ISO 9000 is a family of standards for quality management systems. ISO 9000 is maintained by ISO, the International Organization for Standardization and is administered by accreditation and certification bodies. Although the standards originated in manufacturing, they are now employed across a wide range of other types of organizations. A “product”, in ISO vocabulary, can mean a physical object, or services, or software.
ISO 9001 is a series of documents that define requirements for the Quality Management System Standard. ISO 9001 is one of the documents in this set; it contains the actual requirements an organization must be in compliance with to become ISO 9001 Registered.ISO 9001:2000 is the current version of the Standard. It was revised in the year 2000. Past versions of ISO 9000 included ISO 9002 and ISO 2003, but those are no longer in use. Companies are now only Registered to ISO 9001.
