It’s not easy for big companies to innovate. As Steve Blank, Clay Christensen, and many others have pointed out, once firms reach a certain size, most of their resources (and investment dollars) are rightly devoted to executing and defending their existing business model. Moreover, the skills that are cherished and rewarded for achieving current results differ from those that aid in discovery and experimentation, both of which are needed to drive innovation. As a result, fostering a true culture of innovation in big companies is often an aspiration rather than a reality.
