved in transforming raw materials or components into finished products. It encompasses a series of activities that aim to create an efficient, cost-effective, and reliable production system. During the manufacturing process design, various factors are considered, including product specifications, design requirements, material characteristics, production volumes, and quality standards. The goal is to develop a detailed road map that outlines the sequence of operations, the use of machinery and equipment, workforce allocation, quality control measures, and testing protocols. By carefully designing the manufacturing process, organizations can enhance productivity, reduce waste and defects, ensure product consistency, and meet customer demands effectively. Moreover, process design also plays a vital role in optimizing resource utilization, reducing production lead times, and maintaining compliance with industry regulations and standards.

11. Special Characteristics Identification and Control: Special characteristics of the product and process should be identified, and appropriate control measures should be implemented to ensure their compliance with requirements.
12. Risk Management: The organization must assess risks associated with the manufacturing process and develop strategies to mitigate these risks.

By addressing these manufacturing process design inputs, organizations can ensure that their manufacturing processes are capable of consistently producing high-quality products that meet customer requirements and comply with industry standards.

Clause 8.3.3.2 Manufacturing process design input

The organization needs to identify, document, and assess input requirements for manufacturing process design. This involves reviewing product design output data, including special characteristics, as well as setting targets for productivity, process capability, timing, and cost. It’s crucial to explore alternative manufacturing technologies and consider any customer requirements, along with insights from previous developments. The possibility of using new materials should also be explored. Additionally, factors such as product handling, ergonomics, design for manufacturing, and design for assembly need to be taken into account. Incorporating error-proofing methods into the manufacturing process design should be considered to an appropriate extent based on the severity of potential issues and the associated risks.

You must identify, document and review manufacturing process design input that include – product design output data; targets for productivity; process capability and cost; customer requirements for manufacturing, if any; and experience from past Design and Development projects and manufacturing activities; and the use of error-proofing methods appropriate to the size of problems and risks experienced. You must have a process to deploy (identify, document, review and use) manufacturing process design input information coming from various sources. Use a Project Schedule to manage the planning work. Input generally include: design objectives (output and specs summary of customer. Statutory, Regulatory and own requirements), customer schedule, lessons learned, product drawings and/or specs. Lessons learnt are from internal manufacturing records, FMEA history etc. Some OEM customers requires continuous recording during operations. This makes things easier when developing new parts. If your organization is making the product for the first time, the customer should be able to furnish lessons learned. Functional tests on products are still required, but expected to be much less as compared to product design. The organization can identify and review manufacturing process design input requirements through a systematic and collaborative approach. Here’s a step-by-step guide to this process:

1. Product Design Collaboration: Establish close collaboration between product design teams and manufacturing engineers. This ensures that the design team understands the manufacturing constraints and opportunities, allowing them to provide relevant and feasible input requirements.

12. Identification and Control of Special Characteristics: Identify special characteristics of the product and process and implement appropriate control measures.
13. Risk Management: Assess and manage risks associated with the manufacturing process.
14. Continuous Improvement and Review: Continuously review and update the manufacturing process design input requirements based on data analysis, feedback, and lessons learned from previous projects. Implement a feedback loop to incorporate improvements and address changing requirements.

By following these steps and involving relevant stakeholders, the organization can ensure that the manufacturing process design input requirements are comprehensive, accurate, and aligned with customer needs and quality standards. Regular reviews and continuous improvement efforts further enhance the effectiveness and efficiency of the manufacturing process.

Manufacturing process design input requirements

Manufacturing process design input requirements play a crucial role in developing efficient and effective production processes. The following is a comprehensive list of input requirements that should be considered during manufacturing process design:

1. Product Design Output Data Including Special Characteristics: Product design output data, such as specifications, drawings, and requirements, provide essential information for designing the manufacturing process. Special characteristics identified during product design must be incorporated into the process design to ensure their proper control.
2. Targets for Productivity, Process Capability, Timing, and Cost: Set specific targets for productivity, process capability (e.g., Cp, Cpk), timing (cycle times, lead times), and cost to align the manufacturing process with overall business goals and customer expectations.

By addressing these manufacturing process design input requirements, automotive companies can develop robust and efficient production processes that result in high-quality products, meet customer demands, and remain competitive in the industry.

