PPAP Documents
On this site, you will find lots of information on building or updating a complete PPAP. This site includes PPAP information, different levels of PPAP that can be requested, examples of submissions, training providers and a checklist to make sure your Production Part Approval Process is correct.
From initial design to full production approval
The Production Part Approval Process (PPAP) is a structured method used to ensure that manufacturing processes consistently produce parts that meet all customer engineering and quality requirements. Most commonly applied within the automotive and advanced manufacturing supply chains, PPAP provides confidence that suppliers can deliver conforming parts at scale, every time.
By documenting design intent, process controls, and validation results, PPAP reduces risk before mass production begins. It creates a clear, auditable trail that demonstrates compliance, capability, and readiness. Helping both suppliers and customers avoid costly issues later in the production lifecycle.
A few topics we discuss with our experienced guests:
PPAP Documents List
A complete PPAP submission is made up of multiple documents that collectively demonstrate product conformity, process capability, and manufacturing readiness. Below is an overview of the key PPAP elements and their purpose within the approval process.
| PPAP Document | Summary | View More |
|---|---|---|
| Part Submission Warrant (PSW) | Formal declaration that all PPAP requirements have been met and the part is approved for production. | View more |
| Design Records | Drawings and specifications defining the approved design requirements for the part. | View more |
| Authorised Engineering Change Documents | Records of approved changes to design or process specifications. | View more |
| Engineering Approval | Customer approval where full PPAP submission is not required. | View more |
| DFMEA | Identifies and mitigates potential failures related to part design. | View more |
| Process Flow Diagram | Visual map of the manufacturing process from start to finish. | View more |
