• Risk level
• Responsible staff
• Approvals
• Backup
• Rollback plan
• Sandbox testing

Memory Trick

Use P-S-R-B-R:

• Purpose
• Scope
• Risk
• Backup
• Rollback

Shortcut:

• A change without rollback is a bet, not a plan.

Exam Clues

• Maintenance windows reduce user impact.
• Change freezes block noncritical changes during sensitive periods.
• Emergency changes may be faster but still need documentation afterward.
• Peer review helps catch mistakes before implementation.
