ITIL® Methodology

Welcome to our in-depth exploration of the ITIL methodology, a cornerstone of modern IT service management. Originating in the late 1980s, ITIL has evolved from its initial version, focusing on basic IT management practices, to the sophisticated and adaptable ITIL 4 framework we see today. This evolution mirrors the rapidly changing IT landscape, with each iteration, from ITIL V1 to ITIL 4, enhancing its approach to align with emerging technologies and business needs.

ITIL 4, particularly stands out with its integration of Agile, DevOps, and Lean methodologies, emphasising a holistic and flexible approach to service management.

In this blog, we delve into the key elements of ITIL 4, including the Service Value System, guiding principles, and its emphasis on continual improvement, collaboration, and value creation in the realm of IT services.

Join us as we unpack the nuances and benefits of ITIL 4, a framework that has become pivotal in shaping effective IT service management strategies.

Is ITIL a methodology?

ITIL is not technically a methodology, but rather a set of best practices and guidelines for ITSM. Unlike a strict methodology which provides a step-by-step process for achieving a specific goal, ITIL is more flexible. It offers a framework of best practices that organisations can adapt and apply according to their specific requirements and the nature of their IT environment. ITIL focuses on aligning IT services with the needs of the business, improving service delivery, and ensuring high levels of customer satisfaction.

What is ITIL?

ITIL 4 is the latest evolution of the ITIL framework, which represents a significant update from the previous version, ITIL V3. ITIL 4 was released in 2019 and introduces several new concepts and practices that reflect the modern digital environment.

ITIL 4 is beneficial for organisations looking to manage IT services in an effective and efficient way, particularly in the context of the fast-paced and complex digital environment. It supports organisations in navigating the Fourth Industrial Revolution, with an emphasis on digital transformation and the management of digital services.

What Does ITIL Stand For?

ITIL stands for Information Technology Infrastructure Library, is it now on its fourth iteration. ITIL 4 does not follow the previous naming schemes of ITIL, ITIL V2, and ITIL V3. This is because PeopleCert wanted to align ITIL with the fourth industrial revolution, so we now have ITIL 4.

What are The Elements of ITIL?

ITIL 4 introduces several key elements that collectively provide a comprehensive and flexible framework for IT service management. These elements are designed to be adaptable to the diverse and dynamic nature of modern IT environments. The key elements of ITIL 4 include:

  • Service Value System (SVS)
  • Service Value Chain (SVC)
  • Four Dimensions of Service Management
  • Guiding Principles
  • Practices
  • Value streams
  • Continual Improvement Model

The ITIL methodology comprises of multiple elements, that we will cover below:

Service Value System (SVS)

The SVS represents a holistic approach to service management. It integrates various components of the ITIL framework into a cohesive system that focuses on the co-creation of value. This system is dynamic and allows for a high degree of adaptability, making it suitable for a wide range of organisations and service management challenges. The SVS provides a holistic approach to the creation, delivery, and continual improvement of services. It emphasises the importance of creating value through services.

The Four Dimensions Model

This model ensures a holistic approach to service management. These four dimensions are considered critical elements that need to be balanced and integrated to facilitate value effectively and efficiently for customers and other stakeholders through IT-enabled services. It includes considerations of:

  • Organisations and People: This dimension emphasises the importance of having the right organisational structure, culture, staffing, and competencies. An organisation must ensure it has the right people with the right skills and knowledge, and that they are organised in a way that supports its objectives. This includes leadership, workforce planning, and employee engagement and satisfaction, which are crucial for effective service management.
  • Information and Technology: This dimension covers the information and technology aspects of service management. It includes not only the technology required to deliver services but also the information that is used and managed in the service lifecycle. The focus is on aligning IT with the business, ensuring the right technology is in place, and managing information effectively.
  • Partners and Suppliers: Organisations typically work in a network of partners and suppliers, and this dimension acknowledges the importance of these relationships. It involves ensuring that partners and suppliers are integrated into service delivery and that their contributions and risks are managed effectively. This dimension includes relationship management, contract management, and ensuring that partners and suppliers align with the organisation’s culture and objectives.
  • Value Streams and Processes: This dimension involves the workflows, processes, and procedures necessary to deliver services. It focuses on designing, managing, and improving these processes to ensure they are efficient, effective, and capable of delivering value. It includes process design, optimisation, and continual improvement.

