How to scope a consulting brief before you hire anyone

Most consulting engagements that go wrong do not go wrong because the consultant was bad. They go wrong because the brief was vague. The client had a feeling that something needed to change, hired someone to fix it, and then spent the first three weeks of the engagement figuring out what the actual question was. That time is expensive and it is avoidable.

Start with the decision, not the problem ¶

The most useful thing you can put in a brief is the decision you are trying to make. Not the background, not the history, not the context. The decision. 'We need to decide whether to expand into a new market by the end of Q3' is a brief. 'We are thinking about growth' is not.

Once you have the decision, the rest of the brief writes itself. What information do you need to make it? Who needs to be involved? What does a good outcome look like? These questions are easy to answer when you start from the decision.

Define what done looks like ¶

A brief without a definition of success is a brief without an end date. Before you hire anyone, write one sentence that describes what you will have at the end of the engagement that you do not have now. A written strategy. A revised pricing structure. A ranked list of operational fixes. Something concrete.

If you cannot write that sentence, the brief is not ready. That is useful information. It means you need to spend more time on the problem before you spend money on a solution.

Be honest about your constraints ¶

Budget, timeline, and internal capacity are not embarrassing details to hide until the second call. They are the parameters that determine whether a given engagement is possible. A consultant who does not know your budget will propose something that does not fit. A consultant who does not know your timeline will plan for more time than you have.

Tell the consultant your constraints early. A good one will tell you honestly whether they can work within them. If they cannot, you have saved each other several weeks of misaligned expectations.

One question to ask before you sign anything ¶

Ask the consultant what they will not be able to tell you by the end of the engagement. Every scoped project has limits. A consultant who can answer that question clearly has thought seriously about what they are taking on. One who cannot is either overconfident or has not read the brief carefully enough.

A well-scoped brief is not a bureaucratic exercise. It is the fastest way to get from a problem to a useful answer.
