1. Design Documentation
A part drawing that is usually provided by the customer. Every feature on the part drawing must be ballooned (or bubbled) to correspond with the inspection results. This includes print notes, standard tolerance notes and specifications, and anything else that is relevant to the design of the part.
Learn more abouthow to create a ballooned part drawing for PPAP.
Why include a copy of the part drawing in your PPAP? It shows your customer you have a copy of the part drawing and ensures you are both discussing the same part.
2. Engineering Change Documentation
A document that shows the detailed description of the change, usually called an "Engineering Change Notice". This document is only required if there is a change.
3. Customer Engineering Approval
This approval is usually the engineering trial with sample production parts performed by the customer. A "temporary deviation" is often required to send parts to the customer before the PPAP is complete. Your customer may require other additional engineering approvals.
4. Design Failure Mode and Effect Analysis (DFMEA)
Design Failure Mode and Effect Analysis (DFMEA) is an application of the Failure Mode and Effects Analysis (FMEA) that is specific to the design stage. The DFMEA allows the design team to document what they predict about a product's potential failures before completing a design and use this information to mitigate the causes of failure.
5. Process Flow Diagram
The Process Flow Diagram shows all the steps required in the manufacturing of the part. It should include all of the main steps in the processing of the part including incoming components, measuring, and inspection. The Process Flow Diagram should match the control plan and the Process Failure Mode and Effects Analysis (PFMEA) and also includes the flow of non-conforming materials and parts.
6. Process Failure Mode and Effects Analysis (PFMEA)
Process Failure Mode and Effects Analysis (PFMEA) evaluates each step in the production process to indicate what could go wrong during the fabrication and assembly of each part.
7. Control Plan
The Control Plan mirrors the PFMEA (Process Failure Mode and Effects Analysis) and provides more details on how potential issues are checked in the incoming inspection, assembly process, or during the inspection of the finished part.

8. Measurement System Analysis Studies
The Measurement Systems Analysis is a study itself and will conform to the customer's relevant ISO or TS standard. Typically it includes the Gauge R&R (Gauge Repeatability and Reproducibility) for the criticalcharacteristics and a confirmation that gauges used to measure these characteristics are calibrated.
9. Dimensional Results
A list of every dimension on the ballooned part drawing and measurement results. This list includes the product characteristic, specification, measurement results, and assessment showing if the dimension "passed" or "failed". Typically a minimum of 6 pieces are reported per product. Learn more abouthow to create a PPAP Dimensional Results Report.
10. Records of Material / Performance Tests
A summary of all tests that have been performed on the part.The summary should document any pass or fail inspection results. It should be signed off by the customer and the supplier to show that all required tests have been done and any additional data for tests have been submitted.
11.Initial Process Studies
Generally, this includes SPC (Statistical Process Control) charts for critical characteristics. These studies demonstrate that the critical processes are stable and are ready to begin the process validation builds.
12. Qualified Laboratory Documentation
Includes all of the industry certifications for any lab that was involved in completing validation testing.
13. Appearance Approval Report (AAR)
The Appearance Approval Report verifies that the customer has inspected the final product and it meets all the required appearance specifications for the design. The report includes color, textures, fit (gaps between parts), etc.
14. Sample Production Parts
A picture of the production parts is included in the PPAP documentation along with the location where the parts are stored.
15. Master Sample
A sample part that is signed off by the customer and supplier. The master part is normally used to train operators on subjective inspections such as visual or for noise.
16. Checking Aids
Checking aids are used by production and are a detailed list of all the tools used to inspect test or measure parts during the assembly process. This aid will list the part, describe the tool, and have the calibration schedule for the tool.
17. Records of Compliance with Customer Specific Requirements
This section of the PPAP requirements is where each customer lists their own specific requirements for the PPAP process.
18. Part Submission Warrant (PSW)
ThePart Submission Warrantis a summary of the entire PPAP submission and specifies:
- The drawing numbers and revisions
- Part information
- Test results
- Material declarations numbers
- Any deviations from earlier elements