Guiding Principles

ITIL 4 includes seven guiding principles that were adapted from ITIL Practitioner. These principles are universal and apply to virtually any initiative or aspect of service management. They include:

  • Focus on Value: Everything an organisation does should link back directly to value for the stakeholders. This principle emphasises understanding and focusing on what is truly valuable to customers and users.
  • Start Where You Are: Before embarking on any change, it's important to understand the current state and not to start from scratch unnecessarily. This involves appreciating existing assets, capabilities, and processes, and identifying opportunities for improvement.
  • Progress Iteratively with Feedback: Rather than attempting large-scale changes in one go, this principle advises working in a more agile manner, making smaller, manageable improvements and using feedback to guide the next steps. This approach reduces risk and allows for more flexibility and adaptability.
  • Collaborate and Promote Visibility: Breaking down silos and encouraging transparency across all levels of the organisation is vital. Collaboration improves decision-making and ensures that everyone understands how their work contributes to value creation.
  • Think and Work Holistically: No service or component stands alone. The principle of working holistically ensures an integrated and coordinated approach to service management, considering how all parts work together.
  • Keep It Simple and Practical: This principle involves simplifying processes and procedures, reducing complexity, and focusing on activities that bring value. It encourages removing unnecessary steps that do not contribute to the creation of value.
  • Optimise and Automate: Prioritise process optimisation before considering automation. Automating inefficient or unnecessary processes only amplifies their flaws. First, streamline and optimise, then, where appropriate, use technology to automate.

Service Value Chain

The Service Value Chain is a core component of the SVS. It's an operating model for the creation, delivery, and ongoing improvement of services. It consists of six activities: plan, improve, engage, design & transition, obtain/build, and deliver & support. Let’s have a detailed look at each of the six key activities in the Service Value Chain:

  • Plan: This activity involves the overall coordination and alignment of the organisation’s resources and capabilities to the strategic objectives. It includes activities like defining policies, ensuring governance, and managing risks. The planning activity ensures that the direction and guidelines are clear for all other activities in the value chain.
  • Improve: This is about ensuring continual improvement of products, services, and practices across all value chain activities and the four dimensions of service management. It involves assessing and analysing the current performance and identifying areas for enhancement.
  • Engage: Engagement focuses on understanding stakeholder needs, expectations, and feedback. It includes establishing a good relationship with customers, users, and other stakeholders. Activities like communication, marketing, gathering feedback, and managing customer relationships fall under this category.
  • Design & Transition: This activity ensures that services are designed effectively to meet stakeholder needs and can be transitioned into the live environment smoothly. It involves designing new or changed services, service components, and processes, and then transitioning them into operation while ensuring that changes are managed effectively.
  • Obtain/Build: This refers to the activities involved in obtaining service components from suppliers and integrating them, or building service components internally. It includes aspects of service configuration, acquisition, and development.
  • Deliver & Support: This is the execution phase where services are delivered and supported as agreed upon with customers. It involves managing the service levels, resolving incidents and service requests, and ensuring the services are delivered effectively and efficiently to fulfil agreed-upon service commitments.

Each of these activities represents a set of interconnected actions, decisions, or processes that an organisation undertakes to deliver value to its customers and users. The Service Value Chain is adaptable and can be configured in various ways to produce different value streams. This flexibility allows organisations to tailor their approach to service management according to the specific demands and opportunities they face, ensuring they can respond effectively to dynamic customer and business needs.


In ITIL 4, "Practices" refer to sets of organisational resources designed for performing work or accomplishing an objective. The introduction of the term "practices" in ITIL 4 marks a shift from the more process-focused approach of previous ITIL versions. Practices include not just processes, but also people, information, tools, and other resources necessary for managing and delivering services. ITIL 4 defines 34 practices, which are grouped into three categories:

  • General Management Practices: These practices are adopted from general business management domains and have been adapted for service management purposes. They are broad and cover areas that are crucial to effective and efficient service management. Examples of general management practices include risk management, project management, workforce and talent management, and continuous improvement.
  • Service Management Practices: These are specific to the activities and capabilities required to provide services. They are more focused on the conceptual aspects of service management. Examples include service level management, service catalogue management, incident management, service request management, and service desk.
  • Technical Management Practices: These practices focus on the technology and technical aspects necessary for delivering services. They are particularly crucial in the design, development, and improvement of services that rely on technology. Examples of technical management practices include deployment management, infrastructure and platform management, software development and management, and IT asset management.

Practices in ITIL 4 are designed to be adaptable and flexible, allowing organisations to apply them in various environments and situations. They also facilitate integration with other methodologies and frameworks like Agile, Lean, and DevOps, ensuring a cohesive and comprehensive approach to service management.

