A CEO’s ability to perform effectively is so closely tied to their ability to form a clearly articulated vision, evangelize the vision and then to execute on their vision, that no real discussion on executive leadership should take place without an emphasis on vision. "Put simply, I believe that leadership absent vision is a train-wreck waiting to happen. In fact, I’d go so far as to say that you simply cannot decouple the two without causing an organizational implosion. ...However worse than the CEO with no vision, is a CEO with the wrong vision. These CEOs can often go undiscovered for great lengths of time ."
