Look for evidence of an unmanaged gap
Late tasks, repeated corrections, missing records, inconsistent manager decisions and dependence on one person are stronger signals than headcount alone. Determine whether the problem requires training, better systems, another internal hire or outside support.
Use the smallest effective solution
Selective outsourcing can cover a specific process, while broader HRO may fit several connected gaps. Compare control, service coverage, cost, implementation and continuity. Do not buy a comprehensive package merely because risk-focused marketing makes in-house work sound unsafe.
