ISO/TS 16949 is an ISO technical specification aimed at the development of a quality management system that provides for continual improvement, emphasizing defect prevention and the reduction of variation and waste in the automotive industry supply chain. It is based on the ISO 9001 standard and the first edition was published in June 1999 as ISO/TS 16949:1999. It was prepared by the International Automotive Task Force (IATF) and the “Technical Committee” of ISO. It harmonizes the country-specific regulations of quality Management systems. About 30 percent of the more than 100 existing automobile manufacturers affiliate the requirements of the norm but especially the large Asian manufacturers have differentiated, own requirements for the quality management systems of their corporate group and their suppliers. ISO/TS 16949 applies to the design/development, production and, when relevant, installation and servicing of automotive-related products. The requirements are intended to be applied throughout the supply chain. For the first time vehicle assembly plants will be encouraged to seek ISO/TS 16949 certification.
