Change Management
Practice · Beginner
The practice of proposing, approving, scheduling, and reviewing changes so production is not altered on impulse. A rollback plan is part of a serious change.
It slows down a reckless edit on purpose. The record says what will change, why, when, and how to undo it if the result is bad.
Example: A firewall change is approved for Tuesday night, with the previous rules saved so they can be restored.
Common misconception
- The practice is not bureaucracy for its own sake. It exists so an outage has an owner and a way back.