Use of error proofing method to be included in the manufacturing process design

Error-proofing, also known as Poka-Yoke, is a critical method used in manufacturing process design to prevent errors and defects before they occur or to detect them at an early stage. By incorporating error-proofing techniques, automotive companies can improve product quality, reduce rework, and enhance overall process efficiency. Here are some ways error-proofing can be included in the manufacturing process design:

1. Designing Foolproof Processes: Implementing foolproof processes that make it impossible or difficult to produce defects. For example, using a unique keying mechanism to ensure that parts can only be assembled in the correct orientation.
2. Using Sensors and Automation: Integrating sensors and automated systems to detect anomalies during production. Automated inspections can identify deviations from specifications and trigger alerts or stop the process when necessary.
3. Visual Management: Utilizing visual cues, such as color-coding or labels, to indicate correct assembly steps and part orientations, making it easier for operators to follow the correct procedures.
4. Checklists and Standard Operating Procedures (SOPs): Providing clear checklists and SOPs for operators to follow during each step of the manufacturing process to reduce the likelihood of errors.
5. Andon Systems: Implementing Andon systems that enable workers to quickly signal supervisors or support teams if they encounter a problem during production, allowing for immediate intervention.
6. Error Detection with Poka-Yoke Devices: Using Poka-Yoke devices, like sensors, limit switches, or mechanical fixtures, to identify defects or deviations from specifications, and stopping the process if an error is detected.
7. Error Prevention through Jidoka (Autonomation): Incorporating Jidoka principles to empower machines to stop themselves when they encounter an abnormality, preventing the production of defective parts.
8. Incorporating Error-Proofing in Design for Manufacturing (DFM): Ensuring that the product design includes features and characteristics that are easy to manufacture and assemble, reducing the likelihood of errors during production.
9. Training and Skill Development: Providing comprehensive training to operators and workers on error-proofing techniques and the importance of adhering to standardized processes.
10. Root Cause Analysis (RCA): Conducting regular root cause analyses of defects and errors to identify the underlying causes and implement corrective actions to prevent recurrence.
11. Continuous Improvement Culture: Fostering a culture of continuous improvement, where employees are encouraged to identify and propose error-proofing ideas and implement them throughout the manufacturing process.

By incorporating error-proofing methods into the manufacturing process design, automotive companies can significantly reduce defects, enhance product quality, increase customer satisfaction, and optimize their production efficiency. Error-proofing is an integral part of lean manufacturing and Total Quality Management (TQM) principles, leading to enhanced competitiveness and success in the automotive industry.

The standard requires that design input requirements relating to the product be identified and documented. Design input requirements may in fact be detailed in the contract. The customer may have drawn up a specification detailing the features and characteristics product or service needs to exhibit. Alternatively, the customer needs may be stated in very basic terms; for example:

• For the fenders I require a decorative finish that is of the same appearance as the bodywork.
• For interior seating I require a durable fabric that will retain its appearance for the life of the vehicle and is not electrostatic.
• I require an electronic door locking system with remote control and manual override that is impervious to unauthorized personnel.

From these simple statements of need you need to gather more information and turn the requirement into a definitive specification. Sometimes you can satisfy your customer with an existing product or service, but when this is not possible you need to resort to designing one to meet the customer’s particular needs, whether the customer be a specific customer or the market in general. You should note that these requirements do not require that design input requirements be stated in terms which, if satisfied, will render the product or service fit for purpose -nor does it state when the design input should be documented. Design inputs should reflect the customer needs and be produced or available before any design commences. To identify design input requirements you need to identify:

• The purpose of the product or service
• The conditions (or environment) under which it will be used, stored, and transported o The skills and category of those who will use and maintain the product or service
• The countries to which it will be sold and the related regulations governing sale and
• use of products
• The special features and characteristics which the customer requires the product or service to exhibit, including life, reliability, durability, and maintainability
• The constraints in terms of time—scale, operating environment, cost, size, weight, or other factors
• The standards with which the product or service needs to comply
• The products or service with which it will directly and indirectly interface, and their features and characteristics
• The documentation required of the design output necessary to manufacture, procure, inspect, test, install, operate, and maintain a product or service

