ITIL is a framework of best practice for IT service management (ITSM): how organisations plan, build, deliver, support and improve technology-enabled services. It is owned by PeopleCert. ITIL is voluntary and organisations cannot be certified to it, but ITIL certifications for individuals are among the most common in IT. ITIL Version 5 was released in early 2026, building on ITIL 4 rather than replacing it.
What is ITIL?
ITIL describes how to manage services, not which tools to use. Its core ideas, kept in ITIL 5, are:
| Element | What it is |
|---|---|
| Service value system (SVS) | How all parts of the organisation work together to create value: guiding principles, governance, the service value chain, practices and continual improvement |
| Service value chain | Six activities: plan; improve; engage; design and transition; obtain/build; deliver and support |
| Four dimensions | Organisations and people; information and technology; partners and suppliers; value streams and processes |
| 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; optimise and automate |
| Practices | 34 sets of organisational resources for doing work, grouped as general management, service management and technical management practices |
What ITIL 5 adds: a single digital product and service lifecycle, more experience-driven guidance with a stronger focus on customer and employee experience, AI guidance across modules, clearer roles and outcomes, and a simpler, role-based certification scheme.
History and why it was introduced
| Year | Milestone |
|---|---|
| 1989 | UK government’s Central Computer and Telecommunications Agency (CCTA) publishes the first ITIL books |
| 2000 to 2002 | ITIL v2 consolidates around service support and service delivery |
| 2007 | ITIL v3 introduces the service lifecycle |
| 2011 | ITIL 2011 edition updates v3 |
| 2013 | AXELOS, a joint venture of the UK government and Capita, takes ownership |
| 2019 | ITIL 4 introduces the service value system and 34 practices, aligned with Agile and DevOps |
| 2021 | PeopleCert acquires AXELOS |
| 2026 | ITIL Version 5 released, with courses rolling out during the year |
ITIL was created because government IT services were inconsistent and costly, and there was no shared description of good IT service management. It spread to the private sector because the same problems existed everywhere.
Main objectives:
- Deliver IT services that create value for customers.
- Make service management consistent and predictable.
- Balance stability with speed of change.
- Improve continuously based on feedback and measurement.
Who uses ITIL?
| Who | Why |
|---|---|
| IT service providers, MSPs and outsourcers | Clients expect ITIL-aligned incident, change and SLA management |
| SaaS companies | To run support, incident response and change management at scale |
| Internal IT departments | To manage service desks, assets and changes |
| Government and public sector | Common requirement in IT service tenders |
| Banks and regulated industries | Supports operational resilience and audit expectations |
Is ITIL mandatory?
No. ITIL is voluntary. It becomes required in practice when tenders ask for ITIL-certified staff or ITIL-aligned processes, or when customers set service management requirements in contracts. Organisations that want a certificate for their service management system use ISO/IEC 20000-1, which is closely aligned with ITIL.
Key requirements: the 34 practices
| Group | Practices |
|---|---|
| General management (14) | Architecture management; continual improvement; information security management; knowledge management; measurement and reporting; organisational change management; portfolio management; project management; relationship management; risk management; service financial management; strategy management; supplier management; workforce and talent management |
| Service management (17) | Availability management; business analysis; capacity and performance management; change enablement; incident management; IT asset management; monitoring and event management; problem management; release management; service catalogue management; service configuration management; service continuity management; service design; service desk; service level management; service request management; service validation and testing |
| Technical management (3) | Deployment management; infrastructure and platform management; software development and management |
The practices most IT companies start with:
- Incident management: restore normal service quickly when something breaks.
- Service desk: a single point of contact for users.
- Change enablement: assess and authorise changes to reduce risk while keeping changes flowing.
- Problem management: find and fix root causes of incidents.
- Service level management: agree, measure and report on service targets.
- Service request management: handle routine requests efficiently.
How to adopt ITIL
- Start where you are. Map how incidents, requests and changes are handled today.
- Agree outcomes with customers: service levels, response times, communication.
