Simple definition
Change management governs the assessment, approval, implementation, and review of modifications to IT services and infrastructure.
Purpose and use
Change management controls service modifications to manage risk and business effects.
How does it work?
It organizes assessment, decision authority, preparation, implementation and follow-up according to change type and risk.
Example and verification
Before execution, define intended outcomes, validation, dependencies and a suitable rollback or recovery approach.
Points to watch
Not every change requires identical procedure. A preauthorized standard change and a major modification need proportionate handling.
In short
The process should enable controlled evolution with responsibility and evidence appropriate to risk.
