Simple definition
A Change Advisory Board reviews proposed IT changes and advises on their risks, scheduling, business impact, and readiness.
Purpose and use
A CAB, Change Advisory Board, brings relevant perspectives to assessing selected changes and their cross-service effects.
How does it work?
It contributes technical and business views of risk, dependencies, scheduling and resources under the chosen governance model.
Example and verification
For a complex change, provide concrete evidence so review produces useful decisions or preparation conditions.
Points to watch
A CAB is not automatically mandatory for every modification or the universal authority for all changes.
In short
Its value depends on proportionate decisions and advice with an explicit role in the change process.
