Change and Release

Change model

• Standard: pre-approved, low risk.
• Normal: requires assessment and approval.
• Emergency: expedited with post-change review.

Pre-approval rules

• Changes must have a rollback plan.
• Security impact assessed for any policy or identity change.
• Maintenance windows applied to production changes.

CAB-lite approach

Cloud changes use a lightweight CAB for speed with control. Approval is delegated to the Service Manager for standardized changes.
