What is PPAP Documentation?

In today’s era in an Automobile/Aerospace Industry, every supplier has to be assessed of his capabilities on the way he carries out his work. He is required to provide proof of how each process functions and its difficulties as documented evidence to its client for verification to ensure long-term business. That’s why the term Production Part Approval Process (PPAP) Document came into existence. Every OEM’s goal is to have a trustworthy/reliable supplier and PPAP enforces that requirement.

Due to its positive results, other industries like defense, consumer goods, medical, electronics have been quick to adopt PPAP.

This in-depth document is like a formal certification/approval by the supplier that quality is being taken the utmost care and any kind of defects is being avoided.

PPAP is important for –

  • The OEM’s to validate supplier’s performance based on quality, quantity and its effectiveness under a production process.
  • The suppliers, as they would know what are the customers (OEM) requirement and specifications for a product.
  • Both the customer and the supplier to maintain a perfect document on all the necessary information on a part which can be referred anytime.

When PPAP is required?

PPAP is mostly required when a change to an existing part or process is being planned or initiated, new parts, etc. Whenever such a change takes place, it is considered a critical activity for an Automobile/Aerospace Industry. To address such change, PPAP is considered a valuable tool for establishing confidence in component suppliers and their production process.