You have a responsibility to establish your customer requirements and expectations. If you do not determine conditions that may be detrimental to the product and you supply the product as meeting the customer needs and it subsequently fails, the failure is your liability. If the customer did not provide reasonable opportunity for you to establish the requirements, the failure may be the customer’s liability. If you think you may need some extra information in order to design a product that meets the customer needs, you must obtain it or declare your assumptions. A nil response is often taken as acceptance in full. In addition to customer requirements there may be industry practices, national standards, company standards, and other sources of input to the design input requirements to be taken into account. You should provide design guides or codes of practice that will assist designers in identifying the design input requirements that are typical of your business. The design output has to reflect a product which is producible or a service which is deliverable. The design input requirements may have been specified by the customer and hence not have taken into account your production capability. The product of the design may therefore need to be producible within your current production capability using your existing technologies, tooling, production processes, material handling equipment,etc. There is no requirement in the standard for designs to be economically producible and therefore unless such requirements are contained in the design input requirements, producibility will not be verified before product is released into production .Having identified the design input requirements, you need to document them in a specification that, when approved, is brought under document control. The requirements should not contain any solutions at this stage, so as to provide freedom and flexibility to the designers. If the design is to be subcontracted, it makes for fair competition and removes from you the responsibility for the solution. Where specifications contain solutions, the supplier is being given no choice and if there are delays and problems the supplier may have a legitimate claim against you.

Clause 8.3.3.1 Product design input

The organization must identify, document, and assess product design input requirements following contract review. These requirements encompass product specifications, including special characteristics, as well as boundary and interface specifications. Product design input should also cover identification, traceability, and packaging considerations. The organization may explore design alternatives and assess associated risks, along with its ability to manage these risks, including through feasibility analysis. Furthermore, product design input should establish targets for meeting product requirements, including aspects such as preservation, reliability, durability, serviceability, health, safety, environmental impact, development timing, and cost. It should also address any relevant statutory and regulatory requirements specific to the destination country identified by the customer. Embedded software requirements may also be included in design inputs. The organization should have a process for incorporating insights gained from past design projects, competitive product analysis, supplier feedback, internal input, field data, and other pertinent sources into current and future projects of a similar nature. Considering design alternatives may involve techniques like the use of trade-off curves.

Use your customer specified APQP reference manual as a good tool for Design and Development planning and control. Product Design and Development is only applicable if you are designated as being design-responsible. Determine (in writing) from your OEM customer if you are designated as being design responsible. You must identify, document and review design inputs requirements for function, performance, safety, regulatory, quality, reliability, durability, life, timing, maintainability, cost, identification, traceability, packaging, special or safety characteristics (from the customer or regulatory body), and other requirements essential to the product. You must have a process to deploy (identify, document, review and use) design input information coming from various sources such as – customer contracts, drawings and specifications; your own organization’s database of previous Design and Development projects; competitor analysis; industry standards; feedback from suppliers; field data.You must review all input requirements for adequacy and completeness. You must ensure that requirements are complete, clear and consistent with each other. The product design input requirements cover various critical aspects of the design process in the automotive industry. These requirements ensure that the design team has a clear understanding of what the product needs to achieve and the considerations they must take into account during the design and development process. Let’s briefly discuss each of the product design input requirements:

1. Product Specifications Including Special Characteristics: Product specifications define the detailed requirements and characteristics that the product must meet. Special characteristics refer to specific features or attributes critical to the product’s performance or safety.
2. Boundary and Interface Requirements: Boundary and interface requirements define the interaction of the product with other systems, components, or external entities. This ensures proper integration and compatibility.
3. Identification, Traceability, and Packaging: These requirements ensure that products are uniquely identified, traceable throughout the production and supply chain, and properly packaged for protection and handling.
4. Consideration of Design Alternatives: The design team should explore and evaluate different design alternatives to select the most optimal and feasible solution.
5. Assessment of Risks and Mitigation Strategies: A risk assessment identifies potential design-related risks and defines strategies to manage or mitigate these risks effectively.
6. Targets for Conformity to Product Requirements: Set clear targets and objectives for product conformity with requirements, encompassing aspects such as preservation, reliability, durability, serviceability, safety, environmental impact, development timing, and cost.
7. Applicable Statutory and Regulatory Requirements: Compliance with relevant laws, regulations, and standards is crucial, especially those specified by the customer’s country of destination.
8. Embedded Software Requirements: In modern automotive products, embedded software plays a significant role. Defining software requirements ensures that it meets performance, safety, and regulatory criteria.

