After recertification finishes, there is no customized report available from ARM to show the list of AD groups of recertification completion vs incompletion.
Admin should have a visibility to know how many are completed and how many are not completed.
Specially when the list of data owners and resource can be adjusted during the recertification, the admin should receive at least a recertification completion report.
This is crucial reference for KPI generation or the next round of recertification.
