PPAP

From Wikipedia, the free encyclopedia

PPAP is an acronym for Production Part Approval Process.

The Production Part Approval Process is used in the automotive supply chain to establish confidence in component suppliers and their production processes, by demonstrating that:-

"....all customer engineering design record and specification requirements are properly understood by the supplier and that the process has the potential to produce product consistently meeting these requirements during an actual production run at the quoted production rate."

[edit] PPAP Approval

The result of the PPAP process 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 approval by the supplier and customer. The form that summarizes this package is called PSW (Part Submission Warrant). The approval of the PSW indicates that the supplier responsible person (usually the Quality Engineer) has reviewed this package and that the customer has not identified any issues that would prevent its approval.

The documentation on the PPAP package is closely related to the Advanced Product Quality Planning process (APQP) used during the design and development of new vehicles and component systems to reduce the risk of unexpected failure due to errors in design and manufacture. The PPAP manual is published by the Automotive Industrial Action Group (AIAG), [www.aiag.org] and specifies generic requirements for obtaining PPAP approvals. Additional customer specific requirements may be imposed by particular clients (vehicle manufacturers) and incorporated in the purchasing contracts. Details of 'customer specific' requirements may be found on the AIAG website http://www.aiag.org or supplier portals provided by the vehicle manufacturers.

Suppliers are required to obtain PPAP approval from the vehicle manufacturers whenever a new or modified component is introduced to production, or the manufacturing process is changed. Obtaining approval requires the supplier to provide sample parts and documentary evidence showing that:

1) The clients requirements have been understood
2) The product supplied meets those requirements
3) The process (including sub suppliers) is capable of producing conforming product
4) The production control plan and quality management system will prevent non-conforming product reaching the client or compromising the safety and reliability of finished vehicles

Production Part Approval Process (PPAP) may be required for all components and materials incorporated in the finished product, and may also be required if components are processed by external sub-contractors.
