Sun Tzu also said:
“If the instructions and words of command are not clear and distinct, if orders are not thoroughly understood, then the general is to blame.” He then repeated the explanations several times. This time he ordered the drums to signal ‘left turn,’ and again the women burst into laughter.
Then Sun Tzu said, “If the instructions and words of command are not clear and distinct, if orders are not thoroughly understood, the general is to blame. But if the commands are clear and the soldiers disobey, then it is the fault of the officers.” He immediately ordered the women who were at the head of the two troops to be beheaded.
Now the drums were sounded and the drill began. The women performed all the maneuvers exactly as commanded. They drilled perfectly in precision and did not utter a single sound.
Maybe he was onto something...
