Configuration management system

For example, if any of your project's approved change request need some project's design document to be updated. Through configuration management activities, you can ensure that updates are correctly implemented. In fact all the impacted components got the required changes.

As per PMBOK5, page # 96

Configuration control is focused on the specification of both the deliverables and the processes; while change control is focused on identifying, documenting, and approving or rejecting changes to the project documents, deliverables, or baselines.

Some of the configuration management activities included in the Perform Integrated Change Control process are as follows:
