@zarbspace @Hurstharrier Currently, approver role is " Approver (may be known as Senior Analyst or Senior Responsible Officer (“SRO”))

• Scrutinises the work of the analyst and assurer

• Confirms (if necessary) to the analyst, assurer and commissioner that the work has been appropriately assured "

  Do we need to add "Takes responsibility for the quality of the analytical work", or something similar?
