With SRM, supply chain management is defined and integrated. Running changes will be requalified to meet the OEM qualification procedure, but will avoid unnecessary, costly steps. This process provides a step forward for more efficiency during introduction of new products and changes. The product change approval (PCA) procedure takes into account that the ECU is developed in accordance to reliability engineering system (RES) methods and provides a critical view on the announced and implemented changes and the entire application is the basis for further actions. Stepwise it is 1. Supplier selection: Pursue consequently the steps developing a reference matrix on costs, technology, availability, quality logistics and support. This can be done with a radar diagram to identify the best in market. Next is auditing product and process. An assessment of the suppliers is to be performed for final judgment and agreements on quality and reliability figures for delivery. 2. Parts Homologation: Review of specification versus Review of qualification data and perform qualification only for the relevant changes. Assurance in accordance to PPAP level. 3. Technology Assessment Review of qualification and process data Assessment of technology with respect to the automotive application and the ability to meet these requirements. Review measurements and establishments of measurements where required. 4. Assessment of PCH and/or DoD. Review of affects to components, products, systems, and manufacture processes. Completely understood influences to the system. The integrity of the system functionality must be protected, while a balance ts achieved amongst the needs for innovation, differentiation & customer satisfaction, continuity of component supply to meel demand in series production and service, and cost effective implementation.
A sophisticated approach to product change approval (PCA) and discontinue of delivery (DOD) to cope with supply chain management in order to assure the reliability of electronic systems
