Hire full time when operations is a permanent, full seat. Bring in a fractional COO to build the operation, prove it and hand it over. Most companies need the second before they can judge the first.
Is it a fit?
Permanence
Operations is a seat somebody holds for years, not a transition.
A full week
The work only a COO could do fills a week, counted .
Supervision
Somebody senior sets direction and reads the output every week.
Start here. A few questions return how much of the week runs through you.

What you get
The job is permanent, or it is a transition
A full time COO is right when operations is a standing seat somebody holds for years. A fractional one is right when the job is to build the system and hand it to the company.
There has to be a week of it
A senior operator with three days of real work and two of invented work leaves inside a year. Count the actual load before anybody writes a job description.
Somebody has to supervise it
A COO reports to a founder who sets direction and reads the output. Where that attention does not exist the hire drifts, and the founder ends up managing the manager.
The knowledge has to survive the ending
A hire holds the operating knowledge and can leave with it. A fractional COO writes it into your systems, because the engagement is built to end. Decide which outcome you want before you choose.
A COO hired into chaos inherits it
With nothing written down, a new COO spends the first year rebuilding the operation inside their own head. That is the most expensive way a company ever documents itself.
The order that usually works
Define the operation, run it long enough to prove it, then hire into a seat that already has a shape. At that point the job description writes itself and the hire can be judged in month one.
How to decide, in order
Start with whether the job ends. Operations that will need a senior owner for the next five years is a hire. Operations that needs building, proving and handing over is a fractional engagement, and those are not the same job.
The knowledge question is the one people skip. A hire builds the operating system inside their own head, which is efficient right up until they leave. A fractional engagement is built to end, so it writes the system down on the way through.
Earlier than a COO, many founders start with a fractional chief of staff.
Questions we get
Is a fractional COO just a consultant?
No. A consultant recommends and leaves. A fractional COO holds the seat: approvals, vendors, handoffs and the weekly numbers, with their name on the outcome.
The test is whether decisions wait for them. If nothing waits, it is consulting.
How many days a week does it take?
Enough to hold the decisions, which for most companies is part of a week rather than all of it. The load is heaviest early and falls as the system takes over.
A day spent only on status reporting is a day nobody needed.
When is a full time COO clearly right?
When operations is a permanent senior seat, the load fills a week, and there is somebody who can supervise and retain a senior operator.
Multiple sites, a regulated operation or a large team usually meet all three.
Can we do both?
That is the common path. A fractional engagement defines and documents the operation, then a full time hire steps into a seat that already has a shape.
The handover is the point, so agree what gets written down before the work starts.
