The peril of a potent resource position is that success then arrives without careful ongoing strategy work. Own the original patent on the plain-paper photocopier, or own the Hershey’s brand name, or the Windows operating system franchise, or the patent on Lipitor, and there will be many years during which profits will roll in almost regardless of how you arrange your business logic. Yes, there was inventive genius in the creation of these strategic resources, but profits from those resources can be sustained, for a time, without genius.
