Who should own service request management?
Assign a service owner who understands the promised outcome and can resolve cross-team handoffs. Individual delivery tasks still need their own responsible people; ownership of a dashboard is not ownership of the service.
Should we design the policy before choosing software?
Define at least the service outcome, required information, authorizer where needed, task owners, and acceptance condition first. Then check whether the app makes those decisions and exceptions usable.
What should happen to an incomplete request?
Return it with a specific question and preserve its history. Make it clear who must correct the information and when it can proceed; do not mark it rejected solely to get it out of an active queue.
What metric should a small team start with?
Start with a decision: which requests have no owner, which tasks are blocked, or which deliveries await confirmation? Add delivery-time metrics only after the start, finish, working calendar, and waiting policy are defined.
Are the service-delivery and help-desk examples one synchronized app?
No. They are separate examples for defined service delivery and unexpected employee issues. If you need a handoff between them, design the relationship and ownership rather than assuming automatic synchronization.
