The standard requires that Verification of job set-ups and after shutdown whenever a set-up is performed and that job instructions be available for set-up personnel or there is a planned or unplanned shutdown. Job set-ups relate to changes in tooling, equipment, materials, shifts, personnel, etc. You must determine the importance of set-ups in terms of time taken and risks related to product quality, in determining the extent of set-up verification, methods used and details of work instructions made available to set-up personnel. Tooling FMEA’s provide very useful input to determine this. Verification of job set-ups may include – data on and comparison of the last series (quality records, corrective actions); completeness of equipment and documentation for production, inspection and testing; responsibilities for release after set-up; disposition of pre-launch or set-up scrap; comparisons of last piece with specified requirements and first piece of new run, etc. Include job set-up controls in your control plans. In setting up a job prior to commencing a production run, you need to verify that all the requirements for the part are being met. You will therefore need job set-up instructions so as to ensure each time the production of a particular part commences that the process is set up against the same criteria. In addition, process parameters may change whenever there is material changeover, a job change, or if significant time periods elapse between production runs. Documentation verifying job set-ups should include documentation to perform the setup and records that demonstrate that the set-up has been performed as required. This requires that you record the parameters set and the sample size and retain the control charts used which indicate performance to be within the central third of the control limits. These records should be retained. The organization should to use statistical methods of verification during job set-up. You will need to produce more than one part to verify that the process is stable. You need to form a sample large enough to take statistical measurement. If the measurements taken on the product fall within the central third of the control limits then the set-up can be approved – if not, then adjustments should be made and further samples produced until this condition is achieved.
In the automotive industry, a planned shutdown refers to a scheduled interruption of production or manufacturing operations within a facility. This planned downtime is often scheduled well in advance to carry out essential maintenance, upgrades, retooling, or other necessary tasks. During a planned shutdown, production lines are intentionally stopped to perform tasks that are difficult or impossible to execute during regular operation. The goal of a planned shutdown is to ensure the long-term efficiency, reliability, and safety of the manufacturing processes and equipment.Planned shutdowns offer several benefits to automotive manufacturers. They allow time for preventive maintenance, which helps prevent unexpected breakdowns and reduces the risk of costly production delays. Additionally, these scheduled breaks provide an opportunity to implement process improvements, upgrade machinery, or incorporate new technologies into the production line. By carrying out such activities during planned shutdowns, automotive manufacturers can optimize their operations and enhance overall productivity.On the other hand, an unplanned shutdown, also known as an unplanned outage or unexpected downtime, refers to an unscheduled interruption of production due to unforeseen events or issues. These events can include equipment failures, supply chain disruptions, power outages, natural disasters, or unforeseen emergencies. Unplanned shutdowns can lead to significant financial losses, reduced productivity, and delays in meeting customer demands.Automotive manufacturers strive to minimize the occurrence of unplanned shutdowns through proactive maintenance practices, robust contingency plans, and risk management strategies. Regular inspections, condition monitoring, and predictive maintenance techniques are employed to identify potential equipment failures or weaknesses before they escalate into major issues. Additionally, strong supplier relationships and well-structured logistics systems help mitigate supply chain disruptions that could lead to unexpected downtime.Both planned and unplanned shutdowns are crucial aspects of the automotive industry. Planned shutdowns allow manufacturers to maintain and improve their production facilities, while efforts to minimize and manage unplanned shutdowns are critical to ensure continuous and efficient operations. Striking the right balance between planned and unplanned downtime is vital for automotive manufacturers to optimize production, enhance quality, and remain competitive in the dynamic automotive market.

Statistical method for Verification
The statistical methods of verification, particularly for first-off/last-off part validation, aim to ensure that the manufacturing process is stable, consistent, and capable of producing parts within the specified tolerances. These methods involve comparing the first part produced (first-off) and the last part produced (last-off) in a production run to assess the process’s variation and consistency. Here’s how each step of the verification process works:
- First-off/Last-off Part Validation:
- First-Off Part: The first part produced during a production run is referred to as the “first-off” part. This part is usually inspected and verified to ensure that the production process is correctly set up and capable of producing parts within the required specifications.
- Last-Off Part: The last part produced during a production run is known as the “last-off” part. It is essential to inspect and verify the last-off part to assess whether the process remained stable throughout the production run.
- Comparison of First-Off and Last-Off Parts:
- First-off parts should be retained and compared with the last-off parts produced in the same production run. This comparison helps identify any variations that may have occurred during the production process.
- If the first-off and last-off parts show consistent dimensions and meet the required specifications, it indicates that the production process is stable and capable of maintaining the required quality throughout the run.
- Retaining Last-Off Parts for Subsequent Runs:
- The last-off parts from the current production run should be retained and used as references for subsequent runs of the same job or product. These parts can be compared with the first-off parts in the next run to assess process consistency over time.
- By comparing the last-off parts from different runs with the corresponding first-off parts, manufacturers can monitor any changes or trends in the production process’s performance.
- Statistical Process Control (SPC): SPC involves using statistical techniques to monitor and control the production process. Control charts are commonly used to analyze data from first-off and last-off parts to identify variations and trends.
- Process Capability Analysis: This analysis assesses whether the production process is capable of meeting the specified tolerances. Process capability indices like Cp, Cpk, Pp, and Ppk can be calculated and compared for the first-off and last-off parts.
- Six Sigma: Six Sigma methodologies can be applied to measure and improve process performance, aiming to minimize variations and defects.
By following these statistical methods of verification for first-off/last-off part validation, manufacturers can ensure that their production processes are stable, consistent, and capable of meeting quality requirements. These practices help identify potential issues early on, leading to improved product quality and reduced variability in the manufacturing process.
Records of process and product approval
Records of process and product approval following set-up and first-off/last-off part validations are critical documentation that demonstrates the successful completion of these verification processes.
