One. That is the number of questions this decision actually turns on, and it is not cost, duration, or seniority, all of which are what the proposals will be organized around. It is how much decision authority you are prepared to hand over, and every other difference between these three options follows from the answer.
My vantage point on this is the buyer’s. I have hired all three, worked alongside all three, and watched each one succeed and fail from inside the client rather than from inside the firm. What follows includes a section on when the consultant is genuinely the right answer and a section on when you should hire nobody, because a comparison that never reaches either conclusion is a sales document.
Short answer: A turnaround consultant recommends and you decide. An interim executive decides, inside a defined role, for a defined period. A fractional COO decides part-time and indefinitely. Choose on how much authority the situation requires you to delegate, then let cost and duration follow. Businesses that choose on cost consistently buy the cheapest option that cannot solve their problem.
The one question the choice turns on
Ask what has to change and then ask who currently has the standing to change it. If somebody inside already does and simply lacks capacity or a specific skill, you need help. If nobody inside does, you need authority, and authority is a different purchase.
Why cost is the wrong first question
Cost comparisons across these three are close to meaningless because they are not the same product. A consultant engagement and an interim placement quoted at similar monthly numbers differ enormously in what they can accomplish, and the difference is not effort or quality. It is that one of them can end an argument and the other cannot.
Businesses that lead with budget reliably buy the cheapest option capable of producing a deliverable, discover it did not produce a change, and conclude that outside help does not work. The conclusion is wrong and the process that generated it was reasonable at every step.
The authority test
Take the three most consequential things that need to happen and ask, for each one, whether the person who would have to authorize it is willing to. Not able. Willing. In stalled businesses the authorization frequently exists on paper and has not been used in years, and that is a signal about which option you need rather than about the person.
Why duration is the wrong second question
Duration is a consequence rather than a choice. A contested decision takes as long as it takes to make and enforce, which is weeks. Building a cadence that survives its author takes quarters. Establishing a fact takes six weeks. If you start from how long you want somebody around, you will pick a duration that fits your budget cycle and then discover it does not match the shape of the work, and the correction is expensive because it happens at month five.
Why seniority is the wrong third question
Seniority is what proposals lead with because it is the easiest thing to demonstrate and the hardest to compare. Twenty years in operations tells you very little about whether the person will make an unpopular call in your building in month two, and that is the property you are actually screening for. Ask instead for two examples of a decision they made that a client did not want made. The answers separate candidates faster than any credential.
The situation we will run through all three
Hypothetical: the situation below is constructed to illustrate the comparison. It is not drawn from any business.
The facts
A manufacturer with about two hundred people and a single plant. Revenue flat for three years, gross margin down five points over the same period, a product line that has grown every year with nothing retired. The general manager is respected, has been in place a decade, and built most of what exists. Cash is adequate. There is no crisis and no date on anything.
The owner believes the business is drifting. The general manager believes the market is soft and the operation is fine. Both positions are held sincerely and neither has been tested against data, because nobody has assembled the four slopes that would settle it.
What actually has to change
Three things. Somebody has to establish whether the margin decline is mix, price, or productivity. Somebody has to retire products, which will be opposed by the person who introduced most of them. And the approval thresholds have to move, which requires the general manager to give up authority he has held for a decade.
Note the shape of that list. One item is analytical, one is a decision with a named opponent, and one is a change to the general manager’s own position. Any comparison that does not distinguish between those three is going to give you the wrong answer.
What makes this situation typical
Two features recur in almost every business at this size. The general manager is both the source of most of the accumulated decisions and the person who would have to reverse them, which is not a criticism and is a structural fact worth naming. And the disagreement between owner and operator has never been reduced to evidence, so it is being conducted as a difference of judgment between two people who respect each other, which is unresolvable by definition.
Notice what is absent. There is no crisis, no clock, and no cash pressure, which removes the option of letting circumstance make the choice for you. Businesses in genuine distress rarely agonize over this decision because the shape of the need is obvious. It is the comfortable ones that get it wrong.
The turnaround consultant
A consultant analyzes, recommends, and leaves the decision with you. That is not a weakness of the model, it is the model, and it is why the engagement can be short, defined, and comparatively cheap.
