ITIL is a framework of practices for managing IT services. Beginners often treat it as exam theory, but its practices describe work that operations teams already do. Incident management restores service quickly. Problem management finds causes. Change enablement controls risk. Service level management tracks promises. Knowing the names helps in interviews, but knowing the work matters more.
Where each practice appears
- Incident management: the ticket queue, priority levels, and escalation paths you use on every shift.
- Problem management: the investigation behind repeat incidents, including known errors and workarounds.
- Change enablement: the approval board and the checks before a release, covered in a companion post here.
- Service request management: the standard requests, such as access or software, handled through the catalog.
When studying ITIL, attach each practice to a task you have done or watched. Framework knowledge without a concrete example rarely survives an interview question.
