Difference between expedited, emergency, retrospective changes

Question

Accepted Answer

Expedited, emergency, and retrospective changes differ in their urgency and timing.

Expedited changes are urgent but planned changes that require faster implementation than normal changes.
Emergency changes are unplanned and require immediate implementation to prevent or resolve a critical situation.
Retrospective changes are made after an incident or problem has occurred to prevent it from happening again in the future.
Expedited and emergency changes are made before the change is implemented, while retrospective changes are made after the change has been implemented.
Examples of expedited changes include security patches and critical bug fixes, while examples of emergency changes include system failures and security breaches.
Examples of retrospective changes include implementing new processes or procedures to prevent future incidents.