What it does well
Analysis that nobody inside has the time or the neutrality to do. A consultant can assemble four years of margin by product family, run the mix recomputation, and put a defensible finding in front of a room in six weeks, and the neutrality is genuinely valuable because the same finding presented by an insider gets discounted as positioning.
It is also the right instrument for a specific technical capability you do not have and will not need permanently. Costing methodology, pricing architecture, network modelling. Buy the skill, take the output, keep the capability question for later.
Where it fails
It fails when the constraint is a decision rather than a fact. A recommendation to retire eleven products delivered to a leadership team that could not retire one before the engagement started will not produce eleven retirements. It will produce a document, a debate, and a small number of retirements chosen for being uncontroversial, which are the ones that were costing least.
The second failure is transfer. The consultant’s operating cadence leaves when they do, because it was theirs. Any improvement that depended on somebody chasing it weekly reverts on a schedule set by the end date of the engagement.
What it costs
Less than the alternatives on the headline number and potentially more in total, because the cost of a recommendation you do not act on is the whole fee. That is the honest accounting and it is why the model gets a worse reputation than it deserves. Consultants deliver what they were bought to deliver at a high rate. Buyers frequently bought the wrong thing.
How to buy it well
Scope the output as a finding rather than as a report, and say in the engagement letter what decision the finding is meant to inform. That single sentence changes the shape of what gets delivered, because a firm producing a document optimizes for completeness and a firm producing an input to a named decision optimizes for the two or three things that decision turns on.
The interim executive
An interim holds a role, with its authority, for a defined period. They are not advising the general manager, they are occupying a seat, and that distinction is the entire reason the model exists.
What it does well
Decisions with named opponents. An interim can retire a product line over the objection of the person who built it, because they have the standing and because they are leaving, which removes the political cost that prevents an insider from doing it. That combination of authority and impermanence is genuinely unusual and it is what you are paying for.
It also works where a seat is empty or where the incumbent is departing. Filling a gap for two quarters with somebody senior is a straightforward capacity purchase and it is priced accordingly.
Where it fails
It fails when the seat is occupied by somebody who is staying. Placing an interim alongside a general manager who remains in post produces two people with overlapping claims to the same decisions, and the organization resolves the ambiguity by waiting, which costs you the quarter.
It also fails on anything requiring more than a year, because the impermanence that makes hard decisions possible also makes durable ones unlikely. An interim will not build a capability that takes three years to mature, and should not be asked to.
What it costs
The most of the three on a monthly basis, because you are paying for full presence and for the willingness to absorb the political cost of the decisions. That premium is the product. A cheaper interim who will not make the contested call is not a saving, it is a different and less useful purchase wearing the same title.
How to buy it well
Put the authority list in the agreement before the start date, not after, and have the incumbent read it. An interim engagement negotiated with the owner and explained to the operating team in week two starts from a deficit that takes a month to recover. The boundary is going to be tested in the first fortnight regardless, and it is far cheaper to have it written down when that happens.
The fractional COO
A fractional executive holds part of a role indefinitely, typically one to three days a week, with real but partial authority. It is the newest of the three models and the most frequently mismatched to a situation.
What it does well
Building something that has to persist. Cadence, reporting, decision rights, a management layer that can operate without supervision. All of those take longer than an interim engagement and none of them requires full-time presence once designed, which is exactly the shape a fractional arrangement fits.
It also suits businesses that genuinely cannot support a full-time executive at that level, which is most businesses under a certain size. Two days a week of a senior operator is a real capability and it is available to companies that could not hire the equivalent permanently.
Where it fails
It fails under a clock. Part-time presence and urgency are structurally incompatible, because the decisions arrive continuously and the person is there on Tuesdays. A business with a cash event in eleven weeks should not be buying two days a week of anything.
It also fails when the authority is nominal. A fractional executive with a title and no ability to overrule a full-time incumbent is an expensive advisor, and the arrangement will be discovered to be advisory around month four, usually by the fractional executive.
A fractional executive with a title and no ability to overrule a full-time incumbent is an expensive advisor, and everyone finds that out around month four.
What it costs
Somewhere between the other two per month and potentially the most in total, because the arrangement is open ended by design. That is appropriate when the capability being built is permanent and it becomes a problem when nobody defines what finished looks like. Set a review point at six months and again at twelve, and ask at each one whether the remaining work still requires this person.
