Manage IT roll-back procedures

Trigger: A deployment fails validation, a critical defect is discovered immediately post-release, or a scheduled change window expires before completion.

1. Detect deployment failure or trigger condition
2. Authorize roll-back execution
3. Execute roll-back procedures and scripts
4. Validate system state and data integrity
5. Notify stakeholders of roll-back completion
6. Document roll-back reasons for post-incident review

Outcome: The IT environment is successfully reverted to its last known good configuration and stable state without data loss.
