Scenarios Planning — An Ancient Art

The origins of scenario planning are ancient. Chinese military strategist Sun Tzu in "The Art of War" and Julius Caesar in "Commentaries on the Gallic War" both talk about the importance of considering unexpected possibilities and making contingencies for them. But scenarios really came into fashion in the 1940s and 1960s when the Pentagon and the Kremlin used early computers and game theory to plot various forms of Mutual Assured Destruction with nuclear weapons.
