Yeah, the book goes into a LOT more detail. It's actually a detailed step-by-step roadmap for how to go from and hypothesis / guess, to a validated product idea with a defined, existing and profitable market. It's oriented mostly towards enterprise software scenarios, but he does point out where the same ideas can be applied to consumer products to some extent.
Honestly, if enterprise scenarios are on your roadmap at all, I think you may find it to be one of the most valuable books you'll ever read. I'm just now in the process of putting his process into action for my own startup, and I'm solidly convinced that this is The Way To Go (esp. for enterprise software, which happens to be what I'm doing.)
