The term Change is has many meanings, however the best definition of a service change is:
“Any alteration in the state of a Configuration Item (CI). This includes the addition, modification or removal of approved, supported or baselined hardware, network, software, application, environment, system, desktop build or associated documentation.”
It is important that every organization defines those changes which lie outside the scope of their service change process (such as operational or business process and policy changes).

“Remember: Not every change is an improvement, but every improvement is a change!”
