Hal Gregersen, executive director of the MIT Leadership Center at Sloan School of Management, says too many CEOs and executives are in a bubble, one that shields them from the reality of what’s happening in the world and in their businesses. The higher you rise, the worse it gets. Gregersen discusses practical steps top managers can make to ask better questions, improve the flow of information, and more clearly see what matters. His article “Bursting the CEO Bubble” is in the March-April 2017 issue of Harvard Business Review.
