A great marketing plan identifies where an organization is, where it wants to be, and how it will get there. Most companies think they already have such a plan-but often they really have only a budget, a sales goal, or an excuse. What's the solution?

There's a far more effective option: harnessing the company's own internal brain trust to create something fresh and perfectly tailored.
