The three differ on one axis: who holds the context when it ends. An agency keeps it. A hire holds it and can leave with it. A fractional COO builds it into your systems and hands it over. Choose on whether the work is a function, a project or a gap.
Sounds like this?
“We get an account manager, never the person doing the work”
The gap between who sold it and who does it is the risk.
“Everything stops when our one person is away”
That is the cost of in house nobody prices in.
“Nobody owns the outcome, only their piece”
One owner, one number, or it drifts.
Is it a fit?
Shape
A standing function, a project with an end, or a gap.
Context
Who still has to hold the knowledge when it ends.
Load
There is enough of it to keep somebody usefully busy.
Start here. A few questions return how much of the week runs through you.

Four numbers. Shows how much work is sitting still, waiting on you.
The three models
A full time hire
Right when the work is a permanent function with enough steady volume to fill a week.
An agency
Right when the work is a specialist discipline you need continuously and never want to run in house: media buying.
A fractional operator
Right when the work is senior, intermittent, and benefits from somebody who has done it before.
A contractor for a defined build
Right when the scope has a clear end.
The question underneath the staffing question
Most staffing decisions get made from a feeling of being overwhelmed. The feeling is real and it is useful, but it is not a specification. Overwhelm tells you something has outgrown its arrangement. It does not tell you which thing, or whether the answer is a person at all.
The expensive version is hiring to absorb a queue. Work is piling up, so a role is created, and the first job description is essentially a list of things nobody else has time for. It gets filled quickly, the new person is busy from week one, and the arrangement looks like an obvious success.

Before which kind of hire, whether to hire at all takes one test and an ordinary Tuesday.
What each model is good at
Seven factors, read across. The row that decides most engagements is the third one, and it is the row that almost never comes up during the decision.
| Factor | Full time hire | Agency | Fractional operator |
|---|---|---|---|
| Best fit | A permanent function with steady volume. | A specialist discipline run continuously. | Senior judgment applied intermittently. |
| Time to useful | Weeks to months: hiring, notice period, ramp. | Days to weeks. They arrive with a working process. | Days. The method is the thing being bought. |
| Where context lives | In one person, unless you insist otherwise. | With the agency, and it leaves when they do. | Should be built into your systems. Ask on day one. |
| Depth and breadth | Deep in one thing, and deeper over time. | Deep in their discipline, narrow outside it. | Broad across operations, deep in the pattern. |
| How it goes wrong | The role becomes a queue and the person burns out. | Reporting quietly replaces results for two quarters. | It becomes a permanent dependency instead of a handover. |
| Question to ask | What outcome does this person own? | What does this account look like in month six? | What are you leaving behind, and when? |
| Exit | Notice period, plus a knowledge gap if nothing was written. | Notice period, and the tooling usually goes with them. | By design: a documented process that runs without them. |
None of the three is better than the others. They fail in different directions, and knowing the direction in advance is most of what keeps an arrangement healthy.
Five questions before you staff it
Answer these before writing a job description or taking a first agency call. They take an afternoon and they routinely change the answer.
- Is this a function, a project, or a gap?A function is permanent and has steady volume, so hire.
- Would this role own an outcome, or absorb a queue?Write the job description and look at it .
- Has anybody measured how many hours the work takes?One week of rough tallying settles most of these arguments.
- Where will the knowledge live in a year?Name the answer before the engagement starts.
- What does success look like in ninety days?If nobody can describe the ninety day picture in a sentence.
Questions we get
What does fractional mean?
A senior operator working across a defined scope on part of a week, rather than a full time employee or a project contractor. The unit being bought is judgment and method rather than hours of execution.
Is fractional just a consultant with a new name?
The difference that matters is ownership. Consulting typically ends with a recommendation. Fractional work ends with something running, documented, and handed to somebody inside the company.
When is a full time hire clearly the right answer?
When the work is permanent, has enough volume to fill a week, and owns an outcome you can name. Those three together are a real role.
How do we stop an agency relationship going stale?
Agree what would make you end it, in writing, at the start. Then review against that rather than against the monthly report. Reporting is not the same thing as results, and it is very easy to substitute one for the other.
