Change is vital in all types of organizations. The main focus of change is to always improve the business; and it must be able to execute change with least cost and least risk of business disruption. The study mainly focuses on change management process of Information Technology Infrastructure Library (ITIL) as there are several tools from different vendors, which support ITIL. This study will explore the similarities and differences among the prominent tools and produce comparative study on change management.
From the results of a web survey we carried out in 2006, the main challenge in IT change management from a change manager's perspective was identified as planning and scheduling of changes. This paper begins to address this problem by taking business considerations into account; this is done through a business-driven IT management (BDIM) approach. A reference architecture that follows BDIM principles is sketched; it includes a mathematical model linking IT availability metrics to business objectives. Monetary loss due to service level violations on service availability is used as the main business metric. We present a numerical illustration of how the derived metrics may support change management decisions in order to plan and schedule changes to minimize adverse business impact.
