ABOUT ISO/TS 16949 The ISO/TS 16949 standard is a technical specification defining quality system requirements for the design and development, production, installation and servicing of automotive-related products. The standard encourages the use of a process approach that is aimed at improving process efficiency and is designed to achieve the highest levels of product quality, productivity, competitiveness, and continual improvement. ISO/TS 16949 was jointly developed by the International Automotive Task Force (IATF) members and approved by the International Organization for Standardization. IATF members include leading automotive manufacturers and their trade associations. This standard, together with any customer-specific requirements, defines the quality system requirements used in the automotive supply chain. ISO/TS 16949 is based on ISO 9001:2000, but it includes a number of additional specific quality requirements. ABOUT TOWER SEMICONDUCTOR LTD.
