For the first time since 2019, ITIL Foundation has a new edition. The latest version of the framework was released on 12 February 2026, and while it officially carries just the name “ITIL,” the industry has settled on calling it ITIL Version 5 (or ITIL 5) to tell it apart from ITIL 4. If you hold an ITIL 4 Foundation certificate, are studying for it now, or are deciding which one to sit, here’s a clear-eyed look at how the two Foundation levels differ.
The short version: this is evolution, not revolution. ITIL 5 keeps the conceptual backbone of ITIL 4 and refines the parts that practitioners found confusing or overwhelming. But there are several genuinely new ideas at Foundation level that are worth understanding.
A change of name and scope
ITIL has not officially stood for “IT Infrastructure Library” for years, but Version 5 makes the break explicit. ITIL is now described as a framework and best-practice guidance for digital product and service management — a deliberate widening of scope. Where ITIL 4 was framed primarily around services, Version 5 treats products and services as two sides of the same technology-enabled solution, and it tries to bring product and service communities together under one shared language.
You’ll see this reflected in renamed components. The Service Value System (SVS) from ITIL 4 becomes the ITIL Value System in Version 5. It’s the same organizing idea — how the pieces of the framework combine to create value — but relabeled to fit the broader product-and-service framing.
The biggest structural addition: the Product and Service Lifecycle Model
If there’s one headline change at Foundation level, it’s the new eight-stage ITIL Product and Service Lifecycle Model. It lays out eight key activities that apply to every product and service:
- Discover
- Design
- Acquire
- Build
- Transition
- Operate
- Deliver
- Support
ITIL 4 had nothing quite like this. Its equivalent structure was the six-activity Service Value Chain (Plan, Improve, Engage, Design & Transition, Obtain/Build, Deliver & Support). That value chain still exists in Version 5, but it has been simplified and made more recognizable, and the new lifecycle model sits alongside it to show more explicitly how work flows from an idea through to ongoing support.
AI-native and complexity-native
Two guiding principles shape the entire Version 5 Foundation, and both are new in emphasis:
- AI-native. ITIL 5 was written with the use of AI — and the need for effective AI governance — built in from the start, rather than bolted on. This reflects how organizations actually operate now. (There’s even a dedicated AI-governance extension module in the wider Version 5 scheme.)
- Complexity-native. Version 5 assumes a VUCA (volatile, uncertain, complex, ambiguous) world. Rather than treating management as simply executing a plan, it explicitly supports experimentation to find the right direction, and it gives guidance on how to do that.
ITIL 4 acknowledged uncertainty and modern ways of working, but it didn’t foreground AI or experimentation the way Version 5 does.
Practices: fewer surprises at Foundation
A common complaint about ITIL 4 Foundation was that its 34 practices felt overwhelming for people new to the framework. Version 5 responds by introducing key terminology and clear definitions for several management practices — such as incident, problem, and change management — directly at Foundation level, with the full detail living in the separate ITIL Practice Guides. The aim is to make the entry point more practical for beginners and more useful for established practitioners, without dumping the entire catalogue on day-one learners.
Concepts pulled down from advanced modules
Some material that used to live in higher-level ITIL 4 modules now appears at Foundation. The clearest example is the service journey model, which in ITIL 4 was part of the Drive Stakeholder Value module and now gets introduced at Foundation in Version 5 (deeper application still lives in advanced modules, especially ITIL Experience). The continual improvement model also returns in a refined form, so learners meet a concept early that carries through every advanced module.
How it’s taught
Version 5 leans much harder into practicality and storytelling. A fictional narrative — a company going through an AI-enabled transformation — runs through the Foundation guidance, and the same scenario and characters reappear in advanced modules and in scenario-based exam questions. The Foundation guidance also includes appendices designed as a practical toolkit. The whole design answers the question ITIL 4 learners kept asking: not just what the concepts are, but how to apply them.
Certification paths and the bridge
The certification scheme keeps a familiar shape. ITIL Foundation remains the entry point, and the advanced designations echo ITIL 4’s names: Practice Manager, Managing Professional, Strategic Leader, and Master. New core publications sit above Foundation — ITIL Strategy, ITIL Product, ITIL Service, and ITIL Experience — plus an ITIL Transformation module that runs across every pathway.
Crucially for anyone already certified:
- You do not need to redo Foundation from scratch. An existing ITIL 4 Foundation certificate remains valid and acts as a prerequisite for advanced Version 5 modules.
- A short ITIL Foundation Bridge (Version 5) — a one-day course and short exam released 26 February 2026 — lets ITIL 4 holders catch up on just the new and changed concepts without repeating unchanged material.
- ITIL 4 is not being switched off overnight; it remains available during a phased rollout of Version 5.
What stayed the same
It’s worth stressing how much carries over. The guiding principles, the value system (governance, value chain, practices, continual improvement), the focus on value co-creation, defined roles and responsibilities, and continual improvement are all still central. If you know ITIL 4, you already understand most of the scaffolding of Version 5.
Which should you take?
- New to ITIL and certifying in 2026 or later? Go straight for ITIL Foundation (Version 5) — it’s the current edition and reflects how organizations work today, including AI.
- Already hold ITIL 4 Foundation? Your certificate still counts. The one-day Foundation Bridge is the efficient way to get current, and you can proceed into advanced Version 5 modules without re-sitting Foundation.
- Mid-study for ITIL 4 right now? Finishing is not wasted effort — ITIL 4 remains valid and bridges cleanly into Version 5.
The bottom line
ITIL 4 introduced the big philosophical shift — from rigid processes to a holistic, value-oriented service value system. ITIL (Version 5) doesn’t overturn that; it sharpens it. The redefinition around digital product and service management, the eight-stage lifecycle model, the AI-native and complexity-native framing, clearer practice definitions at Foundation, and a scenario-driven teaching style all point the same direction: making the framework more practical and more obviously applicable to the way technology work happens now.
