APQP is a quality plan, but it is also a project development plan. Since it is a plan, its time starting point is from the official start of the project to the end of PPAP. After normal mass production, it is concluded that there are no other problems and the development project can be closed. The performer is the whole APQP team.
PPAP is the approval procedure of production parts, which is only a link in the whole APQP plan, usually in the second half of the APQP plan and generally the core of the APQP plan.
FMEA/SPC/MSA are all tools of quality management. A friend pointed out that FMEA includes DFMEA and PFMEA, and the import events of these jobs are mostly the early, middle and early stages of APQP. They are mainly related to product design, production technology or technology. This is a prevention plan.
MSA is very simple, that is, check the quantity and tools.
SPC is also very simple, that is, controlling some important parameters and monitoring the stability of their production. If there is a big fluctuation, take immediate measures to correct the process or production process.
MSA, like SPC, was correctly implemented in PPAP stage (there are many factors leading to the premature failure of MSA). Most of the implementers are quality engineers.
Extended data
APQP (Advanced Product Quality Planning) is a structured method to determine and formulate the steps needed to ensure that products meet customer needs.
The goal of the product quality plan is to promote contact with all relevant personnel to ensure that the required steps are completed on time. Effective product quality planning depends on the top management of the company's efforts to achieve customer satisfaction.
Product quality planning has the following benefits:
1. Guide resources to meet customers;
2. Promote the early identification of required changes;
3. Avoid late changes;
4. Provide quality products in time at the lowest cost.
