PPAP is an acronym for Production Parts Approval Process, which is a formal method of production part approval from a manufacturer to its customer that was developed by and is widely used in the automotive industry, and has since found wide usage in many other industries as well. It was developed by Automotive Industry Action Group (AIAG), a non-profit organization created to develop recommendations and a framework for the improvement of quality in the North American automotive industry – AIAG guidelines, such as those for PPAP, have become the standard in the automotive industry and are often required by OEMs and Tier-1 suppliers.
In the automotive industry, OEMs and their suppliers work through formal design and development processes to establish engineering specifications for each product and component produced, and PPAP is an industry standard to ensure that the engineering design and product specifications are met through prototyping and dimensional layouts, that production processes have adequate statistical capability to ensure consistent quality, and that measurement systems are repeatable with results that are reproduceable between operators. The purpose of PPAP is as follows:
PPAP is important to make sure that correct specifications are used every time a new component is developed, or any time a significant change is made to the existing component by which it is manufactured. This process gives OEMs and customers confidence in the products being supplied by ensuring that the supplier is meeting the manufacturing and quality requirements of the parts being produced and sanctions quality output and assurance. This confidence is gained through the collection of records and data that consititute the 18 elements of a PPAP, with varying elements being supplied to the customer in the formal PPAP submission depending on the level of PPAP required. These 18 elements are:
Following PPAP can provide multiple benefits such as maintaining design integrity, evidence to process stability, improve the quality of component parts, assurance that parts would conform to customer requirements, preventing the use of unapproved parts, and reducing the cost of poor quality, etc. The final element, the PSW, is a warrant that is submitted to the customer with the package that they can sign following the review of the submission to confirm that they have observed adequate evidence that specifications and capability, capacity, measurement system, and other requirements have been met to ensure consistent delivery of quality products – the signed warrant allows the supplier to begin supplying product to the customer.
Since PPAP is required anytime a new part of change to an existing part or process is being planned and may be requested by a customer at any time during the life of a product, maintaining a quality system that develops and documents all of the requirements of a PPAP submission, no matter if you have been asked to deliver one, is a must.
