Should the firm that diagnoses our AI opportunity also build the solution?

This is the sharpest question an executive can ask in a first meeting, and very few ask it.

The concern is not dishonesty. It is structure. When the same firm diagnoses and builds, the diagnosis is upstream of their largest revenue opportunity. That does not guarantee a distorted finding, but it does mean the pressure runs one direction, and pressure that runs one direction long enough eventually shows up in the work.

There are real advantages to keeping it together. The people who examined your operation understand it, so nothing is lost in a handoff. Accountability sits in one place when something does not work. And a firm that has to live with its own recommendation is more careful about making it.

So the question to ask is not "do you also build?" It is this: tell me about a time your assessment concluded that the client should not build anything. If the answer is vague, or if it has never happened, you have learned what you needed to know. If they can name the engagement and explain what they recommended instead, the incentive is being managed.

For what it is worth, our own answer to that question includes a client who was certain they needed AI for proposal responses and got a straightforward database application instead, because it was cheaper, easier to maintain, and better for their confidentiality requirements. That is the test, and it is a fair one to put to anyone.
