Information Technology Infrastructure Library (ITIL): Definition, Explanation, and Use Cases

The Information Technology Infrastructure Library (ITIL) is a globally recognized framework that guides businesses in the management of their IT services. It is a set of detailed practices for IT service management (ITSM) that focuses on aligning IT services with the needs of the business. ITIL is designed to provide a practical, no-nonsense framework for identifying, planning, delivering, and supporting IT services to businesses.

ITIL was developed during the 1980s by the UK government's Central Computer and Telecommunications Agency (CCTA) with the aim of ensuring better use of IT services and resources. It has since been adopted by thousands of organizations worldwide, including government agencies and large corporations. It is now maintained and updated by AXELOS, a joint venture company, created by the Cabinet Office on behalf of Her Majesty's Government (HMG) in the United Kingdom and Capita plc.

ITIL Framework

The ITIL framework is based on a service lifecycle and is divided into five main stages: Service Strategy, Service Design, Service Transition, Service Operation, and Continual Service Improvement. Each of these stages is focused on a specific aspect of IT service management and contains several processes and sub-processes.

ITIL is not a one-size-fits-all solution, but rather a flexible framework that can be adapted and applied according to the specific needs and structure of any organization. It provides a structured and standardized approach to IT service management, helping organizations to avoid common pitfalls and achieve their IT objectives in a reliable, efficient, and cost-effective manner.

Service Strategy

Service Strategy is the first stage of the ITIL service lifecycle. It provides guidance on how to design, develop, and implement service management not only as an organizational capability but also as a strategic asset. It helps organizations to set objectives and expectations, identify and select opportunities, and plan for execution.

Service Strategy is all about ensuring that the organization's IT services align with its business needs and objectives. It involves defining the market, developing the offerings, creating strategic assets, preparing for execution, and coordinating actions.

Service Design

Service Design is the second stage of the ITIL service lifecycle. It provides guidance for the design and development of services and service management processes. It covers design principles and methods for converting strategic objectives into portfolios of services and service assets.

The purpose of Service Design is to design IT services, together with the governing IT practices, processes, and policies, to realize the service provider’s strategy and to facilitate the introduction of these services into supported environments ensuring quality service delivery, customer satisfaction, and cost-effective service provision.

ITIL Processes

ITIL processes are the activities, procedures, and tasks that IT organizations use to deliver and manage IT services. They are grouped into five areas corresponding to the stages of the ITIL service lifecycle: Service Strategy, Service Design, Service Transition, Service Operation, and Continual Service Improvement.

Each ITIL process is defined with key inputs and outputs, along with the specific objectives to be achieved. The processes are interrelated and are designed to provide a holistic approach to IT service management.

Incident Management

Incident Management is a critical process in ITIL. Its primary goal is to restore normal service operation as quickly as possible to minimize the impact on business operations. This is achieved by identifying, recording, analyzing, and resolving incidents as quickly as possible.

Incident Management includes any event which disrupts, or which could disrupt, a service. This includes events which are communicated directly by users, either through an interface from Event Management to Incident Management, or through the Service Desk.

Change Management

Change Management is another key process in ITIL. It aims to control the lifecycle of all changes, enabling beneficial changes to be made with minimum disruption to IT services. The primary objective of Change Management is to enable beneficial changes to be made, with minimum disruption to IT services.

Change Management is responsible for controlling change to all configurable items in an IT infrastructure, including applications, documents, equipment, networks, and systems. It is a critical process that helps organizations to maintain and improve their IT service delivery.

ITIL Certifications

ITIL certifications are globally recognized IT service management certifications that demonstrate an individual's understanding of the ITIL framework. They are awarded by AXELOS and its authorized examination institutes. ITIL certifications are available at various levels, each of which corresponds to a different level of knowledge and understanding of the ITIL framework.

The ITIL certification scheme provides a modular approach to the ITIL framework and is comprised of a series of qualifications focused on different aspects of ITIL best practice to various degrees of depth and detail. The tiered structure of the qualification offers candidates flexibility relating to the different disciplines and areas of ITIL and the ability to focus their studies on key areas of interest.

ITIL Foundation Certification

The ITIL Foundation certification is the entry-level qualification in the ITIL certification scheme. It offers a general awareness of the key elements, concepts, and terminology used in the ITIL service lifecycle, including the links between lifecycle stages, the processes used, and their contribution to service management practices.

ITIL Foundation is suitable for individuals who require a basic understanding of the ITIL framework and how it may be used to enhance the quality of IT service management within an organization. It is also suitable for professionals who are working within an organization that has adopted and adapted ITIL and need to be informed about, or contribute to, ongoing service improvement.

ITIL Intermediate Certification

The ITIL Intermediate certification is the next level of qualification in the ITIL certification scheme. It is divided into two categories: Service Lifecycle and Service Capability. Each category has several modules, each of which focuses on a specific aspect of IT service management.

ITIL Intermediate is suitable for those who need to understand the ITIL framework in depth, or those who wish to specialize in a specific area of ITIL. It is also suitable for professionals working in an IT service management capacity within an organization that has adopted and adapted ITIL and need to be informed about, or contribute to, ongoing service improvement.

ITIL Use Cases

ITIL is used by organizations worldwide to establish and improve capabilities in service management. ITIL best practices are applicable to any organization that provides services to a business, including public and private companies, government entities, and non-profits.

ITIL provides a robust framework for identifying, planning, delivering, and supporting IT services that can be adapted and applied to all business and organizational environments. It helps organizations to achieve predictable service levels and to optimize their service delivery processes.
