QS9000

A document, distributed by the AIAG, which defines the fundamental quality system expectations of subscribing companies (including DaimlerChrysler, Ford, Freightliner, General Motors, Mack Trucks, Navistar International, PACCAR, and Volvo GM Heavy Truck). ISO 9001:1994 Section 4 forms the foundation for QS-9000.

QS9000 is a quality standard developed by a joint effort of the "Big Three" automakers, General Motors, Chrysler and Ford. It was introduced to the industry in 1994. It has been adopted by several heavy truck manufacturers in the U.S. as well. Essentially all suppliers to the automotive industry need to implement a QS9000 system.

The standard is divided into three sections with the first section being ISO 9001 plus some automotive requirements. The second section is titled "Additional Requirements" and contains system requirements that have been adopted by all three automakers - General Motors, Chrysler and Ford. The third section is titled the "Customer Specific Section" which contains system requirements that are unique to each automotive or truck manufacturer.

On December 14, 2006, all QS9000 certifications were terminated and was superseded by ISO/TS 16949.
