Implementing ISO 42001 in 90 Days

ISO 42001 Implementation AIMS 90-day plan AI governance
TL;DR

A pragmatic 90-day path stands up core AIMS scaffolding: scope, policy & roles, risk register, controls & testing, and assurance loop. Day-to-day, reuse your existing management-system backbone (from ISO 27001 if present) and bolt on AI-specific risk taxonomy, change gates, evidence capture, and review cadence. Download the detailed 90-day checklist CSV for actionable tasks with owners and success criteria.

Section 01 // Key Facts

Key Facts

5 facts documented

  • ISO 42001 requires documented scope, responsibilities, risk mgmt, lifecycle controls, and review.

    [1]

  • Existing ISMS processes can host AIMS processes to reduce duplication. [Inference from ISO 42001 + ISO 27001 catalogs]

    [1]

  • Risk taxonomy must include AI-specific hazards (e.g., prompt injection, misuse).

    [1]

  • Continual improvement requires metrics and CAPA.

    [1]

  • Evidence is mandatory: test plans, logs, approvals, reviews.

Section 02 // Implementation

Implementation Steps

4 steps
  1. 01

    Days 1–30: Scope & policy; role assignments; initial risk register → scope file, policy, RACI, risk log.

  2. 02

    Days 31–60: Controls & tests; logging; change gates; supplier checks → test logs, drifts, tickets.

  3. 03

    Days 61–90: Management review; internal audit; CAPA; finalize metrics → review minutes, CAPA.

  4. 04

    Always: Version everything; keep an evidence index.
