Specifying too much detail actually shakes confidence and creates uncertainty if things do not turn out as anticipated. Going into too much detail makes a senior commander a hostage to fortune, because in a rapidly changing environment, the greater the level of detail, the less likely it is to fit the actual situation. It also creates uncertainty about what really matters. Far from overcoming it, a mass of instructions actually creates more friction in the form of noise, and confuses subordinates because the situation may demand one thing and the instructions say another.
