A history of ISO 9001

ISO 9001 has come a long way since its formulation in the defence industry over five decades ago. Originally created to ensure quality of products supplied to the MOD and continuity in the procedures carried out by its workers, the concept of quality assurance was then championed by the UK government in 1966. Unfortunately at this time suppliers were undergoing assessments from a wide range of their customers and the idea of further assessment was not a popular one.

Timeline of events

    • 1969 – Government committee submit a report recommending suppliers be assessed against a generic standard of quality assurance.
    • 1971 – BSI (British Standards Institute) publish BS 9000 the first UK standard for quality assurance for use in the electronics industry
    • 1974 – BS 5179 “Guidelines for Quality Assurance” is published. Suppliers can now demonstrate quality assurance to customers through third-party assessment.
    • 1979 – BS5750 is published as the culmination of meetings between BSI and industry throughout the ’70s. It is agreed that this document will replace key industry’s own standards.
    • 1987 – Initial ISO 9000 certification standard is published as ISO 9000:1987. It had the same structure as BS5750 and was more suited to manufacturing with emphasis on conformance to procedures rather than overall management processes.
    • 1994 – The standard undergoes its first revision and becomes ISO 9000:1994. Emphasis is placed on creating quality assurance by seeking to identify and prevent possible deviations before they occur. However like its predecessor many companies took the requirements very literally, created a lot of substantiate paperwork and got too caught up in the bureaucracy of it all.
    • 2000 – The standard is revised again to ISO 9001:2000. This time the standard aimed to focus predominantly on the concept of process management in an attempt to create ‘a documented system’ as opposed to ‘a system of documents’. Emphasis was now on continually improving processes and monitoring customer satisfaction. The following eight core principles were introduced:1. Improved consistency with traceability
      2. Enhanced customer focus
      3. Focused leadership
      4. The involvement of people
      5. A system approach to management
      6. Continual improvement
      7. A factual approach to decision making
      8. Mutually beneficial supplier relations
  • 2008 – ISO 9001:2008 is published, clarifying existing requirements and improving compatibility with other management system standards.

 

  • 2015 – Published September 2015 and is a major overhaul of the standard. The main change being the adoption of Annex SL. Annex SL is the new standard platform for all management standards and will allow easier integration in future.  The standard has come into line with other standards as it is now a risk based standard. The standard requires that you assess the needs and expectations of “interested parties” and that you describe the “context” of your organisation. This is a move towards better business reliance and continuity although not explicit it is implied and makes good business sense. 
  • 23 February 2024 – ISO 9001:2015 Amendment 1 is published, adding climate-change considerations to the organisation's context and the requirements of interested parties.
  • 16 September 2026 – ISO 9001:2026, the sixth edition, is published. It improves clarity and usability, strengthens the focus on leadership and quality culture, and clarifies the distinction between risks and opportunities.
