8. MODULES FOR PRODUCTION PART APPROVAL PROCESS (PPAP) IN GENERAL

PPAP is used in the automotive supply chain for establishing confidence in suppliers and their production processes. Actual measurements are taken from the parts produced and are used to complete the various test sheets of PPAP.

The PPAP process is designed to demonstrate that a supplier has developed their design and production process to meet the client’s requirements, minimizing the risk of failure by effective use of APQP. Requests for part approval must therefore be supported in official PPAP format and with documented results when needed.

The purpose of any Production Part Approval Process (PPAP) is to:

  1. Ensure that a supplier can meet the manufacturability and quality requirements of the parts supplied to the customer
  2. Provide evidence that the customer engineering design record and specification requirements are clearly understood and fulfilled by the supplier
  3. Demonstrate that the established manufacturing process has the potential to produce the part that consistently meets all requirements during the actual production run at the quoted production rate of the manufacturing process.

PPAP is a series of documents gathered in one specific location (a binder or electronically) called the “PPAP Package”. The PPAP package is a series of documents which need a formal certification / sign-off by the supplier and approval / sign-off by the customer. The form that summarizes this package is called PSW (Part Submission Warrant). The signature in the supplier certification area of the PSW indicates that the supplier-responsible person (usually the Quality Engineer or Quality Manager) has reviewed this package and that the customer-responsible person (usually a Customer Quality Engineer or Customer Quality Manager) has not identified any issues that would prevent its approbation.