These product design input requirements serve as a foundation for the design team to create products that meet customer expectations, comply with regulations, and are innovative, reliable, and safe. They help guide the entire design and development process, leading to successful and competitive automotive products in the market.

Impact of the results of contract reviews on design input
The standard requires that design input take into consideration the results of any contract review activities. In cases where the contract includes a design requirement, then in establishing the adequacy of such requirements during contract review, these requirements may be changed or any conflicting or ambiguous requirements resolved. The results of these negotiations should be reflected in a revision of the contractual documentation, but the customer may be unwilling or unable to amend the documents. In such cases the contract review records become in effect a supplement to the contract. These records should therefore be passed to the designers so they can be taken into account when preparing the design requirement specification or design brief.

Identifying and documenting statutory and regulatory requirements
The standard requires that the design input requirements include applicable statutory and regulatory requirements. Statutory and regulatory requirements are those which apply in the country to which the product or service is to be supplied. While some customers have the foresight to specify these, they often don’t. Just because such requirements are not specified in the contract doesn’t mean you don’t need to meet them. Statutory requirements may apply to the prohibition of items from certain countries, power supply ratings, security provisions, markings, and certain notices. Regulatory requirements may apply to health, safety, environmental emissions, and electromagnetic compatibility and these often require accompanying certification of compliance. In cases where customers require suppliers to be certified to IATF 16949 it imposes a regulatory requirement on the design process. If you intend exporting the product or service, it would be prudent to determine the regulations that would apply before you complete the design requirement. Failure to meet some of these requirements can result in no export license being granted as a minimum and imprisonment in certain cases if found to be subsequently non compliant. Having established what the applicable statutes and regulations are, you need to plan for meeting them and for verifying that they have been met. The plan should be integrated with the design and development plan or a separate plan should be created. Verification of compliance can be treated in the same way, although if the tests, inspections, and analyses are integrated with other tests etc., it may be more difficult to demonstrate compliance through the records alone. In some cases tests such as pollution tests, safety tests, proof loading tests, electromagnetic compatibility tests, pressure vessel tests, etc. are so significant that separate tests and test specifications are the most effective method.

Reviewing the selection of design input requirements
The selection of design input requirements be reviewed for adequacy. Adequacy in this context means that the design requirements are a true reflection of the customer needs. It is prudent to obtain customer agreement to the design requirements before you commence the design. In this way you will establish whether you have correctly understood and translated customer needs. It is advisable also to hold an internal design review at this stage so that you may benefit from the experience of other staff in the organization. Any meetings, reviews, or other means of determining the adequacy of the requirements should be recorded so as to provide evidence later if there are disputes. Records may also be needed.

Resolving incomplete, ambiguous, or conflicting requirements
The standard requires that incomplete, ambiguous, or conflicting requirements be resolved with those responsible for drawing up these requirements. The review of the design requirements needs to be a systematic review, not a superficial glance. Design work will commence on the basis of what is written in the requirements or the brief, although you should ensure there is a mechanism in place to change the document should it become necessary later. In fact such a mechanism should be agreed at the same time as agreement to the requirement is reached. In order to detect incomplete requirements you either need experts on tap or checklists to refer to. It is often easy to comment on what has been included but difficult to imagine what has been excluded. Ambiguities arise where statements imply one thing but the context implies another. You may also find cross-references to be ambiguous or in conflict. To detect the ambiguities and conflicts you need to read statements and examine diagrams very carefully. Items shown on one diagram may be shown differently in another. There are many other aspects you need to check before being satisfied they are fit for use. Any inconsistencies you find should be documented and conveyed to the appropriate person with a request for action. Any changes to correct the errors should be self-evident so that you do not need to review the complete document again.

