ISO 42001: understanding the standard dedicated to AI

Published in December 2023 by ISO, ISO/IEC 42001 is the first international standard to define a governance framework for artificial intelligence systems. Before it, organizations deploying AI had no equivalent to ISO 27001 for security or ISO 9001 for quality. It introduces the AI management system, or AIMS, covering the full lifecycle: design, training data, deployment, human oversight, continuous improvement.

The companies concerned are not limited to model vendors. Any organization that integrates generative AI into its processes, including through third party tools such as a conversational assistant or a recommendation engine, is exposed to the governance, risk management and transparency requirements the standard describes.

Audits generally cover AI governance (roles, responsibilities, steering committee), data management (quality, bias, traceability), AI specific risks (hallucination, model drift, dependency on a single vendor) and human oversight of automated decisions.

The standard is still young, and the number of bodies accredited to deliver certification in Europe remains limited, which stretches out both the timeline and the cost of an audit. It also does not replace the EU AI Act, which has been coming into force in stages since 2024: ISO 42001 is a voluntary governance approach, while the AI Act imposes legally enforceable obligations. For a company just starting to structure its AI governance, drawing on the standard's domains without pursuing immediate certification is, in most cases, enough to make real progress.
