Emergency Change

Emergency change is a controlled exception, not a permission slip for skipping thought. The trigger may be active exploitation, an outage, imminent data loss, or a defect that makes normal scheduling unsafe. In that moment, the incident commander or service owner needs authority to act, the implementer needs a constrained plan, and the approver needs enough information to accept the immediate risk. Documentation will often be shorter before execution, but it cannot be absent: affected scope, action, rationale, approver, and recovery direction should be captured while the facts are fresh. The worst pattern is relabeling ordinary late work as urgent because planning failed upstream.

These articles examine the break-glass path from expedited approval through post-implementation review. They address emergency CAB participation, short deadline vulnerability fixes, the complications of incomplete patches, and the retrospective evidence needed once service is stable. The key tension is speed versus control, but it is not a choice between them. A disciplined team predefines who can authorize emergency work, what minimum checks survive the time pressure, how stakeholders are notified, and when the record returns for review. That follow-up is where recurring emergency categories become visible. If the same class of change repeatedly needs a bypass, the remedy is usually better standardization, capacity, or ownership - not a more permissive exception code.