Deploying information from previous designs
The standard requires the supplier to have a process to deploy information gained from previous design projects, competitor analysis, or other sources as appropriate for current and future projects of a similar nature. The intent of this requirement is to ensure you don ’t repeat the mistakes of the past and do repeat the past successes. The implication of this requirement is that previous design project deploys the information, whereas it cannot do so without a crystal ball that looks into the future. All you can do is to capture such data in a database or library that is accessible to future designers. A rather old way of doing this was for companies to create design manuals containing data sheets, fact sheets, and general information sheets on design topics — a sort of design guide that captured experience. Companies should still be doing this but many will by now have converted to electronic storage medium with the added advantage of the search engine. Information will also be available from trade associations, libraries, and learned societies. In your model of the design process you need to install a research process that is initiated prior to commencing design of a system, subsystem, equipment, or component. The research process needs to commence with an inquiry such as “Have we done this or used this before? Has anyone done this or used this before?” The questions should initiate a search for information but to make this a structured approach, the database or libraries need to structure the information in a way that enables effective retrieval of information. One advantage of submitting the design to a review by those not involved in the design is that they bring their experience to the review and identify approaches that did not work in the past, or put forward more effective ways of doing such things in the future.

Product design input for competitive product analysis (benchmarking)

Product design input for competitive product analysis, also known as benchmarking, involves gathering relevant data and information about competing products to evaluate and compare their features, performance, and design elements.

Clause 8.3.2.2  Product design skills

Personnel responsible for product design must possess the necessary skills to meet design requirements and should be proficient in relevant product design tools and techniques. The organization should identify the specific tools and techniques applicable to its operations. An example of such skills is the utilization of digitized mathematically based data in the design process.

The competency criteria for personnel with responsibility for design and development must be defined as well as the specific tools and techniques they need to use. They should be competent in using design software such as Catia, Autocad, Solidworks etc, as specified by customers. Keep the copies of certificates handy at the department Software competency means formal training. Learning from friends and having a manual is not considered competent Although not applicable to process design personnel, they should also be familiar with the design software because project may be using the drawings Core tool competency is applicable both for process and product design personnel. Here are some applicable product design tools and techniques commonly used in the automotive industry:

1. Computer-Aided Design (CAD): CAD software allows designers to create detailed 2D and 3D models of automotive components and systems. CAD facilitates visualization, simulation, and rapid prototyping, speeding up the design process and enabling iterative improvements.
2. Computer-Aided Engineering (CAE): CAE tools simulate and analyze the performance of automotive designs under various conditions, such as stress analysis, thermal analysis, and fluid dynamics. CAE helps optimize designs for safety, performance, and durability.
3. Finite Element Analysis (FEA): FEA is a subset of CAE that uses numerical methods to analyze how structures respond to mechanical loads. It aids in evaluating the structural integrity and safety of automotive components.

15. Value Engineering: Value engineering techniques focus on optimizing product features to achieve the best balance between cost, performance, and customer satisfaction.

Strategy to achieve competency in Product design

Ensuring that personnel with product design responsibility are competent and skilled in applicable product design tools and techniques is essential to achieve design requirements and develop high-quality products. The organization can implement several strategies to ensure the competence and skill development of its design personnel:

1. Training and Development Programs: Offer comprehensive training programs that cover product design principles, industry standards, and the use of design tools and techniques. These programs should be tailored to the specific needs of the organization and the roles of the design personnel.
2. Certifications and Qualifications: Encourage design personnel to pursue relevant certifications and qualifications in product design and related fields. Industry certifications can demonstrate their competence and commitment to continuous learning.
3. Cross-Functional Exposure: Provide opportunities for design personnel to work collaboratively with colleagues from different departments, such as manufacturing, engineering, and quality assurance. This exposure enhances their understanding of the entire product lifecycle and encourages knowledge-sharing.
4. Mentorship and Coaching: Establish mentorship programs where experienced designers can guide and support less experienced team members. Regular coaching sessions can help bridge knowledge gaps and foster skill development.
5. Performance Reviews and Feedback: Conduct regular performance reviews to assess design personnel’s progress and competence. Provide constructive feedback and set specific development goals to support continuous improvement.
6. Continuous Learning Culture: Foster a culture of continuous learning within the organization. Encourage design personnel to participate in workshops, seminars, and conferences to stay updated with the latest design trends and technologies.

By implementing these strategies, the organization can build a competent and skilled product design team capable of meeting design requirements, leveraging advanced design tools and techniques, and delivering innovative and high-quality products to the market.

