Product approval process — PPAP (IATF only)
Plain-language summary
Before shipping, products and processes must pass the customer's approval process (typically PPAP) — and you must apply the same discipline to your suppliers before their parts enter your approved product.
What the clause is really asking
Conform to the customer-defined approval procedure: documentation package (FMEA, control plan, MSA, capability, dimensional results, material certs etc. per required level), customer disposition before volume supply, and approval of your purchased products before your own submission. Records retained per 7.5.3.2.1.
What auditors look for
Auditors sample current parts and ask for the approved PPAP at the current engineering level: customer approval evidence (PSW signed/portal status), package contents per required level, supplier PPAPs feeding into it. Production at a newer change level than the approved PPAP is a classic major.
Typical evidence
PPAP packages with signed PSWs; submission level evidence; supplier PPAP records; PPAP-to-engineering-change reconciliation.
How to comply — recommendations
Keep a PPAP status register: part, change level, approval date, level, expiry conditions. Re-check it on every engineering change (link 7.5.3.2.2) — the register catches the drift that audits punish.
Common nonconformities
Production at a change level newer than the approved PPAP; PSW missing or unsigned; supplier parts never PPAP'd; package incomplete for the claimed level.
