The history of ISO 9001 - a success story

DQS - Germany's First Management System Certification Body

The founding of DQS in 1985 marked an important milestone. On February 1, 1985 – five months before the first drafts of the ISO 9000 family were published – DQS (Deutsche Gesellschaft zur Zertifizierung von QualitätsSicherungssystemen mbH) began its operations. This made DQS the first management system certification body in Germany and the third worldwide. The organization was established on the initiative of the German Society for Quality (DGQ) and the German Institute for Standardization (DIN). In 1991, DQS became the first certification body in Germany to receive accreditation for ISO 9001/2/3 from the then TGA GmbH – now the German Accreditation Body (DAkkS).

More than 40 years after the shared history of ISO 9001 and DQS began, we remain committed to quality and continue to carry the "Q" in our name – even though quality assurance systems have long since evolved into management systems.

1987

The ISO 9001, ISO 9002, and ISO 9003 standards were officially published as models for quality management systems based on 20 quality system elements. In Germany, they were adopted as DIN ISO standards:

• DIN ISO 9001 - A model for demonstrating quality assurance in all areas of an organization, including design, development, production, installation, and servicing.
• DIN ISO 9002 - A model for demonstrating quality assurance in production and installation.
• DIN ISO 9003 - A model for demonstrating quality assurance through final inspection and testing.

The introduction of this new international family of standards led to the withdrawal of numerous national and industry-specific standards. The goal of international harmonization had been achieved. In many countries, the standards were also officially recognized as an essential element of legally required conformity assessment procedures.

Industry associations that had previously resisted the new standards began to embrace them and even developed more stringent sector-specific versions for industries such as automotive, medical devices, aerospace, and food. To this day, the ISO 9000 family serves as the foundation for numerous industry-specific management system standards, including IATF 16949 for the automotive industry and ISO/TS 22163 for the rail sector.

1994 - The First Minor Revision

ISO standards are reviewed at regular intervals, typically every five to six years. These reviews determine whether a standard still reflects the current state of the art, requires revision, or should be withdrawn altogether. This systematic review process ensures that the requirements remain relevant to the conditions in which organizations operate. The history of ISO 9001 is therefore also a story of continuity and reliability.

The first revision of ISO 9001 took place in 1994. However, it introduced only minor changes, primarily of an editorial and terminological nature.

2000 - A Major Turning Point: From Quality Assurance to Quality Management

ISO 9001:2000 marked a fundamental transformation. The revision consolidated ISO 9001, ISO 9002, and ISO 9003 into a single standard and fundamentally reshaped the concept of quality management.

The shift from QA (Quality Assurance) to QM (Quality Management) during the 1990s, together with the introduction of the process approach, represented two of the most significant milestones in the history of ISO 9001. The change in terminology reflected a broader shift in practice - from ensuring quality to actively managing it throughout the organization.

As a result, ISO 9001 became firmly established as a responsibility of top management - the level at which organizational leadership and strategic direction are defined. Long before the process approach was formally incorporated into ISO 9001, DQS had already adopted process-oriented auditing. This pioneering approach helped open the door to quality management certification for many service organizations.

The revised standard was also written in clearer, more accessible language, making it easier to apply across all industries, particularly in the service sector. Substantively, the previous structure based on 20 quality system elements was replaced by a process-oriented approach. The revision also introduced a stronger focus on customer satisfaction and on managing an organization's core processes.

Requirements that were not applicable (such as design and development) could now be excluded, provided they met the criteria for "permissible exclusions" defined in Clause 7 of the standard. The modern understanding of quality management and its role in business practice was reflected in the Eight Quality Management Principles.

2008 - Clarifications Without Structural Changes

ISO 9001:2008 - The fourth edition of ISO 9001 was published in 2008. Most of the changes were intended to improve usability by clarifying existing requirements. The overall structure, strategic direction, and core requirements of the standard remained essentially unchanged.

2015 - High Level Structure

ISO 9001:2015 - The latest major revision, published in September 2015, marked another important chapter in the history of ISO 9001. The standard was aligned with the High Level Structure (HLS), which has served as the common framework for all ISO management system standards since 2012. It establishes a harmonized structure, common core text for management system requirements, and standardized terms and definitions.

Key changes included:

• The introduction of the context of the organization, addressing both internal and external factors that influence an organization.
• Consideration of relevant interested parties and their needs and expectations.
• A stronger emphasis on the responsibility and leadership of top management.
• The adoption of a risk-based approach, replacing the previous concept of preventive action.
• The introduction of organizational knowledge as a recognized organizational resource.

2026: The Next Revision - What Can We Expect?

In summer 2023, the ISO/TC 176 SC2 Technical Committee approved a further revision of ISO 9001:2015. Publication is scheduled for September 2026. Although the content may still change before the final version is released, the draft DIN EN ISO 9001:2025-09 already provides valuable insights into the expected direction of the revision.

Key areas of focus include stronger emphasis on leadership, quality culture, and ethical behavior, a clearer distinction between opportunities and risks, as well as the consideration of digitalization, climate change, and supply chain resilience.

40 Years Serving Business: DQS and ISO 9001

The history of DQS is closely linked to the history and development of ISO 9001. In 2025, DQS celebrated its 40th anniversary – and if the publication of the first draft of the standard in 1985 is considered its starting point, the same milestone can, in a way, also be applied to ISO 9001.

The standard has come a long way. To this day, successful organizations rely on modern quality management systems to safeguard their success in the marketplace. The insights gained from our annual audits make a significant contribution to this by continuously improving an organization's structures and processes.
