ISO 9001 is the internationally recognized standard for Quality Management Systems (QMS). It is the most widely used QMS standard in the world, with over 1.1 million certifications issued to organizations in 178 countries.

The ISO 9001 standard provides a framework and a set of principles that promote a common-sense approach to managing organizations, ensuring consistent satisfaction of customers and other stakeholders. ISO 9001 certification forms the basis for highly effective processes and teams capable of delivering high-quality products or services over time.

The 2015 version of the ISO 9001 quality standard follows a common structure provided by Annex SL. This version makes ISO 9001:2015 more compatible with other management systems, such as ISO 14001, thus facilitating the integration and enhancing the efficiency of connected management systems.
