Overview
The part submission warrant is the one page that summarises a PPAP submission. It names the part, the reason for submission, the submission level and the results, and carries the supplier's signed declaration that the evidence shows the part meets every requirement.
How it works
The supplier completes the warrant once the evidence for the submission is ready, at the level the customer has asked for. The level decides which other elements are sent with the warrant and which are kept on file for review.
The customer reviews the submission and records the result, usually full approval, interim approval for a limited time or quantity while open items close, or rejection. A new warrant is submitted when a change to the part or its process requires a new approval.
Examples
- A warrant for a new automotive microcontroller at the level the customer requested.
- A resubmitted warrant after a change of assembly site.
- An interim approval recorded while one capability study is completed.
- A warrant listing the drawing revision and the parts measured.
Why it matters
APQP and PPAP engineers, quality engineers and customer quality engineers use the warrant as the record of approval. It marks the end of product and process validation and the start of series shipments in the APQP lifecycle.
It matters most to: APQP and PPAP Engineer, Automotive Quality Engineer (IATF 16949), Customer Quality Engineer (Automotive)
Common confusions
- Not the same as PPAP
- PPAP is the whole approval process and its evidence package; the warrant is the signed summary at its head.
