Introduction

ITIL is a subconcept of IT service management in the most simplified form. The IT infrastructure library is a collection of services and the best practices enterprises could use to enhance their IT service management processes. ITIL originated in the United Kingdom in the 1980s by the UK central computers and telecommunications agency.

ITSM was a sunrise concept and not very widely popular during its inception, and ITIL consisted of only 30 books. With continuous development, ITIL now consists of various mixes of the best practices and requires individuals to be certified to understand ITIL and its five lifecycles. ITIL now runs on ITIL v3 and ITIL v4 due to its phenomenal rate of expansion. Throughout this write-up, we will be discussing the main feature(s) that made ITIL one of the most popular frameworks under ITSM.

Definition of ITIL

ITIL is an infrastructure that provides a set of best practices for IT services. It gives accurate guidance and information on which mix of services would fulfill their requirements. It is also the top grade in quality. ITIL is divided into five life cycles: service strategy, service design, service transition, service operation, and continual service improvement.

What is ITIL?

ITIL is a concept complementary to ITSM. Both of them work towards ensuring that the right people and services are used in the right place to ensure that the businesses achieve their corporate goals and please their customer base. ITIL particularly focuses on providing the best tools, while IT service management focuses on properly allocating these tools in the organization. ITIL mainly gained its popularity and legitimacy in 2005 when it was sanctioned and incorporated into ISO 20000 when companies began to consolidate ITIL with ITSM. This was done to fulfill their customer demands for IT services in the best possible way, both profitably and productively.
