Quality Assurance Our quality policies and philosophy of continuous improvement help us shape our customers’ product experience. All GM suppliers are required to be ISO 9000 certified—a set of international standards on quality management and quality assurance. Likewise, all manufacturing operations that require International Organization for Standardization (ISO) 9001:2015 certification by certain regions/countries have done so. Globally, we have transitioned to the new ISO 9001:2015 standard, which is aligned with the most recent trends. Fifty-two operations have completed the transition and certification through 2021. We have nine component plants certified to the International Automotive Task Force (IATF) 16949 standards. We also maintain a Global Manufacturing System that incorporates all ISO and IATF requirements, guides quality aspects of our business and has more rigorous standards, in some cases, than external ones. A focus of our quality assurance programs is “initial quality,” which refers to vehicle issues that customers may experience in the first months of ownership. In recent years, customer convenience features, such as user-friendly infotainment systems, seat comfort or placement of knobs and handles, have emerged as top initial quality issues rather than component-related issues. We measure our performance in this area through a key metric: J.D. Power Initial Quality Study (IQS) Problems Per Hundred. Vehicle Quality and Satisfaction Recognitions J.D.
