Timothy Zahn said this quote

There are times in every commander's life when he must yield the stick of authority to a subordinate.Sometimes the reason is one of expertise, when the subordinate has skills the commander lacks. Sometimes it is positional, when the subordinate is in the right place at the right and the commander is not. Often it is anticipated there will be loss of direct communication, which means the subordinate may be given general instructions but must then carry them out on his own initiative as the situation flows around him.No commander enjoys those moments. Most subordinates fear them, as well. Those who do no fear already betray the overconfidence that nearly always leads to disaster.But the moments must be faced. And all will learn from them, whether to satisfaction or to sorrow.
