Quality Glossary Definition: ISO 9000 series standards

A set of international standards on quality management and quality assurance developed to help companies effectively document the quality system elements to be implemented to maintain an efficient quality system.

The ISO 9000 Series is a set of international standards for quality management and quality assurance. The standards were developed to help companies effectively document the elements they need to maintain an efficient quality system. They are not specific to any one industry.

ISO 9000 can help a company satisfy its customers, meet regulatory requirements, and achieve continual improvement. But it’s a first step, many quality professionals will tell you, the base level of a quality system, not a complete guarantee of quality.