- Pick a few practices to formalise first, usually incident, change, service desk and service level management.
- Define roles and workflows that fit your size. A five-person SaaS team doesn’t need a change advisory board; peer review and automated testing can meet change enablement goals.
- Choose an ITSM tool that supports the workflows and reporting you need.
- Train key staff, typically starting with ITIL Foundation.
- Measure and improve: incident volumes, time to restore, change success rate, customer satisfaction.
- Expand to problem, knowledge, asset and continuity management as you grow.
Documentation and policies
ITIL doesn’t prescribe documents. Common outputs are:
- Service catalogue
- Service level agreements and operational level agreements
- Incident, request, change and problem management procedures
- Major incident process and communication templates
- Change policy, including standard (pre-approved) changes
- Configuration and asset records
- Knowledge base
- Service continuity plans
- Supplier contracts and reviews
- Service reports and improvement registers
Certification and assessments
- Individuals take ITIL certifications from PeopleCert, starting with Foundation. Under ITIL 5, ITIL 4 Foundation still counts as a prerequisite for advanced modules, and transition courses are available for higher-level ITIL 4 holders.
- Organisations cannot be ITIL certified. They can certify a service management system to ISO/IEC 20000-1 or have ITIL maturity assessed by consultants.
Cost
| Cost area | What drives it |
|---|---|
| Publications and membership | ITIL guidance is sold by PeopleCert, with membership options |
| Training and exams | Number of staff and certification levels |
| ITSM tools | Licences scale with agents and features |
| Process design | Internal time or consultants |
Benefits
- Faster, more consistent incident resolution.
- Fewer failed changes and outages.
- Clear service levels and reporting for customers.
- A shared vocabulary with enterprise clients and their IT teams.
- A foundation for ISO 20000-1 certification.
Risks of poor service management
- Repeated outages and slow recovery.
- SLA breaches and service credits.
- Lost customers and failed tenders.
- Audit findings on change and incident controls.
Common mistakes
- Copying heavy processes designed for large enterprises.
- Treating change management as a gate that slows releases, instead of enabling safe change.
- Measuring tickets instead of outcomes.
- Tool first, process later.
- Ignoring problem management, so the same incidents recur.
Challenges for IT companies
- Fitting ITIL to DevOps and continuous delivery.
- 24/7 incident response with small teams.
- Multi-tenant SaaS incidents that affect many customers at once.
- Integrating with customers’ own ITSM processes.
Best practices
- Use automated testing, peer review and deployment pipelines as change controls.
- Keep a major incident playbook with communication templates and status page updates.
- Run blameless post-incident reviews and feed them into problem management.
- Publish a simple service catalogue and SLAs.
- Pair ITIL with COBIT for governance and ISO 27001 for security.
Tools that help
| Category | Supports |
|---|---|
| ITSM platform | Service desk, incidents, requests, changes, problems |
| Monitoring and observability | Monitoring and event management |
| On-call and incident response tools | Major incident handling |
| Status page | Customer communication |
| CMDB or asset management | Configuration and asset management |
| Knowledge base | Knowledge management |
How ITIL relates to other frameworks
| Framework | Relationship |
|---|---|
| ISO/IEC 20000-1 | Certifiable service management standard closely aligned with ITIL |
| COBIT | Governance framework; ITIL implements many of its management objectives. See ITIL vs COBIT |
| ISO 27001 | Shares incident, change, asset and supplier management concepts |
| ISO 22301 | Business continuity; complements service continuity management |
| ISO/IEC 38500 | IT governance principles for the board |
Real-world examples
- Public sector tenders. UK and Indian government IT service tenders commonly ask for ITIL-aligned processes or ITIL-certified staff.
- Managed service providers typically describe their service desk, incident and change processes in ITIL terms in contracts and SLAs.
- Illustrative scenario, not a real company: a 60-person SaaS company suffers a long outage with poor customer communication. It introduces an ITIL-style major incident process, a status page, post-incident reviews and problem management, and halves repeat incidents within two quarters.
