The Art of War

The Art of War is a Chinese military treatise of thirteen short chapters, traditionally attributed to Sun Tzu and probably compiled in the fifth to third centuries BCE. It addresses the conduct of war at the level of strategy and statecraft rather than tactics, and its brevity and aphoristic form are why it has been applied so widely outside military contexts.

The central position is that war is costly and that the best outcome is achieving the objective without fighting. Sun Tzu argues that prolonged campaigns exhaust the state, that the supreme skill is subduing the enemy without battle, and that a general should attack the enemy's strategy first, then their alliances, then their army, and only besiege cities as a last resort.

The operational chapters cover the assessment of five factors before any campaign, the importance of knowing both yourself and your opponent, the use of deception to shape what the enemy believes about your position and intentions, the choice of ground, the value of speed over perfection, avoiding strength and attacking weakness, and the use of spies, to which he devotes an entire chapter and which he justifies on the grounds that information is cheaper than casualties.

He also states that a general must have the authority to disregard the ruler's orders when the situation on the ground requires it, which is one of the earliest statements of delegated command. The business application is often superficial, since competition and warfare differ in whether the objective is destruction. The text is short enough to read in an hour and dense enough to require several passes. Translations vary considerably. Read it for the emphasis on assessment before commitment and on winning through position rather than through confrontation.
