AIAG and VDA

The AIAG (Automotive Industry Action Group) publishes automotive industry standards and offers educational conferences and training to its members, including the Advanced Product Quality Planning (APQP) and Production Part Approval Process (PPAP) quality standards. These documents have become a de facto quality standard in North America that must be complied with by all Tier I suppliers.

Increasingly, these suppliers are now requiring complete compliance from their suppliers, so that many Tier II and III automotive suppliers now also comply.

The German Association of the Automotive Industry or VDA (Verband der Automobilindustrie e. V.) is a German interest group of the German automotive industry for both automobile manufactures and automobile component suppliers.

The VDA represents carmakers including BMW, Volkswagen and Mercedes-Benz but also counts foreign suppliers and foreign-owned carmakers like Opel

among its members.

The VDA published a series of standards and recommendations. Among those is the German Quality Management System (QMS) for the automotive industry. The fourth edition was issued in December 1998, and became mandatory for all German car makers and their
suppliers on April 1, 1999.
