Definition and context
PPAP combines dimensional results, material records and process evidence for customer approval of production parts. It is common in automotive supply chains. Confirm submission requirements with the customer.
What a PPAP includes
Typical submissions contain design records, engineering change documents, DFMEA and PFMEA results, measurement system analysis, capability studies, and control plans.
Suppliers also provide samples and appearance approvals where applicable.
Maintaining PPAP compliance
Equipment moves, tooling changes or supplier changes may require notification and resubmission under the applicable rules. Confirm the submission level and customer-specific requirements rather than assuming every change needs the same package.
Where this term fits in the workflow
Production Part Approval Process (PPAP) is usually shown in the process control and risk.
Terms that help factories monitor variation, validate capability, and reduce risk before defects escape.
