When should I hire a fractional COO instead of a full-time COO?
Hire a fractional COO when you need operating leadership but not full-time volume, and the company already has written processes, decision limits and weekly numbers for them to run. If those are missing, fix them first. A COO of either kind becomes the new bottleneck in an owner-dependent company. Choose full-time when the work fills five days.

What a fractional COO does (and does not)
A fractional COO runs operations for part of the week. They run the weekly operations meeting, read the numbers, hold each process owner to their limits, and fix what keeps breaking.
They don't become the place where the answers live. If every question moves from the owner to the COO, the company has a new Bob. Every company has a Bob. Somebody asks how we do something, and the answer is: "just ask Bob."
Fractional vs full-time vs integrator
| Fractional COO | Full-time COO | Integrator | |
|---|---|---|---|
| Time | Set days a week or month, agreed up front | Every day | Every day |
| Fits when | The operating work fills part of the week | The operating work fills five days | You run on EOS and need one person to drive the plan |
| Runs | Meetings, numbers, process owners, fixes | The same, plus daily decisions across sites or teams | The plan the owner sets, and the meetings that track it |
| Needs before day one | Written processes, limits, weekly numbers | Written processes, limits, weekly numbers | Written processes, limits, weekly numbers |
The last row is the same in every column. That's the point.
The readiness check before you hire
- Could someone new run your top five processes from what's written down?
- Does every recurring decision have one owner and a limit on what they can approve?
- Do the week's numbers arrive without anyone pulling them?
- Is there one weekly operations meeting with a fixed agenda?
- Could the owner be gone for two weeks without the team waiting?
Mostly no: fix the foundation first, then hire. If the work can't go to a good operator without explaining it every time, it can't go to AI either. Mostly yes: count the hours of operating work in a week, and let that number choose fractional or full-time.
What to hand over in the first 90 days of a hire
- The documents: written processes, a decision authority matrix, and an org chart with one name per seat.
- The meeting: the weekly operations meeting, run by the COO, with the owner in the room.
- The numbers: a short weekly scorecard with an owner on every line.
- The limits: which decisions move from the owner to the COO, and up to what amount.
- One problem: the process that breaks most often, with the COO accountable for fixing it.
How far a COO gets depends on what was written down before day one.
What it costs
It depends on the days and the scope, so get both in writing. Compare the days you need against a full-time salary. Then add the cost nobody quotes: a senior hire spending months learning what was never written down.
Where this sits in SCOPE™ by Efficiency Sprint
- Stabilize: repair the basics.
- Codify: make the recipe clear.
- Ownership: people run it reliably.
- Pulse: AI watches and reports.
- Engine: AI acts within guardrails.
A COO hire belongs at Ownership. Stabilize and Codify come first, so the COO inherits a recipe. In one engagement, $1.2M of $1.4M in overdue receivables was collected in three months once one person owned receivables.
AI comes after that. AI scales whatever's already there.

Questions
How many days a week does a fractional COO work?
As many as the operating work needs, agreed up front. If it reaches five days and stays there, hire full-time.
Do I need a COO or an integrator?
It's the same seat with two names. Integrator is the EOS word for the person who runs the plan the owner sets. Pick the one that fits how you run the company. Both need the same foundation under them.
What should I fix before hiring?
Whatever waits on the owner most often. Write that process down, give its decisions one owner with a limit, and get the week's numbers in one place. Then the hire runs a system on day one.
How do I measure whether it works?
Count what still reaches the owner: approvals waiting, questions only you can answer, work that stops when you're out. If that count drops month over month, it's working. If it moves to the COO's desk, you have a new bottleneck.
