IT Service Incident Management
IT service incident management is the coordinated work of recording, prioritizing, investigating, and resolving disruptions to technology services. Its immediate goal is to restore useful service and limit business impact, while separate problem and change practices handle deeper causes and controlled permanent fixes.

Intro
IT Service Incident Management
IT service incident management coordinates the response to an unplanned service interruption or reduction in service quality. Its immediate purpose is service restoration. A responder may restore service with a workaround before anyone knows the underlying cause. That is acceptable because problem management investigates causes, while change management controls lasting modifications.
An incident is viewed through its effect on a service, not only through a failing device or application. A database alert is an event. It becomes an incident when the condition disrupts a service or threatens an agreed service outcome. A user report can also reveal an incident before monitoring does. Both paths should create or update one authoritative incident record.
The operating model
The practice connects four working areas:
- Intake and detection receive reports from users, monitoring, support staff, and suppliers.
- Control records the incident, categorizes it, assesses impact and urgency, assigns priority, and maintains ownership.
- Restoration diagnoses the disruption, applies a workaround or repair, verifies recovery, and escalates when the current team lacks authority, skill, or time.
- Communication and learning keep affected people informed, preserve the timeline, close the record with evidence, and route follow-up into problem, knowledge, or change work.
