The pitch for cross-industry experience is simple: patterns repeat, so someone who has seen a problem in four fields spots it faster in a fifth. I believe that. But it only holds for a smaller set of problems than the pitch usually claims.

Cases where you should hire a specialist instead:

The problem is inside one function and the function is technical. If your question is which modifier codes a specific payer rejects and under what circumstances, hire someone who has billed that payer for a decade. They will be faster and more accurate than I will, and it will not be close.

The problem is regulatory. Compliance questions have correct answers that are jurisdiction-specific and change. Pattern recognition is the wrong tool. Expertise is the right one.

You already know what the fix is. If the diagnosis is settled and the work is execution, you need capacity or a specialist implementer, not analysis. Paying for a diagnostic engagement when you have already diagnosed it is a waste, and I will tell you so in the first call.

The problem is people-specific rather than process-specific. If one team is struggling and the difference is a manager, that is a management problem. Process work will produce a nicely documented process that does not address it.

Where the cross-industry angle actually earns its cost:

Problems that sit between two functions, where each side accurately reports a failure caused by the other, and neither can see the transfer because for both of them it happens at the far end.

Situations where the reported problem has resisted several reasonable attempts. Repeated failure of sensible fixes is usually evidence the problem is misstated, and restating it benefits from someone with no stake in the previous statement.

Cases where the same symptom has appeared in several unrelated parts of the business, which suggests a structural cause rather than a local one.

This is a smaller market than “operational improvement,” which is the point. The alternative is to be vague about fit, take the engagement, and produce a report that mostly restates what the client already knew.
