The approved change requests are included as an input for control quality , basically, this's in order to verify the actions we took, whether corrective or preventive, are properly implemented.
However, it's stated that these approved change requests are coming from "perform integrated change control" process which i don't understand !
If the verification is about the work we perform in order to achieve the change request ; so this should be an output of "direct and manage work"process not" perform integrated change control"
So what's the reason behind this?