The standard requires the organization to prepare plans for each design and development activity which describe or reference these activities and define responsibility for their implementation. You should prepare a design and development plan for each new design and also for any modification of an existing design that radically changes the performance of the product or service. For modifications that marginally change performance, control of the changes required may be accomplished through your design change process. Design and development plans need to identify the activities to be performed, who will perform them, and when they should commence and be complete. In addition there does need to be some narrative, as charts rarely convey everything required. Design and development is not complete until the design has been proven as meeting the design requirements, so in drawing up a design and development plan you will need to cover the planning of design verification and validation activities. The plans should identify as a minimum:

• The design requirements
• The design and development program showing activities against time
• The work packages and names of those who will execute them (work packages are the parcels of work that are to be handed out either internally or to subcontractors)
• The work breakdown structure showing the relationship between all the parcels of work
• The reviews to be held for authorizing work to proceed from stage to stage
• The resources in terms of finance, manpower, and facilities
• The risks to success and the plans to minimize them
• The controls (quality plan or procedures and standards) that will be exercised to keep the design on course

In drawing up your design and development plans you need to identify the principal activities and a good place to start is with the list of ten steps detailed previously. Any further detail will in all probability be a breakdown of each of these stages, initially for the complete design and subsequently for each element of it. If dealing with a system you should break it down into subsystems, and the subsystems into equipment, and equipment into assemblies, and so on. It is most important that you agree the system hierarchy and associated terminology early on in the development program, otherwise you may well cause both technical and organizational problems at the interfaces. The ten steps referred to previously can be grouped into four phases, a phase being a stage in the evolution of a product or service:

• Feasibility Phase
• Project Definition Phase
• Development Phase
• Production Phase

Planning for all phases at once can be difficult, as information for subsequent phases will not be available until earlier phases have been completed. So, your design and development plans may consist of four separate documents, one for each phase and each containing some detail of the plans you have made for subsequent phases. Your design and development plans may also need to be subdivided into plans for special aspects of the design, such as reliability plans, safety plans, electromagnetic compatibility plans, configuration management plans. With simple designs there may be only one person carrying out the design activities. As the design and development plan needs to identify all design and development activities, even in this situation you will need to identify who carries out the design, who will review the design and who will verify the design. The design and design verification activities may be performed by the same person. However, it is good practice to allocate design verification to another person or organization as it will reveal problems overlooked by the designer. On larger design projects you may need to employ staff of various disciplines, such as mechanical engineers, electronic engineers, reliability engineers, etc. The responsibilities of all these people or groups need to be identified and a useful way of parceling up the work is to use work packages which list all the activities to be performed by a particular group. If you subcontract any of the design activities, the subcontractor’s plans need to be integrated with your plans and your plan should identify which activities are the subcontractor’s responsibility. While purchasing is dealt with in clause 8.4 of the standard, the requirements apply to the design activities. The standard requires that the design and development plans describe or reference design and development activities. Hence where you need to produce separate plans they should be referenced in the overall plan so that you remain in control of all the activities.

Clause 8.3.2.1 Design and development planning

In addition to the requirements given in ISO 9001:2015 clause 8.3.2 Design and development planning, clause 8.3.2.1 states that all relevant stakeholders, including those in the supply chain, participate in the planning of design and development. A multidisciplinary approach typically involves various functions within the organization, such as design, manufacturing, engineering, quality, production, purchasing, supplier management, maintenance, and others as necessary. This approach is applied in areas such as project management, for instance, APQP or VDA-RGA. It encompasses the development and review of risk analyses for product design (like FMEAs), including actions to mitigate potential risks, as well as the development and review of risk analyses for manufacturing processes (e.g., FMEAs), process flows, control plans, and standard work instructions. Activities related to product and manufacturing process design, such as Design for Manufacturing and Design for Assembly, are conducted with consideration for alternative designs and manufacturing processes.

