What is PPAP in the automotive sector?

As against the development of the new product design, PPAP is a structured procedure that give the process plan of manufacturing a component as generalised approved procedure.Once the process plan is defined we can define critical control points for quality checks. By and more PPAP gives room for improvment of manufacturing procedure by addressing the non-conformances and selectively revewing the individual process number that had contributed to the non-conformance. Overall it is documented procedure that gives foresight into the quality requirement of a part during its production phase.

PPAP stands for "Production Part Approval", it's an essential process that keep tracking the new product during the design, producing the samples, getting customers comnents, requirements for inspections; untill approving the pilot run by customer and starting the mass production and regular delivery to the customers.
