Consistency becomes difficult to manage informally
Local managers may interpret deadlines, documents and escalation differently. A shared service model can define the same core workflow, show each location's status and identify exceptions. The business should still decide which approvals remain local and which are centralized.
Location-aware support matters
Ask how the provider handles different states, worker groups, time systems and manager permissions. Reporting should show patterns by location without exposing confidential data unnecessarily. Generic nationwide coverage is less useful than a clear process for the locations named in the scope.
