What is Model Change Control?
Model change control is the process for reviewing, approving, testing, documenting, and deploying changes to an AI model or its surrounding system. It is important because uncontrolled changes can alter performance, risk profile, compliance status, or legal claims about the system.
In Depth
In practice, model change control covers updates to weights, prompts, thresholds, features, retraining, vendor model swaps, and changes to post-processing or guardrails. Compliance teams rely on it to preserve traceability, ensure appropriate testing before release, determine whether a change triggers revalidation or reassessment, and maintain an audit trail of who approved what and why.
This control is closely aligned with ISO 27001 change management concepts and with ISO/IEC 42001 AI management practices, where documented governance over AI lifecycle changes is expected. It is also consistent with the EU AI Act’s lifecycle-oriented approach to risk management, technical documentation, monitoring, and substantial modification considerations.
