ITIL 4 — Information Technology Infrastructure Library

Why does it matter?

ITIL 4 gives IT and business teams one vocabulary for how services create value, which is why it is the most widely cited reference for IT service management. Its status is changing: PeopleCert has introduced ITIL (Version 5) and plans to retire the ITIL 4 certification modules at the end of 2027.

Key benefits include:

• A shared language for value

The SVS and its guiding principles describe how demand and opportunity become value, so IT, product and business teams discuss services in the same terms.

• Practice-level guidance

34 management practices, including incident management, change enablement, problem management and service desk, give teams a named scope for each capability.

• Flexible adoption

Organizations choose the practices and guidance that fit them, and the framework presents them as principles to adapt, not rules to apply.

• A recognized qualification path

ITIL 4 Foundation leads to the Managing Professional, Strategic Leader and Practice Manager designations and, at the top, ITIL Master.

• A clear transition route

ITIL 4 Foundation counts as a prerequisite for ITIL (Version 5), and PeopleCert offers an ITIL Foundation Bridge (Version 5) module for ITIL 4 holders.

How does it work?

Start with the service value system. Demand and opportunity enter the SVS, and the service value chain turns them into value through six activities (plan, improve, engage, design and transition, obtain/build, deliver and support). Governance directs and controls the whole system, and continual improvement runs through every part of it.

Apply the guiding principles to decisions: focus on value, start where you are, progress iteratively with feedback, collaborate and promote visibility, think and work holistically, keep it simple and practical, and optimize and automate.

Select the practices that support each value chain activity. ITIL 4 groups its 34 practices as 14 general management, 17 service management and 3 technical management practices, and each has an official practice guide. Teams then consider all four dimensions for every practice so that people, technology, partners and processes are covered together.

Key Elements

• Service value system

Guiding principles, governance, service value chain, practices and continual improvement work together to co-create value with consumers.

• Four dimensions

Organizations and people; information and technology; partners and suppliers; value streams and processes.

• Seven guiding principles

Focus on value; start where you are; progress iteratively with feedback; collaborate and promote visibility; think and work holistically; keep it simple and practical; optimize and automate.

• Service value chain

Six activities: plan, improve, engage, design and transition, obtain/build, deliver and support.

• 34 management practices

14 general management, 17 service management (such as incident management, change enablement and service desk) and 3 technical management practices.

• Certification scheme

ITIL 4 Foundation, then Managing Professional, Strategic Leader and Practice Manager designations, with ITIL Master above them; designations share a renewal date three years after the latest exam.

What does it cover?

ITIL 4 applies to the management of IT-enabled services in any organization, from internal IT departments to managed service providers. It covers service management from strategy to operations, including service request, incident, problem and change handling, and its structures can be used outside IT (the Version 5 material notes adaptation for enterprise service management). It does not contain regulatory requirements. Adoption is voluntary, and a certificate attests an individual's knowledge, not an organization's compliance.

What are its objectives?

ITIL 4 sets out to help organizations create value through services in a way that adapts to their own context.

Provide a common model, the SVS, for how services create value for consumers and the provider.

Offer guiding principles that inform decisions in every situation, whatever the organization's size or structure.

Describe 34 practices that teams can adopt, adapt and combine through the four dimensions.

Build continual improvement into every activity through the continual improvement model.

Support careers and organizational capability through the ITIL 4 qualification scheme.

Framework in Context

ITIL 4 is a source of practices that other standards and frameworks reference. ISO/IEC 20000-1 is the certifiable management-system standard for service management, which organizations can implement using ITIL practices; COBIT 2019 sets governance objectives that ITIL practices help achieve; FitSM, IT4IT, SIAM and ISO/IEC 27001 cover related ground. ITIL itself does not certify organizations. The same publisher has moved on to ITIL (Version 5), which keeps the value system and guiding principles of ITIL 4 and adds product, experience, transformation and AI governance modules.
