What is the ISO 9000 family of standards on quality management?

The ISO 9000 family consists of the world's best known standard for quality management systems (QMS), ISO 9001, along with a set of supporting standards on quality management, all published by ISO/TC 176 and its subcommittees.

ISO's seven quality management principles

The ISO 9000 standard outlining the fundamental concepts and vocabulary of quality management defines seven principles that all other quality management standards in this family are based on. These principles include a strong customer focus, the active involvement and buy-in of top management, a process-oriented approach, and a commitment to continuous improvement. Further details can be found in ISO’s brochure on quality management principles.
