[Y Cоrp] A week аfter yоur оriginаl conversаtion with your friend, he set up a follow up meeting over coffee.  He shared that he now is starting to think that Y Corp shouldn’t be innovating at all – at least not focus on disruptive innovation.  He has read a couple articles by Clay Christensen recently (at your suggestion), and is now convinced that Y Corp should focus on its core.  Your friend has concluded that “our company should maximize the profitability of our existing strong businesses by focusing on efficiency, productivity, and incremental innovations.  I'm thinking about getting myself off of this task force.”   a) Is your friend’s conclusion about a company such as Y Corp not pursuing disruptive innovation, correct? Is it misguided for the leadership of a strong incumbent to try and “disrupt itself”?  Why or why not?  b) What is your perspective on (i) Clay Christensen's observation that incumbents have a serious disadvantage in successfully pursuing disruptive innovations and  (ii) Gary Pisano's argument that incumbents are in danger if they do not pursue disruptive innovation?  How do you reconcile these seemingly contradictory views?  It is not necessary to summarize these authors' viewpoints (assume the reader is familiar with this literature); focus on why they have different perspectives on how companies can be successful.
