“In Why Managers Matter, Nicolai Foss and Peter Klein have created a welcome counter to the voices who see management as the problem rather than the solution. Absent hierarchy, they teach, unfocused variety grows but lacks the value and competitive punch of focused activity. If you are struggling within the vaporous terrain of a ‘bossless’ company, get a copy of Why Managers Matter. Or, even better, give a copy to the person who should be the boss.”—Richard P. Rumelt, author of Good Strategy/Bad Strategy and The Crux

“Leaner and flatter are better, but bosses and hierarches still matter. We just have to get them right for our times in a world that is more diverse, more teamed, and more driven by empowered leadership up and down the hierarchy. Foss and Klein have compellingly made the case. Long live the principle-driven manager!”—Michael Useem, faculty director, McNulty Leadership Program, Wharton School, University of Pennsylvania, and author of The Edge

“Managers matter, and this book shows why. Using careful research, solid evidence, and a thoughtful perspective on management and organizations, Foss and Klein persuasively demonstrate that managers—and management—will remain essential to the modern economy in the twenty-first century.”—Henry Chesbrough, University of California, Berkeley; Luiss University, Rome; and author of Open Innovation
