APQP gate connection
Gate G4 completion — prepare the production-readiness decision
This phase consolidates accepted product and process evidence into a practical readiness review. Confirm the PPAP status, manufacturing-line readiness, supplier capacity, quality controls, open-risk closure and launch responsibilities. Prepare the next APQP review by making remaining actions explicit, owned and time-bound.
- PPAP deliverables accepted according to applicable approval rules
- Plant process, workstation, team and quality-loop readiness assessed
- Supplier delivery capacity and logistics readiness confirmed
- Remaining deviations, risks and actions have an approved disposition
Use the approved APQP grid and applicable customer procedure for exact acceptance criteria; this public guide is a practical summary, not a substitute for controlled requirements.
