The Production Part Approval Process (PPAP) is a standardized procedure used in the automotive manufacturing industry to ensure that the production process and produced parts meet specific quality requirements. Originating from guidelines established by the Automotive Industry Action Group (AIAG), PPAP aims to confirm that the suppliers understand the customer's specifications and can consistently produce parts that meet these standards.
The process includes several key elements, such as design documentation, engineering change documents, customer engineering approval, design Failure Mode and Effects Analysis (FMEA), process flow diagrams, and more. By following the PPAP process, manufacturers build trust with their customers and ensure that every component in a vehicle or product adheres to quality standards.
