"No leader can possibly have all the answers . . . .The actual solutions about how best to meet the challenges of the moment have to be made by the people closest to the action. . . .The leader has to find the way to empower those frontline people, to challenge them, to provide them with the resources they need, and then to hold them accountable. As they struggle with . . . this challenge, the leader becomes their coach, teacher, and facilitator. Change how you define leadership, and you change how you run a company."
