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.
In the ITIL framework, Change Management is a part of "Service Transition" - transitioning something newly developed (i.e. an update to an existing production environment or deploying something entirely new) from the Service Design phase into Service Operation (AKA Business As Usual) and aims to ensure that standardised methods and procedures are used for efficient handling of all changes.
Change Management is a process used for managing the planned deployment of alterations to all configuration items in the configuration management database, (or "CIs" in the CMDB) that are a part of a business's live ("production") and test ("UAT") environments along with any other environment that a business wants to have under Change Management - generally all environments that are under the control of 'ICT Operations'). It is not typically responsible for change within development environments (see below).
A change is an event that is:
- approved by management
- implemented with a minimised and accepted risk to existing IT infrastructure
- results in a new status of one or more configuration items (CIs)
- provides increased value to the business (Increased Revenue, Avoided Cost, or Improved Service) from the use of the new or enhanced IT systems.

Famous quotes containing the words information, technology and/or library:
“So while it is true that children are exposed to more information and a greater variety of experiences than were children of the past, it does not follow that they automatically become more sophisticated. We always know much more than we understand, and with the torrent of information to which young people are exposed, the gap between knowing and understanding, between experience and learning, has become even greater than it was in the past.”
—David Elkind (20th century)
“Technology is not an image of the world but a way of operating on reality. The nihilism of technology lies not only in the fact that it is the most perfect expression of the will to power ... but also in the fact that it lacks meaning.”
—Octavio Paz (b. 1914)
“... the subjective viewpoint is the only one to use regarding a library. Your true library is a collection of the books you want. You may have deplorably poor taste or bad judgment. Never mind. Correct those traits before you exchange your books.”
—Carolyn Wells (1862–1942)
