Information Technology Infrastructure Library, ITIL is defined as a framework with a set of best practices for delivering efficient IT support services. It enables organizations and individuals to deliver cost-effective IT Service Management, ITSM aligned with business vision, strategy and growth and acts as a single point of contact between service provider and end users. While ITSM helps businesses to achieve their mission and vision with the right mix of process, technology and people, ITIL guides the way IT services are managed and delivered. Digital transformation and technology initiatives are guided by the best practices of ITIL. Companies adopt ITIL to realize their business benefits faster with defined processes and enabled by the right technology. ITIL aims for resource optimization and reviews existing processes continuously to improve. It also acts as a business partner for organizations to adopt only those practices that are relevant for them.
ITIL, since its inception in 1980, has continuously evolved into many versions and currently has 5 books. ITIL was first developed by the British government's Central Computer and Telecommunications Agency (CCTA) in the 1980s. Over the years, it has undergone multiple revisions that aim towards business alignment and improved efficiency. The first ITIL book was published in 1989 followed by a V2 in 2000. While V3 came out in 2007, a more up-to-date variant of V3 was published in 2011. The latest edition of the ITIL book is expected to release later this year and it is expected to cover methodologies like Devops, agile and lean.

Businesses implement new projects or applications on a day to day basis. It is important to analyze risk and impact before carrying out the planned activities. Based on the risk and impact, change approvals are planned including all relevant stakeholders. Change management records every detail of change that is requested for better tracking and audit. Change management is crucial for an organization in order to effectively deploy new implementations without any downtime. Post implementation review is done to keep things in control.
Business users expect smooth business operations without any disturbance. However, in reality it is a challenge to achieve with the available complex infrastructure components and applications. Proactive approach to incident management deflects redundant tickets and also eliminates major incident occurrence. Automation handles ticket classification and assignment so that service desk agents focus on higher priority activities. ITIL Incident management works in close association with Configuration Management Database, CMDB to link the asset related to the incident.
Repetitive issues are handled by Problem management team to analyze the root cause and find a permanent fix. Problem manager performs the Root Cause Analysis, and suggest a temporary workaround until permanent solution is deployed. Proactive problem management is adopted by many organizations to prevent any potential damage caused by major outages and ensure service availability. It is recommended to understand the difference between incident and problem management to assign clear roles and responsibilities.
