Last update:

PPAP stands for Production Part Approval Process. This process applies to mass production and is used in the automotive industry. The source of PPAP is the American quality system QS-9000 and the procedures of the production part approval process are described by the AIAG (Automotive Industry Action Group). The Production Part Approval Process is carried out on the basis of 18 specific documents, the most important of which is the Part Submission Warrant (PSW for short).

What is PPAP?

PPAP – as already mentioned – is a process for approving parts for volume production used in the automotive industry. PPAP is a set of requirements that the supplier must meet and present to the customer before starting serial production. The standard PPAP procedure consists of 18 elements. The main goal of the procedure is to submit the required documentation and parts to the customer to confirm the supplier’s production capability.

Production Part Approval Process is the ideal tool to ensure the quality and quantity of delivered parts, from a wide supply chain.

If you want to verify that a delivery will be able to fulfill an order as required – use the Production Part Approval Process.

Who uses PPAP?

Production Part Approval Process is a requirement addressed to suppliers (internal and external) of manufacturing materials, bulk materials, or service parts. The procedure is implemented to obtain evidence that:

  • all customer design requirements, specifications, and other requirements are properly understood by the organization,
  • the production process has the potential to produce a product that meets these requirements.

 

Submission levels

The submission of PPAP documents can have 5 different levels of evidence. The level of evidence is decided by the client.

  • Level 1 – Submit only the Part Submission Warrant – PSW to the customer.
  • Level 2 – Submit warranty to customer with product samples and limited supporting data.
  • Level 3 – Submit warranty to customer with product samples and a complete set of supporting documents to meet specific customer requirements.
  • Level 4 – Submit warranty to customer and in accordance with other requirements specified by customer.
  • Level 5 – Submit to the customer a guarantee with product samples and revised complete supporting data to the organization’s production department. This is the most complicated level.

In practice, most often the customer chooses level 3.

18 elements of the procedure

PPAP consists of 18 well-defined documents. The result of the PPAP procedure shall be a PPAP design flow chart, process flow diagram, control plan, measurement results from first deliveries, material and performance test results, preliminary process test (i.e. process capability analysis – SPC), qualified laboratory documentation, appearance approval report AAR (if applicable), product sample, master sample (from first produced parts), test aids and measurement tools, records of compliance with specific customer requirements, guarantee of submitted part – PSW.

The result of the PPAP procedure shall be the release for serial production granted by the customer.

Growing popularity of PPAP

The automotive industry, through the use of already known statistical and quality tools, has created an 18 element procedure that is successfully used by the automotive industry worldwide. PPAP procedure allows to effectively verify production capacity of suppliers and reduce risk in the supply chain. Aviation industry is also beginning to be interested in PPAP methodology, which proves high effectiveness of this tool.

In the APQP & PPAP course you will learn how to perform the procedure step by step.
