Change Management
Process for managing changes to production environments.
Principles
- Every production change is recorded — no exceptions
- High-risk changes go through CAB (Change Advisory Board)
- Every change has a documented rollback plan
- Maintenance windows are respected except in emergencies
Change types
| Type | Description | Approval | Minimum lead time |
|---|---|---|---|
| Standard | Low-risk change, documented procedure | Technical owner | 24 hours |
| Normal | Medium/high-risk change, new or non-routine | CAB (email approval) | 5 business days |
| Emergency | Emergency hotfix to resolve P1/P2 | CTO / CDO + retroactive approval | Immediate |
