PPAP, or Production Part Approval Process, is a standardized process used in the automotive industry to ensure that parts and components meet specified quality and performance requirements. The process involves a series of steps that must be completed before a part or component can be approved for production. These steps include creating a design record, completing a design review, creating process flow diagrams and control plans, conducting process capability studies, and performing a series of inspections and tests to verify that the part or component meets all required specifications. PPAP is an important quality control tool that helps ensure that parts and components are consistently manufactured to the highest standards.
