PPAP defines the general product approval requirements along with manufacturing and bulk materials.

The purpose of PPAP is to determine whether the client’s requests in various specification forms are properly understood by the manufacturer and whether the manufacturing process has the ability for continuous production of the specified products, as described in the specifications at a defined production level (Run and Rate).

Production part approval process


The PPAP documentation consists mostly of the APQP (Advanced Product Quality Planning) results. Therefore, it is true that a well-conceived and implemented APQP provides most of the PPAP documentation. It is then necessary to issue the product quality warranty certificate (PSW and enclose samples from the first serial delivery).

The solution is intended for companies that have to record project activities for product development and also for companies that perform Make to order (MTO).


  • The main advantage of the PPAP report is to avoid the distribution of unauthorized parts and materials from the production line.
  • The PPAP report enables easier and timely detection of problems, errors and delays in the initial stages of the production process, which means lower costs and less wasted time.
  • The PPAP process improves the relationship between the manufacturer and the customer by ensuring that the specifications and production plans are clear and understandable to both parties. The PPAP also ensures easy and effective customer monitoring of the process.
