The intensifying competition and demand for high performance are pressing organizations to become more flexible, more results-focused, and more fast-acting. Companies are finding that such initiatives require effective leadership and a supportive culture, and this has become all the more critical in an era of greater uncertainty and change. The challenge is to build effective leaders and well-led teams throughout the organization, and that requires a capacity to think strategically and act decisively. Drawing on challenging moments when difficult decisions were faced by company managers, corporate leaders and even mountaineers on Everest and firefighters in the wilderness Michael Useem identifies what it takes for making timely calls when leadership matters most. Michael Useem is Professor of Management and Director of the Center for Leadership and Change at the Wharton School, University of Pennsylvania. He is author of several books on leadership and decision making, including The Go Point: When Its Time To Decide; The Leadership Moment; and Investor Capitalism. He is co-editor of Learning from Catastrophes, and co-author of The India Way: How Indias Top Business Leaders Are Revolutionizing Management. He has presented programs on leadership and decision making with a wide range of companies and organizations in the U.S. and abroad.
