>>This is a brilliant idea, and after you explore it (using, for example, the lean methods which only evolved 10 years later, because you're a visionary), you decide that this is worth pursuing, it has a lot of market potential.
I do hope that was tongue in cheek... Those "lean methods" have been around forever; What's happened in the last 10 years is that they've been packaged and sold.
I think what you're saying is true from a certain perspective, but I also think that a lot of great progress comes from cross pollination of ideas. If field A solves a problem using method X, but field B has never applied method X then someone who makes that connection and applies X to B can start a mini-revolution in field B. New is pretty relative in that sense, especially if you reflect on Solomonic wisdom: "There is nothing new under the sun."
Maybe it's more helpful for product development teams in mid-size or larger firms... In the realm of bootstrappers & hustlers, most of the advice is SOP, just re-branded.
