ISO 42001 A.5.3: AI System Impact Assessment

What this means

A.5.3 mandates that organizations complete a structured impact assessment prior to AI system deployment. This assessment must evaluate potential consequences across multiple dimensions: discrimination and bias risks, privacy and data protection impacts, security vulnerabilities, safety hazards, transparency and explainability gaps, accountability structures, and broader societal effects. The findings from this assessment directly inform design decisions, implementation conditions, and deployment constraints. This control ensures AI systems are not deployed blindly but rather with documented understanding of risks and mitigation strategies.

How to comply

1. 1.Establish an AI impact assessment process and template tailored to your organization's AI systems and use cases
2. 2.Document the scope, purpose, and intended users of the AI system being assessed
3. 3.Evaluate discrimination risks: identify protected characteristics and test for bias in training data, model outputs, and decision-making
4. 4.Assess privacy impacts: map data inputs, retention periods, and identify exposure to unauthorized access or misuse
5. 5.Analyze security risks: evaluate model robustness against adversarial attacks and data breach scenarios
6. 6.Review safety implications: determine potential harms from incorrect predictions or system failures
7. 7.Evaluate transparency: document model logic, limitations, and how users will understand AI-driven decisions
8. 8.Define accountability: assign ownership for monitoring, incident response, and remediation post-deployment
9. 9.Document societal impacts: consider effects on employment, social equity, and broader stakeholder groups
10. 10.Use assessment findings to establish deployment conditions, monitoring requirements, and design modifications before go-live
11. 11.Maintain impact assessment records as evidence of due diligence and ongoing governance

Evidence auditors look for

• Completed AI impact assessment templates with signed off-by dates for each deployed AI system
• Risk matrices documenting discrimination, privacy, security, safety, and transparency evaluation results
• Design modification logs showing how assessment findings influenced system architecture or training procedures
• Deployment condition documents specifying monitoring, thresholds, and human review requirements based on assessment outcomes
• Bias testing reports and fairness validation studies performed prior to deployment
• Privacy impact analysis and data handling procedures derived from assessment recommendations
• Transparency documentation and user-facing explanations tied to assessment findings
• Stakeholder consultation records showing consideration of societal impacts
• Post-deployment monitoring plans aligned with identified risks from the assessment
• Assessment review and update logs showing reassessment when AI systems or use cases change