What each one costs you in authority
The three models sit at different points on two axes that matter more than price: how long they are present, and how much of your decision-making they hold while they are.
Reading the diagram
The consultant bar is short and delegates nothing. The interim bar is medium and delegates everything inside a defined boundary. The fractional bar is long and delegates a portion permanently. Those are three genuinely different transactions and no amount of comparing day rates will surface the difference.
Where all three sit on cost
Worth saying plainly, because the diagram deliberately omits it: cost tracks presence far more closely than it tracks value. The consultant is cheapest because they are there least. That tells you nothing about which one will produce the change you need, and a comparison built on the monthly number will systematically favour the option with the least presence, which is the one least able to make a decision.
The reading most buyers get wrong
Buyers routinely read the consultant bar as the low-commitment option and the fractional bar as the high-commitment one, and it is the opposite. The consultant commits you to nothing and therefore changes nothing on its own. The fractional arrangement is easy to exit at any month and hard to exit from in practice, because by month eight the mechanisms depend on the person. Commitment here is about dependency rather than about contract length.
Running the situation through all three
Take the manufacturer described earlier and its three required changes, and the comparison resolves cleanly, which is what a good decision rule should do.
The analytical item
Establishing whether the margin decline is mix, price or productivity is a consultant task and should be bought as one. It is defined, it is finite, it benefits from neutrality, and it requires no authority whatsoever. Six weeks, fixed fee, output is a finding. The method for reading it yourself first is in how to read an underperforming P&L, and doing that before you commission anything will substantially reduce what you have to buy.
The contested decision
Retiring products over the objection of the person who introduced them is not a consultant task at any price. It requires somebody with standing who is willing to spend it, and the general manager is by construction not that person. This item is what determines the answer for the whole situation.
The permanent change
Moving approval thresholds and installing a cadence that holds is the fractional shape: it takes longer than an interim engagement, requires partial presence rather than full, and has to survive whoever built it.
So the honest answer for this situation is a consultant for the analysis and a fractional arrangement for the structural work, with the contested retirement handled by whichever of the two has been given explicit authority for that decision and nothing else. That is a more awkward answer than picking one option, and it is the correct one.
What this pattern tells you generally
Most real situations decompose into items of different types, and the instinct to solve them with a single engagement is where money gets wasted. Split the list first. Some items need a fact, some need a decision, some need something built. Buy each type from the model that fits it, in sequence, and you will spend less in total than a single engagement scoped to cover all three.
Sequencing the three items
Order matters as much as selection. Run the analysis first, because the finding determines which products get retired and therefore what the contested decision actually is. Make the contested decision second, while the evidence is fresh and before anybody has constructed a reason it does not apply. Build the structural work third, because a cadence installed before the portfolio decision will be a cadence for managing the old portfolio.
Businesses routinely run these in the reverse order, starting with the structural work because it is the least confrontational, and arrive at the contested decision a year later with the evidence gone cold.
When the consultant is the right answer
Three situations where the consultant is not only acceptable but better than either alternative.

When you need neutrality more than authority
An owner and a general manager who disagree about whether the business is drifting do not need somebody to decide. They need a finding that neither of them produced. An interim or fractional arrangement in that situation resolves the disagreement by overriding one party, which is a worse outcome than settling it with evidence, and considerably more expensive.
When the skill is genuinely technical and temporary
Costing methodology, network modelling, a pricing architecture rebuild. These are capability purchases with a defined end and no ongoing authority requirement. Buying them as an executive placement is paying an authority premium for a skill.
When you already have the authority and lack the hands
A leadership team that can decide, has decided, and simply cannot execute the volume of work in the time available needs capacity. That is the cheapest thing on this page and it is frequently what a business actually needs, and the reason it gets over-bought as something else is that admitting you need hands is less interesting than concluding you need transformation. The Harvard Business Review argument on how to turn around nearly anything holds that the diagnosis should run longer than most operators allow, and the practical version of that advice is this: spend the extra fortnight working out which of these three you actually need, because the diagnosis is cheaper than the engagement by an order of magnitude.
