The IT Infrastructure Library® for IT Service Management (ITSM)

What is ITIL?

ITIL® is the most widely adopted ITSM (IT service management) framework in the world.

The newest iteration of ITIL – ITIL 4 – was launched in January 2019, with the release of a new edition of the ITIL Foundation manual and the ITIL 4 Foundation certification level

ITIL 4 vs ITIL v3 (2011)

ITIL 4 builds on previous versions of the framework by introducing a new end-to-end digital operating model, which has been designed to help IT teams create, deliver and operate technical products and services that fit their organization’s wider business strategy.

This model is called the ‘service value system’, or ‘SVS’.

The ITIL 4 service value system

The SVS has five core components:

  1. The ITIL service value chain
  2. The 7 ITIL guiding principles
  3. The 34 ITIL practices
  4. Governance
  5. Continual improvement

1. The ITIL service value chain

At the heart of the SVS lies the service value chain, which comprises six activities:

  1. Plan
  2. Improve
  3. Engage
  4. Design and transition
  5. Obtain/build
  6. Deliver and support

These activities can be combined in many different sequences, which ITIL 4 calls ‘value streams’.

One such value stream is the ITIL v3 service lifecycle:

  • Service strategy involves understanding customers and how to develop and successfully execute IT services to meet their needs.
  • Service design ensures that the service is designed efficiently and cost-effectively.
  • Service transition sees the design built and tested.
  • Service operation delivers and manages the service.
  • Continual service improvement provides a mechanism for improving the service, and the technology and processes used in its management.

2. The 7 ITIL guiding principles

The SVS is supported by seven guiding principles, which have evolved from ITIL v3’s nine guiding principles for practitioners and reflect those found in Agile, DevOps and Lean methodologies:

  1. Focus on value
  2. Start where you are
  3. Progress iteratively with feedback
  4. Collaborate and promote visibility
  5. Think and work holistically
  6. Keep it simple and practical
  7. Optimize and automate

They aim to support decisions and actions, and ensure stakeholders’ needs are met efficiently.

3. The 34 ITIL practices

ITIL 4 uses 34 management practices, which follow a more holistic approach than the 26 ITIL v3 processes and are split into three areas: general management practices, service management practices, and technical management practices.

General management practices

  • Architecture management
  • Continual improvement
  • Information security management
  • Knowledge management
  • Measurement and reporting
  • Organizational change management
  • Portfolio management
  • Project management
  • Relationship management
  • Risk management
  • Service financial management
  • Strategy management
  • Supplier management
  • Workforce and talent management

Technical management practices

  • Deployment management
  • Infrastructure and platform management
  • Software development and management

Service management practices

  • Availability management
  • Business analysis
  • Capacity and performance management
  • Change control
  • 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

4. Governance

The SVS incorporates the concept of governance so that organizations can maintain a holistic approach to service value chains, encouraging organizational agility, and ensuring management activities are aligned with corporate objectives.

5. Continual improvement

Like ITIL v3’s continual service improvement model, the ITIL 4 continual improvement model can be applied to all improvement initiatives, enabling momentum to be maintained. Its six steps are:

  1. Business vision, mission, goals, and objectives
  2. Perform baseline assessments
  3. Define measurable tags
  4. Define the improvement plan
  5. Execute improvement actions
  6. Evaluate metrics and KPIs

Four dimensions

ITIL 4 also incorporates four dimensions, similar to ITIL v3’s four Ps (people, products, partners and processes):

  1. Organisation and people
  2. Information and technology
  3. Partners and suppliers
  4. Value streams and processes

ITIL 4 certification scheme

There are changes to ITIL’s professional certification scheme, too. Whereas previous versions of ITIL had five certification levels (Foundation, Practitioner, Intermediate (Service Lifecycle and Service Capability), Expert and Master), ITIL 4 has four:

  • Foundation
  • MP (Managing Professional)
  • SL (Strategic Leader)
  • Master

ITIL 4 Foundation was launched in February 2019. MP, SL and Master will be released later in 2019.

ITIL, ITSM and ISO 20000

Although they have much in common, ITIL and ISO/IEC 20000 serve different purposes.

ISO 20000 is the standard for service management processes. Organisations can attain independently audited certification to the Standard to demonstrate that they are following ITSM best practice.

ITIL provides advice on ITSM best practice. It includes options that may be adopted and adapted by organisations according to business needs, local circumstances and the maturity of the service provider.
