ISO 9000 (1994) originally had three QMS models depending on the primary function:

  • ISO 9001:1994 Model for quality assurance in design, development, production,
    installation, and servicing was for companies and organizations whose activities included the creation of new products.

    • Learn about ISO 9001
  • ISO 9002:1994 Model for quality assurance in production, installation, and servicing had basically the same material as ISO 9001 but without covering the creation of new products.
    • Learn about ISO 9002
  • ISO 9003:1994 Model for quality assurance in final inspection and test covered only the final inspection of finished product, with no concern for how the product was produced.
    • Learn about ISO 9003

All of these were combined into ISO 9001:2000, which is now ISO 9001:2008.