When speed genuinely matters more than fit
A fourth case, and it is the one where the imperfect option is the right one. If you have a clock, a consultant who can start Monday beats a better-matched interim who can start in six weeks, because in a situation with a date the calendar dominates every other consideration. Take the available option, scope it narrowly to what it can actually do, and fix the fit later.
When the work is genuinely one-off
A fifth case, and the least glamorous. Some tasks are simply projects: a system migration, a footprint study, a costing rebuild. They have a start, an end, and no ongoing authority requirement, and buying them as anything other than a scoped project is paying for a relationship you do not need.
When you should hire nobody
Two situations, and they are more common than the market for these services would suggest.
When nobody has run the internal diagnostic
If you have not counted your own constraint, logged how long a decision takes, or pulled four years of margin by product family, you are not ready to buy anything, because you cannot yet scope it. Two weeks of your own attention will tell you which of the three you need and will reduce the scope of whatever you buy. The procedure is in the two-week plant diagnostic.
When the real constraint is the person who would have to sponsor the work
This is the uncomfortable one. If the decisions that need making are decisions the sponsor has been declining to make for years, bringing in outside help does not change the sponsor. It adds a person who will spend six months discovering the same constraint at your expense, and who will then leave, having produced a document that says what everybody already knew.
When the money would be better spent internally
A third case worth considering before any of the three. The cost of a six-month engagement is frequently close to the cost of a senior internal hire, and if the capability gap is permanent, the hire is the better purchase. Outside help is the right answer when the need is temporary, when the authority has to come from outside, or when you need it faster than hiring allows. If none of those three is true, you are buying convenience.
When the owner is the one who needs convincing
Occasionally the situation is inverted: the operator can see the problem clearly and the owner will not fund the response. Outside help is a poor instrument for that, because whoever you bring in reports to the person who is not convinced. The exception is a narrowly scoped analytical engagement commissioned jointly, which produces a fact rather than a recommendation and gives both parties something neither can be accused of authoring.
How to structure whichever you choose
Four terms matter more than the rate and they are where you should spend your negotiating attention.
Named authority
Write down which specific decisions this person can make without asking, and which they cannot. Not a title, a list. Most of the failures in all three models trace to this document not existing, and it takes an hour to write.
A defined end state
What will be true when this is finished, stated as observable facts rather than as deliverables. If the engagement produces a report, name what the report is supposed to cause. If it produces a cadence, name who will be running it after the engagement ends.
An exit
Thirty days notice, both directions, from the start. A firm that resists a mutual exit clause is telling you something about their retention rate, and a client who resists it is telling the firm something too.
Transfer written into the scope
Whoever will own each mechanism afterward should be named at the beginning and should be in the room throughout. The single most common way these engagements waste money is that the capability leaves with the person, and the only reliable prevention is naming the recipient on day one.
Who owns the relationship
Name one person inside the business who owns the engagement and has the standing to end it. Engagements that report to a committee drift, because no individual has the authority to say it is not working, and the ones that report to the person whose area is being examined have a conflict built into them from day one.
Frequently asked questions
Can one person be both interim and fractional?
Occasionally, and the transition is worth planning rather than drifting into. A common and sensible pattern is a full-time interim engagement to make the contested decisions followed by a fractional arrangement to hold the changes. Structure it as two agreements with a defined switch point, because the authority is different in each phase and leaving it ambiguous produces a fractional executive still being treated as the decision maker.
How do you compare quotes across the three models?
You do not, at least not on price. Compare them on which of your required changes each one can actually deliver, then price only the options that clear that bar. The arithmetic for pricing whichever you choose is in the cost guide.
Does seniority matter more than model?
No, and this is where buyers most often go wrong in the other direction. A very senior consultant still cannot make your decision, and a moderately experienced interim with clear authority can. Model determines what is possible. Seniority determines how well it is done inside that boundary.
What if the general manager objects to any of the three?
Treat the objection as information rather than as an obstacle. A general manager who objects to a consultant is usually objecting to being audited, which is worth discussing. One who objects to an interim is objecting to losing authority, which is the actual decision in front of you and should be made explicitly rather than resolved by procurement.
So the question was which of the three you should hire, and the answer is that you should decide how much authority the situation requires you to hand over, and then buy the model that matches. Cost and duration are outputs of that choice, not inputs to it.