Please click here for ISO 9001:2015 clause 8.3.2 Design and development planning

This must include the Design and Development of both the product as well as the manufacturing process and extends throughout the product program life. The scope of your Design and Development activity must consider all aspects of the product and product realization processes to ensure its conformity to requirements. This includes product identification, handling, packaging, storage and protection during internal processing and delivery to the customer. Product Design and Development sometimes results in new manufacturing processes or changes to existing manufacturing processes. This clause is equally applicable for designing and developing manufacturing processes. Planning must focus on error prevention rather than detection in product as well as manufacturing Design and Development. You must have an overall plan for your design project. Your plan must specify the design and development stages, activities and tasks; responsibilities; timeline and resources; specific tests, validations, and reviews; and outcomes. There are many tools available for planning ranging from a simple checklist to complex software. Use your customer-specific manuals for APQP as a good starting point. The degree and details of planning may vary according to size and length of contract or project, complexity, risk, product life, customer and regulatory requirements, past experience with similar product, etc. You have flexibility in determining the scope of the stages, review, verification and validation required for your product Design and Development projects. Your plan must be dynamic and updated as requirements and circumstances change. You must track progress against your plan at regular intervals or project milestones and update the plan as activity progresses. You must use a multi-disciplinary approach, that includes as needed, other functions (besides design) such as quality, engineering, purchasing, sales, tooling, production, etc.. Your plan must clearly identify these other functions and their specific role and responsibilities regarding the project. Consider including customer and supplier personnel at appropriate stages to do work and review results or progress. Consideration must also be given to the methods of communication and interaction. Inclusion of these controls in your Design and Development plan is one of many effective ways to achieve this. A multi-disciplinary approach has the benefit of applying collective and relevant knowledge and skills of these different functions to carry out or review Design and Development activities. You must use the multi-disciplinary approach for specific activities such as determination of special characteristics, conducting FMEA’s, developing control plans, and plant and facility planning, etc. The Design and Development project plan serves as both a document and a record as it is updated for completion for various activities. Where some or all of the design responsibility is subcontracted or done off-site, then you must ensure that your organization and the subcontractor or off-site location collectively address all the requirements of clause 8.3 with particular coverage of the interfaces between them. You must review all input requirements; review Design and Development progress; verify product design and validate developed product at various stages of your Design and Development process. The nature, frequency and scope of these controls must be defined in your Design and Development plan or other document. You must carry out these controls according to your plan and keep appropriate records. You must identify and document all processes addressing this clause as part of your QMS. For these processes, you must also identify what specific documents are needed for effective planning, operation and control of production activities . These documents may include – contracts; technical drawings and specifications; a documented plan for Design and Development; work instructions; a documented procedure; etc., combined with unwritten practices, procedures and methods. Look at the risks related to your product, processes and resources in determining the nature and extent of documented controls you need to have . Many organizations use various software tools to document their product or process Design and Development plans. Performance indicators (to measure the effectiveness of design and development processes in meeting requirements and achieving quality objectives) should focus on reducing variation in and improving these processes and related use of resources. Indicators may include reduction in – design cycle time; development cycle time; specification errors, omissions; changes; Design and Development costs; etc., as well as measurable improvements in products developed. Here are the key steps involved in design and development planning in IATF:

1. Scope and Objectives: Define the scope of the design and development activities, including the intended purpose of the product, its intended use, and any specific customer requirements or standards that must be met. Establish clear objectives and expectations for the design and development process.
2. Responsibilities: Identify and assign roles and responsibilities for each stage of the design and development process. This includes a cross-functional team that collaborates on design activities, with representatives from engineering, manufacturing, quality, and other relevant departments.
3. Customer Requirements: Gather and analyze customer requirements, expectations, and feedback to understand the needs of the end-users. These requirements should be documented and used as a basis for the design and development process.
4. Regulatory Compliance: Identify and understand all relevant regulatory and legal requirements that apply to the product. Ensure that the design and development process complies with these requirements and that all necessary certifications and approvals are obtained.
5. Risk Management: Perform a risk analysis to identify potential risks associated with the design and development process. Develop plans to mitigate these risks and address any potential issues that may arise during the product development.
6. Resource Allocation: Determine the resources needed for the design and development process, including personnel, equipment, facilities, and materials. Ensure that the necessary resources are available and allocated appropriately.
7. Timelines and Milestones: Establish a detailed timeline with specific milestones for the design and development process. This will help track progress and ensure that the project stays on schedule.
8. Design Input: Define the design inputs based on customer requirements, industry standards, and other relevant information. These inputs should be specific, measurable, achievable, relevant, and time-bound (SMART) to guide the development process effectively.
9. Design Review: Plan for design reviews at various stages of the development process to assess the progress and verify that the design outputs meet the design inputs. This may include internal reviews and external customer reviews.
10. Verification and Validation: Establish procedures for the verification and validation of the design outputs. Verification ensures that the design meets the specified requirements, while validation confirms that the final product meets the intended use and customer needs.
11. Change Management: Develop a robust change management process to handle any changes to the design and development activities. Changes should be documented, reviewed, approved, and communicated to all relevant stakeholders.
12. Documentation: Maintain comprehensive documentation throughout the design and development process. This includes design plans, specifications, records of design reviews, verification, and validation results, and any other relevant information.
13. Training and Competence: Ensure that all personnel involved in the design and development process are adequately trained and competent to perform their respective tasks. Training records should be maintained and periodically updated.
14. Communication: Establish effective communication channels within the cross-functional team and with external stakeholders, including customers and suppliers. Regular communication ensures everyone stays informed about the project’s progress and any potential issues.
15. Continual Improvement: Implement mechanisms to capture lessons learned and feedback from completed design and development projects. Use this information to drive continual improvement in future design processes.

