Production Part Approval Process (PPAP) is a valuable tool for establishing confidence in component suppliers and their production processes. In today’s competitive manufacturing environment controlling cost and maintaining a high level of quality have become vital to a company’s success. Increasing costs of equipment, materials and labour combined with expanding world markets have resulted in an increase of outsourced parts. Therefore, it has become imperative to provide quality parts that meet the customer’s requirements the first time and every time.

What is PPAP?

PPAP defines the approval process for new or revised parts, or parts produced from new or significantly revised production methods. The PPAP process consists of 18 elements that may be required for approval of production level parts. Not all the elements are required for every submission. There are five generally accepted PPAP submission levels. The resulting PPAP submission provides the evidence that the supplier has met or exceeded the customer’s requirements and the process is capable of consistently reproducing quality parts.

When to perform PPAP

A PPAP is required for any new part submission as well as for approval of any change to an existing part or process. The customer may request a PPAP at any time during the product life.

Why perform PPAP?

The PPAP process verifies that the supplier understands all customer engineering design specifications and requirements and that the process is capable of consistently producing product meeting those requirements during an actual production run at the quoted production rate.
