Hi

1. Who approves the changes in the project? as I understood it is CCB and sponsor or higher authority is the part of CCB.
Doubt 1: Whether Project Manager also part of CCB. Yes, then how can he approve request raise by him or his team
Doubt 2: Is it this way that if he raise change request then Higher management will approve/reject, if his team member raise then he can approve/reject?

2. What is the right flow of raising change?
