There’s something romantic about the idea of the lone genius. The early success of GE is often attributed solely to the inspiration and perspiration of Thomas Edison. But experience and research both tell us that lasting success is built by teams that drive each other through collaboration, different skill sets and, yes, tension. It’s difficult to imagine the stratospheric successes of Steve Jobs without Stephen Wozniak or Mark Zuckerberg without Sheryl Sandberg. Edison had many collaborators and competitors who drove him, including the engineering genius Charles Steinmetz.
