"Another method you say you studied is of great interest to me for reasons I'll not go into. It is gap analysis, especially the idea of maps. Several of our best divisions produce and sell services. Is the gap map method applicable to services? Could you please take, say, the college education "market" and draw up a product map for it? I understand it can be done by a manager at a desk, although, of course, it wouldn't be nearly as accurate as if we had all the technical da¬ta, and so on. But could you try?"
