(PPAP) Product Part Approval Process

Product Part Approval Process (PPAP) is the industry standard that ensures engineering design and product specification requirements are met. Through the PPAP guideline, suppliers and customers understand the requirements to obtain part approval of supplier manufactured parts. Applicable to all parts and commodities, application of these principles reduces delays and non-conformances during part approval.

What specific challenge(s) does this address?

  • Provides understanding of information required to obtain part approval and standardizes the part approval process
  • How to obtain approval of parts/processes after part design changes and/or process changes
  • Ensures part submissions are submitted with proper information and enough data to sustain product conformance
  • Provides a record of part conformance at launch (allows for measurement of drift from origin)
  • Details pertinent design records to ensure traceability of part design status at origin
  • Controls product and process change process, providing an approval outlet for all changes to ensure conformance to the next level assembly/process

What are the benefits of PPAP?

  • Consistent part approval process
  • Assurance parts conform to customer requirements
  • Evidence of process stability
  • Controls product and process change process, providing an approval outlet for all changes to ensure conformance to the next level assembly/process

PPAP is listed in the following OEM Customer Specific Requirements (and is listed in many of the tiered suppliers' Customer Specific Requirements (CSRs)):

  • FCA US
  • Ford Motor Company
  • General Motors
