At least in my line of work, the big gist of that question is: "Can this person summarize a technical issue in a comprehensible way for the audience? e.g. So that it could be passed through various sales teams and project managers, but is still sensible when it lands in the client engineer's inbox?"

The correct answer starts along the lines of "How hard should I geek out?"
