The everyday problem
Delegating execution does not remove the need for internal decisions. A partner may need approvals, system access, clarification, or an escalation contact. If those responsibilities are unassigned, the arrangement can create a new waiting point rather than removing work.
A practical approach
Name an internal owner for the relationship and identify the operational roles that remain involved. Define a regular review cadence and an escalation route for urgent issues. Budget time for these responsibilities when comparing outsourcing with internal execution.
Try this with your team
List the decisions a partner cannot make alone. Assign a role and response path to each before transferring the workload.
