I loved this response until the end. When the absolute cost is actually really low relative to the cost of the analyst's time then skip the expansive analysis, use a reasonable heuristic and be done. I get frustrated with analysts who are so caught up in their analytic prowess and technique that they lose sight of the business context and basic ROI. Despite my objection at the end, I really did like this example as a way to explore a person's ability to ask good questions.
