I think I can add some innovation to this discussion (whichever definition of innovation you'd like) to point out the inherently illogical nature of this discussion.
Usually you only hear about innovations that are a success, failure is an orphan but success has a million fathers, etc. Therefore by the rules of logic all innovation leads to success. Surely by all rules of logic anything true in one way it true the other way, so all success required innovation. Given that scenario as starting conditions and rules of the game, minor engineering evolutionary improvements that none-the-less are eventually profitable, must be defined as super tiny incremental irrelevant forms of innovation, although they're really just boring gradual evolution.
Or if you really want to muddy the waters there's some fun analogies you can make between evolution vs intelligent design and mere incremental product development and actual innovation, and how both mental models seem to make their owners both really happy and extremely binary in their outlook toward the opposite.
