Eric McNulty, associate director of Harvard’s National Preparedness Leadership Initiative, studies how managers successfully lead their companies through crises such as the Deepwater Horizon oil disaster and the Boston Marathon terror attack. He identifies the common traps that leaders fall into and shares how the best ones excel by thinking longer-term and trusting their teams with operational details. He also finds that companies that put people ahead of the bottom line tend to weather these storms better. McNulty is a coauthor of the book “You’re It: Crisis, Change, and How to Lead When It Matters Most” and the HBR article “Are You Leading Through Crisis… Or Managing the Response?”
