I have co-written this week’s blog entry with Tsun-yan Hsieh, who has spent the past three decades working with global leaders to help them become more effective. He is Director Emeritus at McKinsey, as well as a member of the Cue Ball Collective. Recently Tsun-yan wrote a guest blog entry on recognizing the decisive moments in leadership. This post expands on that theme and is based on leadership research he has conducted over the last five years in Asia, North America, and Europe.
