A butterfly in Java waves its wings and, as a result, the weather in Chicago turns nasty. But each time a consultant flaps his lips, the Butterfly Effect becomes more firmly entrenched as both a law of nature and a management axiom. The image of a tiny butterfly in some exotic locale causing weather shocks thousands of miles away has a certain intellectual appeal. The universe does not run like a clock. It's a compelling message for harried executives trying to make sense of an increasingly chaotic world.
