# Clause 10 — Improvement
22
## ISO/IEC 42001:2023 | Implementation Guide
33

4-
> **Purpose:** An AIMS is not a one-time project — it is a continuously improving system. Clause 10 ensures that when things go wrong (or could go better), the organisation takes structured action to fix problems, prevent recurrence, and systematically improve AI governance over time.
4+
Purpose: Address nonconformities, take corrective action, and drive continual improvement of the AIMS.

## 10.1 — Nonconformity and Corrective Action
2021

21-
### What it requires
22-
When a nonconformity occurs (something does not meet requirements), the organisation must:
23-
1. React to the nonconformity and take action to control and correct it
24-
2. Evaluate the need for action to eliminate the cause
25-
3. Implement any action needed
26-
4. Review the effectiveness of the corrective action taken
27-
5. Update risks and opportunities if necessary
28-
6. Make changes to the AIMS if necessary
29-
30-
### What Counts as a Nonconformity?
31-
32-
| Type | Examples |
33-
|------|---------|
34-
| AIMS process failure | Impact assessment not completed before deployment |
35-
| Policy breach | AI system deployed without required approvals |
36-
| Legal / regulatory breach | AI system violates GDPR or EU AI Act requirement |
37-
| Audit finding | Internal audit identifies missing documentation |
38-
| AI system failure | Model produces discriminatory outputs in production |
39-
| Supplier nonconformity | Third-party AI vendor fails contractual requirements |
40-
| Incident | AI system causes harm to a user or affected person |
41-
| Objective not met | AI governance KPI falls below acceptable threshold |
42-
43-
### Nonconformity and Corrective Action Process
44-
45-
**Step 1 — Detect and Record**
46-
- Source: audit finding, incident report, monitoring alert, stakeholder complaint, management review
47-
- Record the nonconformity: what happened, when, where, who identified it
48-
- Assign a severity level (Critical / Major / Minor / Observation)
49-
50-
**Step 2 — Contain the Immediate Problem**
51-
- Stop the harm or prevent it spreading
52-
- Examples: suspend AI system, disable feature, halt data processing, notify affected users
53-
- Document containment actions taken
54-
55-
**Step 3 — Root Cause Analysis**
56-
- Determine why the nonconformity occurred — not just what happened
57-
- Methods: 5 Whys, Fishbone (Ishikawa) diagram, fault tree analysis
58-
- Example: Model bias detected. Why? Training data was not representative. Why? No data quality check in the development process. Why? The development process did not include this step. Root cause: gap in AI development procedure.
59-
60-
**Step 4 — Plan Corrective Action**
61-
- Define specific actions to address the root cause
62-
- Assign owner and deadline for each action
63-
- Ensure actions are proportionate to the severity of the nonconformity
64-
65-
**Step 5 — Implement Corrective Action**
66-
- Execute the planned actions
67-
- Update documentation, procedures, training as needed
68-
- Communicate changes to relevant staff
69-
70-
**Step 6 — Verify Effectiveness**
71-
- After the correction is implemented, check it worked
72-
- Re-test the AI system, re-audit the process, or monitor the metric
73-
- Close the nonconformity only when the root cause is confirmed eliminated
74-
75-
**Step 7 — Update the AIMS**
76-
- If the nonconformity reveals a systemic issue, update relevant AIMS elements
77-
- Risk register, procedures, training, controls — whatever needs updating
78-
79-

| NCR ID | Date | Source | Description | Severity | Root Cause | Corrective Action | Owner | Deadline | Status | Effectiveness Check |
82-
|--------|------|--------|-------------|----------|-----------|------------------|-------|----------|--------|---------------------|

85-
86-
### AI Incidents and Corrective Action
87-
When an AI system causes harm or near-harm (an incident), the response must be both immediate (contain the harm) and systemic (prevent recurrence). This is why incidents feed directly into the corrective action process.
88-
89-
> Full incident response procedure: see AI-INCIDENT-RESPONSE-PROCEDURE.md in this folder
90-
91-
### Documents Required
92-
- Nonconformity and Corrective Action Register (NCR log)
93-
- Root Cause Analysis Records (per nonconformity)
94-
- Corrective Action Plans
95-
- Effectiveness Review Records
96-
97-

22+
When a nonconformity occurs: react to it, evaluate need for corrective action, eliminate root causes, review effectiveness. See NCR-REGISTER.md and AI-INCIDENT-RESPONSE-PROCEDURE.md.

## 10.2 — Continual Improvement
10025

101-
### What it requires
102-
The organisation must continually improve the suitability, adequacy, and effectiveness of the AIMS.
103-
104-
### The Difference Between Corrective Action and Continual Improvement
105-
106-
| Corrective Action (10.1) | Continual Improvement (10.2) |
107-
|--------------------------|------------------------------|
108-
| Reactive — triggered by a problem | Proactive — not necessarily triggered by a failure |
109-
| Addresses a specific nonconformity | Addresses systemic or strategic improvement opportunities |
110-
| Required when something goes wrong | Required even when things are going well |
111-
| Example: Fix a process that failed | Example: Adopt better bias testing tools before they are required |
112-
113-
### Sources of Improvement Opportunities
114-
- Management review outputs (Clause 9.3)
115-
- Internal audit observations (Clause 9.2)
116-
- AI performance trends (Clause 9.1)
117-
- Stakeholder feedback
118-
- New AI governance best practices or standards updates
119-
- Industry incidents and lessons learned from peers
120-
- Staff suggestions and innovation
121-
- Emerging regulations (e.g., new EU AI Act requirements)
122-
- Technology improvements (better explainability tools, fairness metrics)
123-
124-
### Continual Improvement Framework
125-
126-
Use a Plan-Do-Check-Act (PDCA) cycle applied to your AIMS:
127-
128-
**PLAN:** Identify improvement opportunity, set objectives, plan the change
129-
**DO:** Implement the improvement
130-
**CHECK:** Monitor and measure the results of the improvement
131-
**ACT:** If effective, standardise it across the AIMS. If not, try again.
132-

## The Improvement Loop — How Clause 10 Connects Everything
154-
155-
Clause 10 is the engine that makes the entire AIMS self-correcting and self-improving:
156-
157-
- Clause 9 (Performance Evaluation) identifies what is working and what is not
158-
- Clause 10.1 (Corrective Action) fixes what went wrong
159-
- Clause 10.2 (Continual Improvement) makes things better proactively
160-
- Improvements feed back into Clauses 4-9, updating context, policies, plans, controls, and measurements
161-
162-
This creates a genuine management system — not a static compliance checklist.

## What Auditors Check in Clause 10
181-
- Is there a nonconformity register — and is it actually used?
182-
- Are root cause analyses documented — not just corrective actions?
183-
- Is there evidence that corrective actions were effective?
184-
- Are AI incidents linked to the corrective action process?
185-
- Is there a continual improvement log with proactive improvements (not just reactions to failures)?
186-
- Do improvement actions trace back to management review or audit findings?
187-
- Is there evidence the AIMS is actually getting better over time?
26+
Continually improve the suitability, adequacy, and effectiveness of the AIMS. See CONTINUAL-IMPROVEMENT-LOG.md.