Continual Improvement

Continual improvement is a fundamental concept in ITIL 4, emphasising the ongoing effort to enhance services, processes, and practices in service management. This concept aligns with the recognition that the business environment is dynamic, and organisations must continuously adapt and evolve to meet changing needs and expectations. Here are the key aspects of continual improvement in ITIL 4:

  • Continual Improvement Model: ITIL 4 introduces a structured approach to continual improvement, represented by the Continual Improvement Model. This model provides a clear and systematic way to approach improvement within organisations. It consists of a series of steps: What is the vision? Where are we now? Where do we want to be? How do we get there? Take action. Did we get there? How do we keep the momentum going? This model can be applied to all levels of the organisation, from strategic to operational.
  • Embedding Improvement Culture: Continual improvement in ITIL 4 is not just a process or a set of activities; it's about embedding a culture of improvement throughout the organisation. This involves encouraging a mindset where all employees are actively looking for ways to improve, sharing ideas, and learning from experiences.
  • Iterative Approach: The approach to improvement in ITIL 4 is iterative, meaning it advocates for making small, incremental changes rather than large, disruptive ones. This aligns with agile methodologies and allows for more flexibility and responsiveness to changes in the business environment.
  • Using Metrics and Measurements: Continual improvement relies heavily on metrics and measurements to assess current performance and identify areas for improvement. It involves setting clear goals and objectives, measuring performance against these, and analysing the data to understand what changes need to be made.
  • Alignment with Organisational Objectives: Improvements are not made in isolation but are aligned with the overall strategic goals and objectives of the organisation. This ensures that all improvement efforts contribute towards achieving broader business outcomes.
  • Integration with Other Practices: Continual improvement is integrated with other ITIL practices. For example, problem management might identify areas for improvement, while change management might implement the improvements.
  • Encouraging Feedback and Collaboration: Continual improvement in ITIL 4 emphasises the importance of feedback from stakeholders, including customers, employees, and suppliers. Collaboration across teams and departments is crucial to identify improvement opportunities and implement them effectively.

Integration with Other Practices

The integration of ITIL 4 with other practices and methodologies is a significant aspect of its design, acknowledging the diverse and dynamic nature of modern IT environments. ITIL 4 is not intended to be a standalone or isolated framework; rather, it is designed to be compatible and complementary with other practices that organisations might be using. This integration is essential for creating a more flexible, responsive, and efficient approach to service management. Here are key areas of integration:

  • Agile: Agile methodologies focus on iterative development, customer collaboration, responding to change, and delivering functional products. ITIL 4's flexible and customer-focused approach aligns well with Agile, especially in its emphasis on delivering value quickly and adapting to changing requirements.
  • DevOps: DevOps is a set of practices that combines software development (Dev) and IT operations (Ops) aiming to shorten the systems development life cycle and provide continuous delivery with high software quality. ITIL 4 supports this by providing practices for managing services over their lifecycles and facilitating collaboration and communication across various IT teams.
  • Lean: Lean methodology aims at maximising value through the minimisation of waste. ITIL 4 incorporates Lean principles by focusing on improving efficiency in service management processes and ensuring that every step adds value to the customer.
  • Project Management: Practices like PRINCE2 or PMBOK can be integrated with ITIL 4, especially in areas like change management, project management, and improvement initiatives. ITIL 4 provides the service management context, while project management methodologies offer structured approaches to managing projects.
  • Information Security Management: Frameworks like ISO/IEC 27001 for information security management can be aligned with ITIL 4, particularly in managing risks, ensuring compliance, and securing information throughout the service lifecycle.
  • Governance Frameworks: ITIL 4 can be integrated with governance frameworks like COBIT to ensure that IT and business strategies are aligned, and that IT services are delivered in a way that meets the organisation's objectives and compliance requirements.
  • Quality Management Systems (QMS): Integration with QMS like ISO 9001 ensures that ITIL processes meet quality requirements and that services are consistently delivered to meet customer satisfaction.
  • Customer Relationship Management (CRM) and Enterprise Resource Planning (ERP): ITIL 4 can be integrated with CRM and ERP systems to ensure seamless service delivery and effective management of customer and resource information.

This integration capability is a key strength of ITIL 4, making it highly relevant and adaptable to various organisational contexts. By aligning ITIL 4 with other practices, organisations can leverage the strengths of each, leading to improved efficiency, effectiveness, and overall service quality.
