Paid outside expertise engaged to answer a question the business cannot answer from inside it. Six categories cover nearly all of it, and the test for whether you need one is whether your gap is capability or capacity.
The term is broad enough to be close to meaningless in marketing, which is why most pages on it say nothing. Here is the version with edges on it.
The six categories
| Category | The question it answers | Typical output |
|---|---|---|
| Strategy | Where should we compete, and what should we stop doing | A set of choices with the reasoning attached |
| Operations | Why does this process cost what it costs | A redesign, usually with a measured baseline |
| Financial | What do the numbers actually say | A model, a diagnosis, sometimes a restructure |
| Technology | What should we build, buy or retire | An architecture or a selection recommendation |
| People and organisation | Why does the structure produce this behaviour | A design change, rarely a training programme |
| Transaction | Is this acquisition, sale or raise sound | Due diligence and a position |
Most engagements are one of these wearing the language of another. A technology selection sold as a strategy project is common, and it is worth being clear which you are buying, because the skills are not interchangeable.
The test: capability or capacity
The single most useful question before engaging anyone.
Capacity gap. Your team knows what to do and does not have the hours. A consultant is an expensive way to buy hours, and a contractor, a temporary hire or a reprioritisation will be better value. Consulting rates are priced for judgement, and paying them for execution is the most common way firms feel burned by consultants.
Capability gap. Nobody internally has done this before, or the honest answer is politically difficult to say from inside. This is what outside expertise is genuinely for. The distance is the product as much as the expertise.
A third, less often named: credibility gap. Sometimes the business knows the answer and needs it said by someone the board will believe. That is a legitimate reason to engage a consultant, and it is worth being honest with yourself that it is what is happening, because it changes who you should hire.
What good looks like
The question gets rewritten. A consultant who accepts your framing of the problem without challenging it is selling compliance. The first genuinely valuable thing most engagements produce is a better question than the one in the brief.
The reasoning comes with the recommendation. A recommendation without its logic cannot be adapted when something changes, and something always changes. You end up re-engaging to re-ask.
Somebody internal owns it from day one. Recommendations delivered to a business with no internal owner have a predictable life: read, agreed with, filed.
The engagement names its own end. Including what success looks like and what happens afterwards. The drift from a finished project into unbilled or unmanaged advisory is bad for both sides.
What it costs, and why rates do not compare
Fees vary from a few thousand for a scoped piece with an independent consultant to six figures with a large firm. Comparing day rates across those is close to meaningless, because the three common pricing shapes are measuring different things.
A day rate prices time, and the risk sits with you: if the work takes longer, you pay more. A project fee prices a defined output, and the risk sits with the firm, which is why project fees carry a margin for it. A retainer prices availability rather than output, and it only works when what is included is written down.
The pricing shape tells you more about the engagement than the number does.
The part that decides whether it was worth it
The recommendation is not the product. What the business does in the ninety days afterward is.
This is where most consulting value evaporates, and it is rarely the consultant's fault. The report is sound, the room agreed, and then the commitments have no single owner, no measure, and no review until the quarter ends. By then the context has moved and the recommendations are being judged against a world that no longer exists.
Which is a solvable problem and a dull one: one named owner per commitment, a measure that can fall, and a fortnightly review rather than a quarterly one. The mechanics are in why strategy execution fails.
For consulting firms that want the work to survive the handover, GPS for Professional Services gives each client a workspace holding their plan and their progress, so the recommendations become commitments with owners rather than a document, and the firm can see across every engagement at once.
