What is the measure of a good executive? The ability to inspire those who follow, certainly. A dedication to speaking the truth, and particularly not misleading those who entrust leadership to him. The ability to listen and to absorb information critically. Raw intelligence. Good judgment. Being a good judge of others, and being able to pick the right advisors. Being possessed of a moral anchor. All of that would figure in the common measure of leadership. But no leader will operate without making mistakes. So another critical measure of a good leader is the ability to recognize mistakes and take remedial steps to correct them; moreover, to do this in a timely way.
