Frameworks and standards

ITIL: the world’s most widely used guidance for IT service management

ITIL helps organisations design, deliver, support and improve the digital products and services their customers and users rely on. Here is what it is, where it came from, how certification works and why organisations adopt it.

In brief

What is ITIL?

ITIL is a collection of good practice for managing IT and digital services. It describes how successful organisations plan, build, run, support and improve their services, so you do not have to work it all out from scratch.

The name originally stood for Information Technology Infrastructure Library, although today it is simply known as ITIL. It is a framework, not a standard: there is no rulebook to comply with, and organisations are encouraged to adopt and adapt the parts that help them most.

ITIL covers everyday activities, such as handling incidents and service requests, through to strategy, governance, customer experience and continual improvement. The latest version, ITIL (Version 5), launched in early 2026. It extends ITIL 4 from IT service management towards managing digital products and services as a whole, with stronger guidance on experience, sustainability and the responsible use of AI.

ITIL 4, published in 2019, is still widely used, and much of it carries forward into Version 5, including the guiding principles and the 34 management practices.

Core ideas

The key ideas in ITIL

Value is co-createdServices exist to help customers achieve outcomes they care about. ITIL keeps the focus on value, outcomes, costs and risks, not on activity for its own sake.

Guiding principlesSeven principles, such as focus on value, start where you are, and keep it simple and practical, guide decisions in any situation.

Four dimensionsEvery service depends on organisations and people, information and technology, partners and suppliers, and value streams and processes. Ignore one and the service suffers.

Product and service lifecycleVersion 5 introduces an eight-stage lifecycle: discover, design, acquire, build, transition, operate, deliver and support.

Management practicesThirty-four practices, such as incident management, change enablement and service level management, provide practical guidance for specific areas of work.

Continual improvementImprovement is built into everything, using a simple model: where are we now, where do we want to be, how do we get there, and did we get there?

Ownership and history

Who owns ITIL, and where did it come from?

ITIL began in the late 1980s, when the UK government’s Central Computer and Telecommunications Agency (CCTA) set out to document good practice for managing government IT. It quickly spread to the private sector and around the world.

Ownership later passed to AXELOS, a joint venture between the UK Cabinet Office and Capita. In 2021, PeopleCert acquired AXELOS, and it now owns ITIL and runs its certification scheme, alongside other frameworks such as PRINCE2.

Major versions include ITIL v2 (around 2000), ITIL v3 (2007, updated in 2011), ITIL 4 (2019) and ITIL (Version 5) in 2026. Each version has broadened the scope, from IT operations to end-to-end service management, and now to digital product and service management.

Certifications

ITIL certifications for individuals

ITIL certification is for people, not organisations. The scheme is managed by PeopleCert and delivered through accredited training organisations and online exams. Under ITIL (Version 5), everyone starts with Foundation and can then follow one or more streams of advanced modules. ITIL 4 Foundation is still recognised as a prerequisite for the Version 5 advanced modules.

Entry levelITIL FoundationCovers the key concepts, principles and terminology. Version 5 Foundation is a 60-minute, closed-book, multiple-choice exam of 40 questions, and training is recommended but not mandatory.

DesignationITIL Managing ProfessionalFor people who run and deliver services. Requires Foundation plus the Product, Service, Experience and Transformation modules.

DesignationITIL Strategic LeaderFor leaders who shape digital strategy and governance. Requires Foundation plus the Strategy and Transformation modules.

DesignationITIL Practice ManagerFor people who own or manage specific practices, such as incident, change or service level management, through practice-focused modules.

ExtensionITIL AI GovernanceA standalone module on the responsible, ethical and compliant adoption of AI within digital product and service management.

Highest levelITIL MasterRecognises the proven ability to apply ITIL in complex, real-world situations, assessed on how the candidate has applied ITIL in their own work rather than through a standard exam.

ITIL 4 and Version 5 certifications are valid for three years and can be kept current through PeopleCert’s renewal options, such as continuing professional development or retaking an exam. Exact module names, prices and exam formats are published by PeopleCert and can change, so please check before booking.

Benefits

Why organisations adopt ITIL

A common languageIT teams, suppliers and the business use the same terms, which reduces misunderstanding and speeds up collaboration.

Better user experienceClear ways to get help, realistic service levels and faster resolution mean happier, more productive users.

Less firefightingProblem management and knowledge sharing tackle root causes, so the same issues stop coming back.

Lower riskProportionate change enablement and good information about your services reduce outages caused by change.

Value for moneyUnderstanding services, demand and costs helps leaders prioritise investment where it matters most.

Easier recruitment and onboardingITIL is widely recognised, so new staff and suppliers arrive already familiar with the concepts.

Who it is for

Who should use ITIL?

Any organisation that provides IT or digital services, to internal colleagues or to external customers, can benefit. That includes in-house IT departments, managed service providers, software and SaaS companies, and public sector bodies.

Size does not matter as much as people think. A small IT team might adopt a handful of practices, such as incident, request and change, in a lightweight way. A large enterprise might use the full breadth of ITIL across many teams and suppliers. The guiding principle “start where you are” applies to everyone.

ITIL is also increasingly used outside IT, by HR, facilities and other shared service teams that want the same clarity in how they deliver services.

Roles that benefit most

Service desk analysts and team leaders
Support engineers and technical teams
IT service managers and process owners
Product and service owners
Heads of IT, CIOs and digital leaders
Consultants, auditors and suppliers working with IT

How it fits

How ITIL works with other frameworks

ITIL is designed to work alongside other approaches rather than replace them.

ISO/IEC 20000: ITIL tells you how to do service management well; ISO/IEC 20000 sets the requirements you can be certified against. Many organisations use ITIL to meet the standard.
COBIT: COBIT governs and directs IT as a whole; ITIL provides detailed guidance on managing the services within it.
DevOps and Agile: ITIL 4 and Version 5 explicitly support fast, iterative delivery, with practices such as change enablement adapted to automated pipelines.
ISO/IEC 27001: ITIL practices such as incident, change and asset management provide much of the operational evidence an information security management system needs.
PRINCE2: improvement initiatives are often run as projects, and PRINCE2 gives them structure and control.
