It would be great to have the ability to have more than 1 Approver at each level in a Sequential Change Mangement policy.
Some policies we have created either require more than one approver or a certain number out of x before it can be moved on to the next phase.
An example would be:
Change Request Policy
Approval Level 1
# of approvals required = 1
Approval Level 2
# of approvals required = 2
This would allow for more flexibility in the approval process as well as create approval tiers. It also allows you to have a back-up approver in place should the primary be unavailable or away so the change is not left stuck and awaiting their return since you could have another approver listed.
