Defining Innovation first: In my mind, true innovation is high risk and low probability, but the necessity for it outweighs all other factors. Failure is to be accepted and appreciated.
Defining Open Innovation: Often times, innovation is secretive, private, and heavily protected from often imaginary threats to ownership. I have seldom seen disruptive innovation come from such restrictive setups. Innovation requires openness and collaboration. The problems that the world is facing are not secretive, private, or heavily protected. They are "wide open" and most people can plainly see what they are. Why do we often struggle to make possible solutions for these problems as "wide open" as possible? Open Innovation requires selflessness. The end result is more important than protecting someone's ego or potential financial gains. Open Innovation is also rare. It is very hard to share, especially when you believe you have a ground breaking or innovative idea. Unfortunately, most of the hardest problems facing our species in the future will only be conquered with open and collaborative solutions.
