Production Part Approval Process (PPAP)
PPAP packages combine dimensional data, material records, and process documentation to secure customer approval for ongoing production.
An approved First Article Inspection report is a core element of most PPAP levels.
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
Any process change—equipment moves, tooling updates, supplier shifts—may require resubmission.
Monitoring RPN tracking from FMEA reviews helps prioritise updates.
Streamlining PPAP with KaizenQ
KaizenQ stores PPAP documents alongside inspection templates, providing a single source of truth for auditors.
Version history and approvals are tracked so teams know which submission is current.
- PPAP demonstrates a supplier’s readiness for serial production.
- Process changes often require revalidation and updated submissions.
- KaizenQ keeps PPAP artifacts organised and accessible.
