ITIL is a framework for effective IT service management (ITSM) that provides real value to customers and businesses. It consists of different stages, each of which includes a set of relevant processes. One of these processes is change management, which is part of the service transition phase and recommends a process flow for evaluating, planning, and implementing a specific change request. The main purpose of ITIL change management is to ensure that the execution of changes does not disrupt ongoing operations.
The ITIL change management process acts as a guardian that authorizes each changelog before moving on to the version management phase. IT and DevOps teams use it effectively on a daily basis to manage new change requests and plan implementation. There are various use cases in which ITIL change management can be used, such as the correction of security errors. It is beneficial for any company, regardless of its size and nature. Change management solves multiple use cases and takes advantage of the process flow to improve efficiency and mitigate risk.
An Emergency Change Advisory Board (ECAB) can be established to meet quickly when emergency changes arise; this training should be included in the policy. There will always be some change requests waiting to go through the approval process, depending on the availability of the change manager or change advisory board. If a critical piece of hardware needs to be replaced immediately or if a security update must be installed this week, ITIL ensures that there is an appropriate process to help these changes take place. It is important to share the purpose and benefits of a well-structured change management process with all levels of the organization, gaining acceptance from the organization's leaders and working along the chain of command. For certain types of changes, such as major changes, the change evaluation process carries out a formal evaluation of the change and is documented in a change evaluation report. The required change category helps managers apply the correct level of scrutiny to the application.
The change manager, through an anticipated change schedule (FSC) or a change schedule, will inform all interested parties of the upcoming changes that may affect them. In ITIL 4, change managers have more freedom to structure processes aligned with business priorities. Change management interacts with other ITIL service management processes throughout the service life cycle, including problem and configuration management. A change request is typically created by the person, process, or business unit that requires the change. The information associated with the affected configuration element (CI) is also updated throughout the change management process. CMO and change management work together because the organizational structure influences the behavior of people and processes.
Service requests are met through the support service request fulfillment process and include change management processes (and possibly the vendor management process). In conclusion, ITIL change management is an essential part of ITSM that helps organizations manage new requests and plan implementation effectively. It ensures that changes are executed without disrupting ongoing operations and provides organizations with an appropriate process for critical hardware replacements or security updates. By understanding how it works and its benefits, organizations can make sure they are using it correctly.
