ITSM (IT service management) is the framework that treats IT operations as a delivery business: services, customers, SLAs, incidents, problems, changes. It is process-heavy by intent — the discipline is what produces reliable IT at scale. ITIL is the most common ITSM framework, but the practice exists with or without the label.
IT Glossary
What is ITSM?
IT service management — the disciplined practice of delivering IT as a service to a business.
What the practice is actually for.
- Without ITSM discipline, the same incident happens repeatedly and nobody captures the fix
- Change management is what keeps Friday-afternoon deploys from being Saturday-morning emergencies
- Service catalogs let users self-serve common requests without filing tickets
The practical version.
Tickets with lifecycle states, change-management workflows, audit trails, and a self-service portal. Smart routing, automation, and AI assist mean ITSM discipline does not require a 20-person process team.
