What is ITIL?

Last updated 1 September 2026 · 6 min read

Every organisation that runs IT — a bank, a telco, a hospital, a government department — has to answer the same questions. How do we handle incidents fast? How do we roll out changes without breaking things? How do we know IT is actually helping the business? ITIL is the shared playbook that answers them.

So what does ITIL actually do?

ITIL gives IT teams a common language and a set of proven practices for designing, delivering and improving services. Rather than every team inventing its own way of doing things, ITIL describes what “good” looks like — for incident management, change enablement, service requests, problem management and more — and lets you adapt it to your organisation.

ITIL 5 organises this around the Service Value System: the guiding principles, the service value chain, the four dimensions, and the practices that turn demand into value. You don’t need to memorise all of it to start — that’s what Foundation is for.

ITIL 4 vs ITIL 5 — what changed?

ITIL 4 introduced the value-focused model most people know. ITIL 5, released in February 2026, builds on it — refreshing the guidance and reflecting how modern teams work, including where AI and other frameworks fit in. ITIL 4 certificates remain valid and bridge into version 5, so you’re not starting over. If you’re certifying now, start with the current ITIL® Foundation (Version 5) course.

What’s the ITIL certification path?

Foundation is the front door — it proves you understand the framework and the vocabulary. From there you can progress into the higher, more specialised modules later in your career.

For almost everyone, Foundation is the right — and often the only — certification you need to add ITIL to your CV.
