A few weeks ago, I published a post When Might it be OK to not Listen to the Customer with the inspiration coming from having just finished Innovator’s Dilemma by Harvard Professor Clayton Christensen.  To oversimplify the summary, it was about the distinction between sustaining and disruptive innovation.

Recently, I also came across an article on HBR titled The 4 Types of Innovation and the Problems They Solve, so it seemed appropriate to expand perspectives and dig into what the author had to say.
