The problem with conflating a disruptive in- novation with any breakthrough that changes an industry’s competitive patterns is that different types of innovation require different strategic ap- proaches. To put it another way, the lessons we’ve he theory of disruptive learned about succeeding as a disruptive innovator (or defending against a disruptive challenger) will innovation, introduced not apply to every company in a shifting market.
