This is great stuff, kudos to Kevin.<p>The "looks like/is a goose" one reminds me of looking for a "market alternative" (from the book "Crossing the Chasm"). The market alternative is how potential customers <i>presently</i> deal with the problem the new product solves, and it has a name and an existing budget. This helps to communicate what the product is to the customer.<p>If it's hard to find such a market alternative, it's a sign that the product isn't ready to 'cross the chasm' into the mainstream - that is, it
won't be attractive to <i>pragmatists</i> (who just want a percentage improvement on existing methods, with minimal change). It's still in the non-mainstream pre-chasm realm populated by <i>techies</i> and <i>visionaries</i> (who think the tech is cool in itself, or who can see a new way to use it to make money, respectively).<p>It might also be that the target market selected isn't suitable, i.e. there might be another application of the technology and for another group of customers, for which there is an existing "market alternative".
