ISO 42001 Implementation Guide
Step-by-step AI Management System implementation and certification pathway.
What Is ISO 42001?
ISO/IEC 42001:2023 is the first international management system standard for AI. It follows the same Annex SL structure as ISO 9001/27001 and is required for the EU AI Act high-risk compliance pathway.
16-24 Week Implementation Phases
| Weeks 1-2 — Gap Analysis | Scored gap report and prioritised action plan |
| Weeks 3-5 — AIMS Design | Scope, policy, objectives and governance structure |
| Weeks 6-8 — Risk Management | Risk assessment methodology and treatment plans |
| Weeks 9-12 — Controls | Operational controls and evidence for every clause |
| Weeks 13-15 — Internal Audit | Audit against ISO 42001; address non-conformities |
| Week 16+ — Certification | 2-stage audit with accredited certification body |
Evidence Required Per Clause
- Clause 4 Context: stakeholder register, regulatory scope, AI system inventory
- Clause 5 Leadership: signed policy, documented roles, management review records
- Clause 8 Operation: lifecycle records, test documentation, deployment approvals
- Clause 9 Evaluation: monitoring records, internal audit reports, management minutes with AI KPIs

Frequently Asked Questions
How do I implement ISO 42001, step by step?
Indigonix runs a 16–24 week pathway: a scored gap analysis (weeks 1–2), AIMS design covering scope, policy and governance structure (weeks 3–5), risk assessment methodology and treatment plans (weeks 6–8), operational controls and clause-level evidence (weeks 9–12), an internal audit against the standard (weeks 13–15), then the two-stage certification audit with an accredited body (week 16+).
What is ISO/IEC 42001 and why does it matter?
ISO/IEC 42001:2023 is the first international management system standard for artificial intelligence. It follows the same Annex SL structure as ISO 9001 and ISO 27001, and it is required for the EU AI Act high-risk compliance pathway — which is why organisations increasingly treat it as the backbone of AI governance rather than a certificate.
Where do I start: gap analysis or documentation?
Start with the gap analysis. The most common failure is writing policies before knowing which AI systems exist, who owns them and what data they touch. A scored gap report turns that unknown into a prioritised action plan, and every document produced afterwards has a purpose and an owner.
What evidence does each clause require?
Clause 4 (Context): stakeholder register, regulatory scope, AI system inventory. Clause 5 (Leadership): signed policy, documented roles, management review records. Clause 8 (Operation): lifecycle records, test documentation, deployment approvals. Clause 9 (Evaluation): monitoring records, internal audit reports and management minutes containing AI KPIs.
How does ISO 42001 relate to the EU AI Act?
They are complementary, not duplicates. ISO 42001 gives you the management system — governance structure, risk process, controls and evidence. The EU AI Act gives you the legal obligations — classification, transparency, human oversight and documentation. An AIMS built to ISO 42001 is the most efficient way to produce the evidence the AI Act expects.
