What is Change Control?
Change Control is the process that a company uses to document, identify and authorize changes to an IT environment. It reduces the chances of unauthorized alterations, disruption and errors in the system.

It has to be implemented without affecting other components of the system. This is when the change control comes handy. It helps project teams to modify the scope of the project using specified controls and policies. Change Control is practiced whenever a project is not progressing as planned.
It is mandatory that a formal document for change request is completed and reviewed in order to keep control of change requests.
