About The Course

ITIL (Information Technology Infrastructure Library) is a framework designed to standardize the selection, planning, delivery, maintenance and overall lifecycle of IT services within a business. The goal is to improve efficiency and achieve predictable service delivery. The ITIL framework enables IT administrators to be business service partners, rather than just back-end support. ITIL guidelines and best practices align IT department actions and expenses to business needs and change them as the business grows or shifts direction.

ITIL started in the 1980s, when data centers decentralized and adopted more geographically diverse architectures. This practice caused process and deployment discrepancies and brought inconsistent or suboptimal IT service performance into organizations.

The United Kingdom's Central Computer and Telecommunications Agency (CCTA) recognized the importance of perceiving IT as a service and applying consistent practices across the entire IT service lifecycle, so it developed the Government Information Technology Infrastructure Management methodology. CCTA released ITIL v1 in 1989.

In 2000, the CCTA folded into the Office of Government Commerce and released ITIL v2 the following year.

ITIL v3 emerged in 2007 and was updated in 2011 to include feedback from the user and training community, as well as to resolve errors and inconsistencies.

How can ITIL improve a business?

The value of ITIL can be difficult to quantify. The goal of ITIL or any ITSM framework isn't just to improve IT capabilities, but also to find ways of creating business value and solving business issues with IT. ITIL offers a comprehensive framework designed to help businesses organize their resources and processes to create new capabilities that provide business value. But ITIL isn't prescriptive it doesn't say, Use X to do Y to realize Z benefit.

Instead, ITIL casts a much wider net by offering a set of general guidelines that can be readily adapted and adjusted. When developed correctly, ITIL implementation can bring important business benefits, including the following:

  • stronger alignment between IT and business, leading to IT enabling new business services and capabilities
  • cost reductions, usually through improved resource use and
  • improved service delivery, leading to better revenues and customer satisfaction.

Because ITIL is a voluntary framework rather than an imposed standard, organizations are welcome to adopt as much of the ITIL framework as necessary and appropriate to suit the needs of the specific business. Still, the benefits of ITIL can increase as more business processes become ITIL-compliant.
