Change management and approval gates

Medium effortCovered by ISO 27001: StrongSatisfies 17 obligations in 10 policies

What it means

  • New AI products and changes to existing ones pass through defined gates before reaching customers: idea, risk assessment, build or buy, testing, approval, release.
  • AI-specific changes need control too: retraining, new training data, prompt or system instruction edits, switching model version or vendor, changing thresholds, adding tools to an agent.
  • Each gate has an approver and evidence. High risk changes need sign-off from someone independent of the builders.
  • There is a way to roll back or withdraw a model quickly if it misbehaves.

Why it matters

  • RBI FREE-AI says every AI-enabled product should go through product approval with AI-specific checks by a team independent of developers.
  • Many AI incidents come from "small" changes: a prompt edit or a vendor's silent model upgrade.
  • Proposed legislation (the AI Ethics and Accountability Bill 2025) floats withdraw-and-fix powers; a tested rollback path is good preparation.

Checklist

  1. Define AI product approval gates and who approves at each, scaled by tier.
  2. Add AI change types to the change management policy (retrain, data change, prompt change, model or vendor version change, threshold change).
  3. Require risk reassessment (SC-AI-005 AI risk assessment) and retesting (SC-AI-015 Pre-deployment testing and validation) for material changes.
  4. Version-control prompts, configurations and models; record which version is live.
  5. Require vendor notice of model changes in contracts and treat them as changes.
  6. Keep a documented rollback plan and test it.
  7. Update model and system cards on each change.

Evidence examples

  • Product approval record for the AI-based collections tool, with sign-offs from risk, compliance and an independent reviewer.
  • Change tickets for model retraining with linked test results and approval.
  • Git history or prompt registry showing versioned system prompts.
  • Rollback test record (date, time to roll back, result).

Common pitfalls

  • Prompt changes made directly in production with no ticket.
  • Vendor model upgrades accepted automatically.
  • Approval gate run by the build team alone.
  • No rollback path because the old model version was deleted.

ISO/IEC 42001

  • 6.3 Planning of changes
  • A.6.1.3 Processes for responsible design and development of AI systems
  • A.6.2.5 AI system deployment

ISO/IEC 27001

  • A.8.31 Separation of development, test and production environments
  • A.8.32 Change management

  • CC3.4
  • CC8.1

Key takeaways

  • Treat prompts, data, thresholds and vendor model versions as changes that need approval.
  • Strong reuse from ISO 27001 change management (A.8.32, A.8.31) and SOC 2 CC8.1; add AI change types and an independent approval for high risk.
  • Always keep a tested rollback path.
