Validated Changes

Can anyone explain why the validated changes from the control quality process are sent to the Monitor and Control Process??
And is it not required to be updated in the change log?

Its Good Idea to think.  You are correct.

According to PMBOK  4.4.14. stating that " ...A Validated Change provides the necessary data to confirm that the change was appropriatly executed....".  This is talking about raw data i.e. work performance Data.   But, this information already considered in Control Quality then produced Work Performance Information.  The same WPI already taken as INPUT to M&C.   I think this Validated Change data considered double or something else purpose.

Please explain someone?

Thanks a lot to Chullan88.




Hoping for someone to clarify...
