ISO 42001 audit structure
Stage 1 (documentation review)
- Auditor reviews AIMS documentation (typically 1-3 days)
- Confirms scope, applicability, key documents present
- Identifies gaps before Stage 2
- Typically 2-3 weeks before Stage 2
Stage 2 (operational assessment)
- Auditor onsite (or remote) verifies AIMS operating effectively
- 3-10 days depending on scope + system count
- Walkthroughs, interviews, evidence sampling
- Conclusion: certification recommended (subject to non-conformity closure) or not
Surveillance audits
- Annual; reduced scope vs initial
- Typically 1-3 days
- Focus on high-risk areas + changes since prior audit
Re-certification (year 3)
- Full audit; similar to initial
- Typically every 3 years
AIMS audit-prep sprint
4-week sprint (mature AIMS, surveillance audit)
Week 1: Internal audit + gap analysis
Week 2: Remediation + AI inventory refresh
Week 3: Documentation review + walkthrough rehearsal
Week 4: Auditor onsite
8-week sprint (Stage 1 + Stage 2 initial certification)
Weeks 1-3: AIMS documentation completion (Annex A controls coverage)
Weeks 4-5: Stage 1 audit + gap closure
Weeks 6-7: Stage 2 operational evidence prep + mock walkthroughs
Week 8: Stage 2 audit
ISO 42001 clauses + Annex A controls
Clauses (4-10): management system
| Clause | Topic |
|---|---|
| 4 | Context of the organization |
| 5 | Leadership |
| 6 | Planning (including AI risk + AI objectives) |
| 7 | Support (resources, competence, awareness, communication, documentation) |
| 8 | Operation (AI lifecycle, supplier relationships) |
| 9 | Performance evaluation (monitoring, internal audit, management review) |
| 10 | Improvement (nonconformity, continual improvement) |
Annex A controls (10 areas)
| Annex A area | Topics |
|---|---|
| A.2 | Policies related to AI |
| A.3 | Internal organization |
| A.4 | Resources for AI systems |
| A.5 | Assessing impacts of AI systems |
| A.6 | AI system lifecycle |
| A.7 | Data for AI systems |
| A.8 | Information for interested parties |
| A.9 | Use of AI systems |
| A.10 | Third-party relationships |
Critical audit areas
AI Inventory + Impact Assessments
| Item | Evidence | Common gap |
|---|---|---|
| Complete AI system inventory | Inventory document | Shadow AI not captured |
| AI Impact Assessment (AIIA) per system | Per-system AIIA | Skipped for "low-risk" systems |
| AIIA reviewed periodically | Review records | One-time only |
| Risk classification of systems | Per system | Not documented |
AI Policy + Governance
| Item | Evidence | Common gap |
|---|---|---|
| AI policy approved + dated | Signed policy | Not signed / stale |
| AI ethics principles | Documented principles | Generic; not actionable |
| AI governance body | Charter / minutes | Not formalized |
| Roles + responsibilities | RACI | Not defined |
AI Lifecycle Management (Annex A.6)
| Item | Evidence | Common gap |
|---|---|---|
| AI development lifecycle defined | Process documentation | Not formalized |
| Data quality controls | Per system | Generic only |
| Model validation procedures | Per system | Validation skipped |
| AI system testing | Per system | Inadequate testing |
| Deployment controls | Per system | No controls |
| Operational monitoring | Per system | Drift not monitored |
| Decommissioning procedures | Per system | Not defined |
Data Governance (Annex A.7)
| Item | Evidence | Common gap |
|---|---|---|
| Data sources documented | Per system | Vague |
| Data quality assessed | Quality metrics | Not measured |
| Data lineage tracked | Documentation | Untracked |
| Sensitive data protection | Controls | Insufficient |
Third-party AI (Annex A.10)
| Item | Evidence | Common gap |
|---|---|---|
| Third-party AI inventory | List | Incomplete |
| Vendor due diligence for AI | Per vendor | Generic IT only |
| Contract terms for AI vendors | AI-specific clauses | Standard MSA only |
Clarify First
Before running the audit-prep, confirm these inputs. If any is unknown or vague, ASK — do not assume:
- Audit type and stage — Stage 1 documentation review, Stage 2 operational, surveillance, or internal (sets sprint length and whether the focus is documentation or operational evidence)
- AIMS maturity — mature system vs building from gaps (picks the 4-week vs 8-week sprint)
- AI systems in scope — which systems and how many (drives the AIIA count and Annex A coverage)
Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the readiness assessment.
Quick start
- Run readiness score:
python3 scripts/aims_readiness_score.py --config aims-controls.yaml - Check AIIA per system:
python3 scripts/ai_impact_assessment_checker.py --aiia system-aiia.yaml - Pick sprint length based on score
- Execute sprint per references/iso42001-aims-readiness-checklist.md
Common AIMS audit findings
- AI inventory incomplete — shadow AI not captured
- AIIA missing for systems that look "small" but have impact
- AI lifecycle process not implemented (designed only)
- Data governance generic — not AI-specific
- Performance monitoring missing — drift not detected
- AI policy stale — written before current AI deployment
- Third-party AI vendors not assessed
- Continual improvement not evidenced
Tooling
