Peter Scoblic, cofounder and principal of the consultancy Event Horizon Strategies, says that too many companies are short-sighted in their strategy-making and don't effectively plan for different potential futures. Using examples from the U.S. Coast Guard, he explains how thoughtful and ongoing scenario planning exercises can help organizations decide which investments will allow them to thrive in varying circumstances and navigate many types of crisis. Scoblic is the author of the HBR article "Learning from the Future."
