You need to understand that informed intuition, rather than analytical reason, is the most trustworthy decision-making tool to use. - Geoffrey Alexander Moore

Just as in literature, where memorable characters like Hamlet or Heathcliff or even Dirty Harry stand out and become symbols for a larger segment of humanity, so in marketing can whole target-customer populations become imagined as teenyboppers, yuppies, pickups and gun racks, or the man in the gray flannel suit. These are all just images—stand-ins for a greater reality—picked out from a much larger set of candidate images on the grounds that they really “click” with the sum total of an informed person’s experience. These were, in short, the memorable ones.

First, please note that we are not focusing here on target-market characterization. The place most crossing-the-chasm marketing segmentation efforts get into trouble is at the beginning, when they focus on a target market or target segment instead of on a target customer.

Entering the mainstream market is an act of burglary, of breaking and entering, of deception, often even of stealth. Mapping out a global assault plan, attacking on all fronts at once, may work for massively intimidating market leaders who already have troops in place throughout the world, but it is just plain silly for stripling challengers. Instead, we need to pick our spots carefully, attack fiercely, and then dig in and hold.
