CHANGE MANAGEMENT AND ITIL Change Management within ITSM (as opposed to Software Engineering or Project Management ) is often associated with ITIL , but the origins of Change as an IT management process predate ITIL considerably, at least according to the IBM publication ''A Management System for the Information Business.''1 In the ITIL framework, change management is responsible for controlling change to all Configuration Item s (CI's on the CMDB ) within the live environment, test and training environments (all environments under the control of 'ICT Operations'. It is not typically responsible for change within development projects (see below). CHANGE MANAGEMENT IN DEVELOPMENT PROJECTS ITSM Change Management is not typically responsible for overseeing changes that occur within deployment or development projects which is typically delegated to a change management process dictated by the Project Management methodology adopted for the project. However close liaison between development project managers and the Change Manager is expected and the project manager may be required to utilize Change Management for items within the production or test environments that are required for testing or release. CHANGE MANAGEMENT PROCESS OVERVIEW Change Management would typically comprise the raising and recording of changes, assessing the impact, cost, benefit and risk of proposed changes, developing business justification and obtaining approval, managing and co-ordinating change implementation, monitoring and reporting on implementation, reviewing and closing RFC s. ITIL defines the change management process this way: The goal of the Change Management process is to ensure that standardized methods and procedures are used for efficient and prompt handling of all changes, in order to minimize the impact of change-related incidents upon service quality, and consequently improve the day-to-day operations of the organization. Change management is responsible for managing change process involving:
Any proposed change must be approved in the change management process. While change management makes the process happen, the decision authority is the Change Advisory Board (CAB), which is made up for the most part of people from other functions within the organisation. The main activities of the change management are:
CONTROVERSIES IN CHANGE MANAGEMENT The ITIL concept of Change Management includes ''developing business justification.'' This is a broadening of scope from other concepts of Change Management, and overlaps into the concerns of IT Portfolio Management and those areas covered by the initiation phases within programme management and project management. For example, the IBM "Yellow Book" conception of Change Control (as a subset of Resource Control) was strictly concerned with the transfer of deliverables from projects into production.2 Similarly, Schiesser in ''IT Systems Management'' defines Change Management as "a process to control and coordinate all changes to an IT production environment."
