PPAP
PPAP should prove that the defined production process can repeatedly make conforming product.
What this topic covers
What PPAP evidence is supposed to demonstrate.
PPAP is strongest when the submission is the output of a controlled process—not a documentation exercise performed after the fact.
- Keep drawing revision, process flow, PFMEA and Control Plan synchronized.
- Verify measurement-system and capability evidence against the characteristics that matter.
- Close deviations and open actions before treating approval as process readiness.
A clean submission cannot compensate for an unstable or poorly defined production process.
