Business is a game, but unlike war or sport, the game of business does not require other players to fail, nor is it about how you play. Even brilliant performance won't be enough if you are playing the wrong game. The essence of business success lies in making sure you are in the right game. Two leading business gurus, Brandenburger and Nalebuff, have devised a practice-oriented model based on game theory which consists of levers, or PARTS, of strategy - Players, Added values, Rules, Tactics and Scope - which provide a systematic and comprehensive approach to getting started in the right game successfully.
