The question for managers is what to do. For that, Clausewitz may be more useful. Clausewitz was able to characterize war as chaotic 200 years ago. It was by no means clear at the time that business, which in its modern sense was in its infancy, shared these characteristics. That was about the time that battles had grown so big that no single individual was in a position to control them directly. Wellington was one of the last to do so at Waterloo.
