Preventive action is an essential component of IATF 16949, the automotive quality management standard. It focuses on proactively identifying and addressing potential issues to prevent their occurrence or recurrence. Preventive actions aim to minimize risks, improve process performance, and enhance product quality. Here are key aspects of preventive action in IATF 16949:
- Risk Assessment and Analysis: Preventive actions begin with a thorough risk assessment and analysis. Organizations identify potential risks and analyze their likelihood, severity, and potential impacts on product quality and customer satisfaction. This analysis helps prioritize risks and determine appropriate preventive actions.
- Proactive Approach: IATF 16949 promotes a proactive approach to preventive action. Organizations are expected to identify and address potential issues before they result in non-conformities or quality problems. Proactive measures help prevent problems from occurring, reducing the need for corrective actions and minimizing the associated costs and disruptions.
- Root Cause Analysis: Preventive actions involve conducting root cause analysis to identify the underlying causes of potential issues or risks. Organizations investigate the factors that could lead to non-conformities, defects, or quality issues. By addressing the root causes, organizations can implement targeted actions that prevent the recurrence of similar problems.
- Process Improvement: Preventive actions often focus on improving processes to minimize the occurrence of potential issues. Organizations identify areas for process enhancement, such as optimizing process parameters, implementing error-proofing techniques (poka-yoke), or upgrading equipment. Process improvements aim to eliminate or reduce the factors that could contribute to problems.
- Training and Competence Development: Preventive action includes providing training and competence development programs for employees. Organizations ensure that employees possess the necessary skills and knowledge to perform their tasks effectively. Training programs address potential gaps, enhance employee capabilities, and promote a culture of continuous improvement and proactive problem-solving.
- Change Management: Preventive action is closely linked to change management processes. Organizations assess the potential risks associated with changes in products, processes, or the quality management system. This assessment helps identify preventive actions that need to be implemented alongside the changes to mitigate or eliminate associated risks.
- Monitoring and Measurement: Organizations establish systems to monitor and measure key process indicators and performance metrics. By regularly monitoring and analyzing data, organizations can identify trends, deviations, or early warning signs of potential issues. This proactive monitoring enables timely implementation of preventive actions to avoid non-conformities and quality problems.
- Documentation and Record-Keeping: Organizations maintain documentation of preventive actions taken. This documentation includes the identification of potential issues, the corresponding preventive measures implemented, and the evaluation of their effectiveness. By documenting preventive actions, organizations can track their implementation, monitor outcomes, and demonstrate compliance with IATF 16949 requirements.
- Continuous Improvement: Preventive action is an integral part of the culture of continuous improvement promoted by IATF 16949. Organizations continually evaluate the effectiveness of preventive actions, learn from experiences, and refine their preventive action processes. Lessons learned from preventive actions feed into ongoing improvement initiatives, contributing to enhanced product quality and customer satisfaction.
By integrating preventive actions into their quality management systems, organizations can reduce risks, enhance process performance, and prevent quality problems. Implementing a proactive approach, conducting root cause analysis, improving processes, providing appropriate training, and continuously monitoring performance contribute to effective preventive action in compliance with IATF 16949.
IATF 16949:2016 Clause 6.1.2.2 Preventive action
The organization must determine the actions to eliminate the causes of potential nonconformities to prevent their occurrence which must be appropriate to the severity of the potential issues. The organization must establish process to lessen the impact of negative effects of risk which includes determining potential nonconformities and their causes, Evaluating the need for action to prevent occurrence of nonconformities, Determining and implementing action needed, Documented information of action taken, reviewing the effectiveness, Utilizing lessons learned to prevent recurrence in similar processes.
Corrective action is action taken to eliminate the cause of a detected nonconformity to prevent recurrence, whereas preventive action is action taken to eliminate the cause of a potential nonconformity or other undesirable situation, to prevent occurrence. Sources of information for finding potential QMS nonconformities include – analyses of data (see clause 8.4); audit results; cost of quality reports; quality records; service reports; supplier performance; customer satisfaction feedback; FMEA’s; management review records; lessons learned from past experience; SPC charts and analyses. You must have a documented procedure for your preventive action process which must address basically all of the explanation points and tips covered under the corrective action process. While preventing potential QMS nonconformities is our focus for ISO 9001 and IATF 16949, it might be very useful to think of preventive action in a wider context, i.e. the entire business. Think in terms of actions needed to prevent – loss of market share; loss of product profitability; loss due to lack of product diversity; loss of business opportunities due to lack of capacity, inadequate or older facilities, production equipment, technology or information systems; loss of key or competent personnel; inadequate business financing; inadequate staffing, etc. These issues may have far more serious consequences than QMS issues. Consider a process that involves developing a business plan covering these issues, based on – gathering relevant research data on these issues; use of appropriate risk evaluation and management methods; developing proactive strategies and action; monitoring and reviewing performance against the business plan. This would constitute the ultimate preventive action process. Consider using a Pareto analysis to organize and rank the dollar value impact of the data on the issues listed above in order to: Determine the magnitude of risks and effects on the organization and Prioritize preventive on these issues as they are all important and may need significant amounts of resources to address them. Performance indicators to measure the effectiveness of the preventive action process may include – reduction in cycle time for preventive actions, problem re-occurrence, open preventive actions, costs; and improvement in QMS productivity.
Some examples of preventive actions commonly implemented in the automotive industry to prevent quality issues and improve overall performance:
Design for Manufacturability (DFM) Analysis: Conducting DFM analysis during the product design phase to identify and address potential manufacturing challenges and issues upfront. This helps prevent design-related problems and ensures smooth production processes.
Robust Incoming Material Inspection: Implementing thorough inspection and testing procedures for incoming materials and components to identify any quality issues or deviations early on. This prevents the use of defective or substandard materials in the manufacturing process.
Regular Equipment Maintenance and Calibration: Establishing a proactive equipment maintenance schedule to ensure machinery and tools are operating optimally. Conducting regular calibrations and preventive maintenance helps prevent equipment failures, reduce downtime, and maintain consistent quality.
Statistical Process Control (SPC): Utilizing statistical process control techniques to monitor critical process parameters and detect any variations or trends that may impact product quality. Implementing SPC allows for early identification of potential issues and enables corrective actions to be taken promptly.
