How to Brief a Business Consultant (And What a Good One Asks You Back)

Most consulting engagements go wrong at the start, not the middle. The brief was thin, the consultant filled the gaps with assumptions, and three weeks in, both sides discovered they were solving different problems.

The fix costs you about an hour. Here is what to prepare before you speak to any consultant, what to deliberately leave out, and, just as importantly, what a good consultant will ask you back. That second half doubles as a hiring filter: the questions you get asked in the first meeting tell you more about a consultant than their proposal will.

Describe the problem, not the solution

The most common briefing mistake is arriving with the answer already decided. "We need a new CRM." "We need a marketing agency." "We need an app."

Those are solutions, and they might be wrong. What you actually know is the symptom: quotes take too long, jobs fall through the cracks, the phone has gone quiet. Brief the symptom in plain words. Where does it hurt, when did it start, what does it cost you when it happens?

If you hand a consultant a solution, an average one will build it for you, and you will have paid professional rates to execute your own guess. A good one will ask why you think that is the answer, which is the first sign you have found someone worth paying.

What to have ready

You do not need a formal document. A page of notes covers it:

The symptom, with an example. Not "operations are messy" but "last Tuesday a customer chased a quote we had promised nine days earlier". Real examples carry more information than any summary.

What it costs you. Roughly, in lost jobs, wasted hours or rework. This number matters because it sets the ceiling on what any fix is worth, and it is how you will later judge whether the price you are quoted is fair.

What you have already tried. Including the things that failed and why you think they failed. This saves the consultant retracing dead ends at your expense.

Your constraints. Budget range, who is available to help, anything that cannot change. If the software your industry runs on is non-negotiable, say so on day one, not week four.

What success looks like to you. Even a rough version. "Quotes out the same day" gives the engagement a target. You will refine it together, but starting the conversation without one invites vague outcomes, and vague outcomes are how bad engagements defend themselves.

What to leave out

Leave out the diagnosis. You are close to the problem, which makes you the best source of symptoms and the worst source of causes. The whole point of bringing in an outside operator is a set of eyes that does not share your assumptions.

And leave out the flattering version of events. Consultants are not auditors, and the ones worth hiring are unshockable. If the books are behind, if a key person is struggling, if you have been avoiding a decision for a year, say so. Every hour a consultant spends discovering what you already knew is an hour you are paying for twice.

What a good consultant asks you back

This is the part most briefing guides skip, and it is the most useful signal in the room.

A genuine consultant responds to your brief with questions, because a one-page brief cannot contain a diagnosis. Expect things like:

• "Walk me through the last time this went wrong, step by step."
• "What have you already tried, and what happened?"
• "Who on your team feels this most, and can I talk to them?"
• "What happens if you do nothing for a year?"
• "Why fix this now, rather than six months ago?"

Notice what those questions have in common: they are attempts to understand the problem before proposing anything. That is what the first conversation is for. At NXT Innings we treat it as a diagnostic, not a pitch, and we will tell you plainly if what you need is not us.

The warning sign is the opposite: a consultant who hears your brief and responds with a proposal. No questions, no contact with the people who live the problem, straight to a scope and a price. That is not confidence. That is a template looking for a buyer. I keep a list of questions to put to any consultant before you sign, and "what did they ask me?" belongs alongside it as the other half of the test.

Where the brief goes from here

A good first conversation turns your one page into something sharper: an agreed problem, a measurable outcome, and a price for getting there. In our case that takes the form of a Play, a fixed-price piece of work with a success metric you approve before anything starts. That structure, and the operational work it typically covers, is described on our strategy and operations page.

But the brief is yours regardless of who you hire. Write it once, put every candidate through it, and compare what they ask you back. An hour of preparation, honestly written, is the cheapest protection you can buy on an engagement worth thousands.
