Helpdesk Concepts

Service Desk

Definition

A service desk is the single point of contact between an IT organization and its users, managing not just support requests but also incidents, service requests, changes, and other IT service management (ITSM) processes.

Also known as: IT service deskITSM desk

How it works

Rooted in ITSM frameworks like ITIL, a service desk handles the full lifecycle of IT services. Beyond answering questions, it manages incidents (something's broken), service requests ("I need access"), problems, and changes — often with an integrated service catalog and asset tracking.

It's typically internal (serving employees), whereas a help desk is more often customer-facing and focused on resolving individual issues.

Why it matters

The service desk is the operational hub for IT support. By coordinating incidents, requests, and changes through one system with defined processes, it keeps IT services reliable and gives the business a single, accountable place to go when something's needed or broken.

Frequently asked

What is the difference between a service desk and a help desk?

A help desk resolves individual support requests, often for external customers. A service desk is broader and ITSM-oriented — it also manages incidents, service requests, changes, and assets, usually for internal users.

Is a service desk only for IT?

It originated in IT and is defined by ITSM frameworks, but the model has expanded — HR, facilities, and other internal teams increasingly run service desks using the same request-and-fulfillment approach.
