"But first let me take a step back and explain my disenchantment with the currently-ubiquitous form of disruption, Clayton Christensen’s notion of disruptive innovation.  Christensen is a professor of business administration at the Harvard School of Business, describing himself as the “World’s Top Management Thinker.”¹ His webpage defines disruption as “a process by which a product or service takes root initially in simple applications at the bottom of a market and then relentlessly moves up market, eventually displacing established competitors.”² Karl Ulrich, Vice Dean of Innovation at the Wharton School of Business, situates the process in the realm of discourse, noting that the chief requirement is that incumbents are unable to respond.³ In other words, the criterion of disruption is the silencing of competitors. This concept has been taken up eagerly by academics: The 2014 annual Educause meeting focused on the topic; Utah State University offers a prize in disruption case-study writing; institutions all across the country offer classes on disruptive innovation."
