Many customers add their own PPAP requirements on top of the manual; those requirements govern.
What It Covers
The evidence a supplier submits to show that it understands the customer’s engineering requirements and that its production process can meet them consistently at the quoted rate.
Who It Applies To
Suppliers of production and service parts to automotive customers, for new parts, engineering changes and changes to the process, source or location.
Key Requirements
- Eighteen elements, from design records and engineering change documents to the Part Submission Warrant.
- Five submission levels that set which evidence is sent and which is retained.
- Parts taken from a significant production run made with production tooling, processes, and people.
- Customer notification and resubmission when the product or process changes.
What an Auditor Asks to See
- The Part Submission Warrant and the evidence retained behind it.
- Dimensional results for every characteristic on the drawing.
- Your change notification record for the last twelve months.
Where Systems Fall Short
- Process changes made without notifying the customer.
- Retained PPAP evidence that cannot be found when the customer asks.
How QES Helps
PPAP packages assembled and reviewed before submission, and a change notification process that catches changes before they ship.
