OVERVIEW

This document establishes procedures for rolling back documentation changes when issues are detected or when rollback is required. It defines rollback triggers, procedures, and communication requirements.

Purpose: To ensure safe and controlled rollback of documentation changes when necessary, minimizing impact and maintaining system integrity.

ROLLBACK PRINCIPLES

Core Principles

1. Safety First: Rollback must be safe and controlled
2. Minimal Impact: Minimize disruption to users
3. Documented: All rollbacks must be documented
4. Communicated: Stakeholders must be notified
5. Reversible: Rollback should be reversible if needed

Rollback Categories

Automatic Rollback:

• Critical errors detected
• System failures
• Data corruption
• Security breaches

Manual Rollback:

• User request
• Management decision
• Compliance requirement
• Performance issues
