In ITSM, what is the definition of 'Change'?

The definition of 'Change' in IT Service Management (ITSM) refers to any adjustment to a service or its components. This encompasses a wide range of activities, including minor updates, routine maintenance, and significant alterations, as long as they impact the service, its infrastructure, or the management of that service.

Understanding what constitutes a 'Change' is crucial in ITSM because effective change management helps ensure that modifications are systematically planned, assessed, and implemented with minimal disruption to the organization or its services. It defines a structured approach to transitioning individuals, teams, and organizations from a current state to a desired future state, which can involve enhancements, updates, and even the introduction of new services.

The other definitions described do not fit the broader scope of 'Change' in ITSM. For instance, the process of fixing an incident pertains specifically to incident management, while focusing solely on major upgrades to hardware or on the termination of a service is too narrow and does not encapsulate the full range of potential service adjustments that can occur in an IT environment.
