The Production Part Approval Process (PPAP) provides customers with evidence that:

• Component suppliers have understood their requirements.
• The product meets the customers requirements.
• The production process is capable of consistently producing conforming product.

PPAP is an important part of the product development process, allowing producers to evaluate the components and sub-systems which they receive from suppliers, and establishing confidence in the supplier's management systems. Although individual manufacturers have their own particular requirements, the Automotive Industry Action Group (AIAG) has developed a common PPAP standard as part of the Advanced Product Quality Planning Process (APQP) - and encouraging the use of common terminology and standard forms to document project status.

 

The PPAP process is designed to demonstrate that the component supplier has developed their design and production process to meet the client's requirements, minimising the risk of failure by effective use of APQP.

 

Purpose:

Defines Generic requirements for production for Production Part Approval including production and bulk materials, The purpose of PPAP is to Determine if all customer engineering design record & specification requirements are properly understood by the organisation and that the manufacturing processes as potential to produce the product consistently meeting these requirements during an actual production run at the eliminate the quoted production rate.
