My greatest management discovery through the transition was that peacetime and wartime require radically different management styles. Interestingly, most management books describe peacetime CEO techniques and very few describe wartime. For example, a basic principle in most management books is that you should never embarrass an employee in a public setting. On the other hand, in a room filled with people, Andy Grove once said to an employee who entered the meeting late, “All I have in this world is time, and you are wasting my time.” Why such different approaches to management?
