How to hire
How to hire interim COOs, and the best places to look
Interim operating leaders are usually between assignments for weeks, not months. Have the brief ready before you search.
The best places to hire interim COOs are interim specialists, executive recruiters with an interim desk, and professional bodies for interim managers. Platforms list availability; check operating experience yourself.
For a remote interim COO, decide which sites and teams need them in person. Operations is rarely fully remote.
The working pattern
What changes when the COO is interim?
Interim COOs take the operating seat full-time for a defined transition. The assignment ends with systems, decisions and ownership handed on, not just a date.
The illustrative brief: an integration after an acquisition. Two operations must become one within a year. The existing operations director runs one site and has no capacity for the integration.
The appointment owns: The interim COO leads the integration plan and owns the combined operating decisions.
Another owner retains: The CEO keeps the permanent structure; site managers keep daily delivery.
The case is illustrative; it does not describe a Fractional Quest placement.
