You have to lead from everywhere. Interviewed by Scott Berinato

When responding to a complex, fast-moving crisis, leaders must constantly adapt their mental models and create a "unity of effort." argues Allen, a retired U.S. Coast Guard admiral and the national incident commander for the Deepwater Horizon oil spill. That's a much bigger management challenge than approaching the job as a military operation and drawing on unity of command, and it can require nuanced and creative strategies, such as deciding to go "off book" when standard protocol simply won't work. In this edited interview, Allen--who also brought post-Katrina New Orleans back from the brink of anarchy and headed the Coast Guard's response to the September 11 attacks along the eastern seaboard-stresses the need to lead both from headquarters and on the ground. He discusses how the phenomenon of publicly available, real-time information has affected crisis management in recent years, addresses the challenges of managing multiple public and private stakeholders, and shares his thoughts on how to lead when an anxious public is counting on success.
