Applicable to all parts and commodities, the Production Part Approval Process (PPAP) principles help to reduce delays and non-conformances during part approval by providing a consistent approval process.
The PPAP is a file that accompanies the initial samples. It is an essential stage in the customer-supplier relationship.
The AIAG handbook outlines the process to demonstrate engineering design and product specifications are met by the supplier’s manufacturing process and sets out the rules for the composition, submission and development of the PPAP file.
