Leaders Must React.

To be successful, CEOs must articulate a compelling vision, align people around it, and motivate them to execute it. But there’s one thing that can make or break them: how they respond in real time to unforeseen events.

That’s a big proportion, and not all those problems merit a leader’s attention.
