Controlling what is altered.
WHY IT MATTERS
Most incidents follow a change.
WHAT A CHANGE PROCESS REQUIRES
A description of what will change An assessment of risk and impact A plan, with steps A way to reverse it Approval, proportionate to risk Notification of those affected A record of what was done
WHAT TO CLASSIFY
Changes by risk, so routine work is not obstructed.
WHAT STANDARD CHANGES ARE
Low-risk, repeated, pre-approved work following a documented procedure.
WHAT EMERGENCY CHANGES ARE
Changes required immediately, with approval afterwards.
WHAT TO REQUIRE EVEN THEN
A record, and a review.
WHAT TO SCHEDULE
Risky work in defined windows.
WHAT TO FREEZE
Changes during critical business periods.
WHAT TO RECORD ALWAYS
What changed, when, by whom.
WHY
It answers the first question in every incident.
WHAT TO REVIEW
Changes that caused incidents, and why the risk was not identified.
