“Innovations, whether of product, process, or market, always move through two quite different stages. First, someone has to come up with the new idea. Then someone (often someone other than the idea imaginator) has to refine, focus, and implement that idea. And most of the resources are applied during this latter implementation period (…) in many cases, the innovator is simply adapting someone else’s invention to a different set of circumstances.”
