How to handle Change Request? (Integrated Change Control)

In PMP Exam, We might get lot of questions related to Integrated Change Control and How to handle the Change Request.

I thought it would be good to share the knowledge on Change Control.

		Before Approval Scenario	After Approval Scenario
Process group	Changes Request Raised on	Approval Required for Changes?	Approval Required for Changes?	Approving Authority
Initating	Project Charter	No	Yes	Project Sponsor
Planning	Project Management Plan	No	Yes	CCB - Change Control Board
Execution	Any Documents Changes Cost, Scope and Time		Yes	CCB
Monitoring and Control	Any Documents Changes Cost, Scope and Time		Yes	CCB
Closure	Any Documents Changes Cost, Scope and Time		Yes	CCB

To be clear, 
- In initiation phase, 
  Before Project Charter is approved by sponsor, Any change request raised can be included.
  After Project is approved by sponsor, Any change request need to approved by sponsor.

Vice versa for the rest of the things as per the table given above.    

Any change request which affects the cost, scope and time baselines need to under go below process.
