I am reading Scope secion.

I saw many times that terms - Perform Integrated Change Control, about the change of scope baseline.

Reference to PMBOK -

Controlling the project scope ensures all requested changes and recommended corrective or preventive actions are processed through the Perform Integrated Change Control process

I also read PMBOK 4.5 - Perform Integrated change control, The TT doesn't mention about CCB.

So, does the Integrated Change Control process include the approval of Change Control Board (CCB)?