By following these steps, organizations can create a structured and efficient design and development planning process that aligns with the requirements of IATF 16949 and leads to the successful development of automotive products.

Multidisciplinary approach in Design and Development planning

A multidisciplinary approach in design and development planning involves bringing together experts and professionals from organization’s design, manufacturing, engineering, quality, production, purchasing, supplier, maintenance, and other appropriate functions to collaboratively work on a project. In the context of the automotive industry, this approach is essential as modern vehicles are complex systems that require expertise from different fields to create successful products. Here’s how a multidisciplinary approach can be applied to design and development planning in the automotive sector:

1. Cross-Functional Teams: Assemble a team that includes engineers, designers, manufacturing experts, quality assurance specialists, marketing professionals, and other relevant stakeholders. Each team member brings their unique perspective, knowledge, and skills to the project.
2. Understanding Customer Needs: Different disciplines can provide valuable insights into customer needs. For example, market research specialists can gather customer feedback, while designers can translate those needs into tangible product features.
3. Innovation and Creativity: A multidisciplinary team fosters an environment where innovative ideas and creative solutions can emerge. Engineers, designers, and other team members can collaborate to find novel ways to meet customer requirements and industry challenges.
4. Early Identification of Issues: A diverse team can identify potential issues and challenges from different angles. This early identification enables proactive problem-solving and reduces the likelihood of costly design flaws later in the process.
5. Integrated Design Process: With experts from various fields collaborating, the design process becomes more integrated and holistic. Decisions consider the implications on manufacturing, quality, and other aspects of the product’s lifecycle.
6. Improved Problem-Solving: When challenges arise during the design and development process, a multidisciplinary team can pool their expertise to find comprehensive solutions.
7. Effective Communication: Communication is enhanced as team members with different backgrounds learn to understand each other’s terminologies and perspectives. This reduces misunderstandings and ensures a smoother workflow.
8. Optimizing Trade-offs: In automotive design, there are often trade-offs between various factors such as performance, cost, safety, and sustainability. A multidisciplinary team can better analyze these trade-offs and make informed decisions.
9. Prototyping and Testing: The expertise of various team members can contribute to designing effective prototypes and conducting relevant tests to validate the product’s performance and safety.
10. Regulatory Compliance: In the automotive industry, meeting regulatory requirements is crucial. With diverse expertise, the team can address safety and compliance considerations effectively.
11. User-Centric Design: A multidisciplinary team can create products that are more user-centric by considering different aspects of the user experience, such as ergonomics, aesthetics, and functionality.
12. Continuous Improvement: The diversity of perspectives in the team allows for continuous improvement, where lessons learned from previous projects can be incorporated into future designs.

In conclusion, a multidisciplinary approach in design and development planning is instrumental in developing successful automotive products. By harnessing the expertise of professionals from different disciplines, companies can create innovative, safe, and customer-focused solutions that meet the ever-evolving demands of the automotive industry.

Project management such as APQP or VDA-RGA in Design and development

Project management methodologies such as Advanced Product Quality Planning (APQP) and VDA-RGA (German Association of the Automotive Industry – Requirements for Project Management in the Automotive Industry) play a crucial role in the design and development process of automotive products. These methodologies help ensure that projects are effectively planned, executed, and controlled, leading to the successful development of high-quality products. Let’s explore each of these project management methodologies:
