TOPIC: Evaluate C/R before submitting it by PM

Hi,
I am not sure whether PMI philosophy asks the PM to evaluate the impact of C/R before raising it or after? i.e. the PM is part of the CCB, so shall he/she evaluate the impact before raising the C/R or after if it will come from his/her side?
I think If it is not by his/her side, i.e vendors, or stakeholder, it is clear that it will be part of the CCB review .
But if it is by PM, he /she should evaluate the impact (scope/cost/schedule/risk) before raising the request, is not?

Hi Mohamad, I would (in real life) understand the impact of the change before raising the change request. Otherwise, it can't be discussed, approved or rejected as we won't know what the implications would be. Someone can ask for a change at any point, but I wouldn't take it to the CCB without knowing what the impact would be.
