Explain the concept of change management.

What will be an ideal response?

Change management refers to a methodology for making modifications to a system and keeping track of those changes. In some instances, changes to network or system configurations are made haphazardly to alleviate a pressing problem. Without proper documentation, a future change may negate or diminish a previous change or even unknowingly create a security vulnerability. Change management seeks to approach changes systematically and provide the necessary documentation of the changes.
