The PPAP manual requires detailed documentation on each of the items listed in the PPAP Elements Table
PPAP Elements Table
|2||Engineering Change (note) Documents|
|5||Process Flow Diagram|
|10||Material and Performance Tests|
|11||Initial Process Studies|
|12||Qualified Laboratory Documentation|
|13||Appearance Approval Report|
|14||Sample Production Parts|
|18||Part Submission Warrant (PSW)|
The content of the Manual / Package is determined by the PPAP submission Level.
Level 1- PSW ONLY
Level 2- PSW with product samples and limited supporting data
Level 3- PSW with product samples and complete supporting data
Level 4- PSW and other requirements as defined by the customer
Level 5- PSW with product samples and complete supporting data available for review at the manufacturing location
Critical Elements of the Process Approach
- Process owner exists
- Process is defined
- Process is documented
- Linkages of process established
- Process monitored, analyzed and improved
- Records maintained
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:
- The client’s requirements have been understood.
- The product supplied meets those requirements.
- The process (including sub suppliers) is capable of producing conforming product.
- 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.
PPAP is the confirmation that the product meets the customer requirements for series production.
The status of these deliverables drives the rating (Red/Yellow/Green/Complete/NA) status for each element.
