2. Production Part Approval Process (PPAP)
What is PPAP?
Production Part Approval Process (PPAP)
The purpose of PPAP is to determine if all customer engineering design record and specification requirements are properly understood by the Suppliers and that the manufacturing process has the capability to produce product consistently meeting these requirements during an actual production run at the quoted production rates.
Key Take Away:
