What is PPAP and How It Can Help You

High QA
January 14, 2022

PPAP is a term you will hear in the manufacturing industry. PPAP stands for Production Part Approval Process (PPAP) and refers to a standard manufacturing method commonly used in the industry to ensure quality and consistency in the production processes. It is part of the APQP checklist. APQP stands for Advanced Product Quality Planning (APQP) and is the manufacturing quality standards maintained by the Automotive Industry Action Group (AIAG).

High QA automates and streamlines the PPAP process for manufacturing quality

The primary purpose of PPAP is to provide evidence that an organization properly understands the specific requirements and the entire customer engineering design record.

It also demonstrates that the manufacturing process can produce products that consistently meet all engineering and quality requirements at the quoted production rate.

All Original Equipment Manufacturer (OEM) suppliers follow this standardized approach to hasten the approval of new and revised parts.

Overall, the PPAP process plays a significant role in improving equipment quality while at the same time lowering the time and expenses it takes in the part approval process.

What Does the PPAP Process Entail?

PPAP comprises 18 elements, but its application depends on customer requirements and the complexity of the parts undergoing manufacturing.

  1. Documenting the Design: This entails the technical drawings and purchase orders.
  2. Engineering Change Notice: It exists if there is a request for amendments to an existing part.
  3. Customer Approval: The customer’s engineering department must give approval.
  4. Design Failure Mode and Effects Analysis (FMEA): A detailed risk assessment that maps out possible loopholes in the design.
  5. Process Flow Diagram: The steps involved in production from start to finish.
  6. Process Failure Mode and Effects Analysis (PFMEA): Outlines possible failures within the manufacturing process.
  7. The Control Plan: Measures to mitigate possible failures.
  8. Measurement System Analysis: A record of the specifications and details of the equipment needed for the production process.
  9. Dimensional Layout Results: A validation check that ensures the technical drawings and the final product match.
  10. Design Verification Plan and Report: Validation records that include all relevant material certifications.
  11. Statistical Process Control (SPC): Statistical quality control documentation of the entire process and the components involved in making the final product.
  12. Qualified Laboratory Documentation: All the certifications from any lab testing.
  13. Appearance Removal Inspection: Approval of the product’s appearance by the customer.
  14. Sample Production Parts: The customer receives the product sample for approval.
  15. Master Sample: The final version of the product for which the customer must sign off.
  16. Checking Aids: All the necessary checks the manufacturer performs during production.
  17. Customer Specific Requirements: Refers to any specific requests the customer makes.
  18. Part Submission Warrant Form (PSW): A summary of everything captured in the PPAP submission, including declaration signatures.

Benefits of PPAP

While the PPAP comprises a long list of elements, it helps to ensure everything is produced according to the manufacturing plan. The process also helps users avoid the use of or distribution of unapproved parts.

It helps certify every crucial process needed to manufacture a part so it meets the engineering and manufacturing standards and quality specifications each time. It puts manufacturers in a position to provide quality output by ensuring they meet the requirements during the production run.


The PPAP process lays clear guidelines for the suppliers to know the expectations they must meet, improving the communication process. Users can also identify suppliers that need more development in the production process.

As a result, PPAP minimizes the risk of failure and enables users to take corrective actions promptly.


The PPAP process makes it easy for customers to detect issues or defects early in the production process. As such, it reduces warranty charges and prevents the costs that emanate from poor quality.

Overall, the process reduces the time and expenses used in the manufacturing process while strengthening the supplier and buyer relationship.
