In the face of ever more complex societal challenges, this book provides an essential new model for transforming the public sector and getting things done. Pandemics. Climate change. Refugee resettlement. Global supply chains. We face a new generation of complex problems that stretch across the public and private sectors and flow over organizational boundaries. To meet the moment, we need a fresh, new approach that strengthens institutions and government agencies by breaking free from organizational boxes and rigid, top-down leadership. As William D. Eggers, executive director of Deloitte's Center for Government Insights, and Donald F. Kettl, public management scholar, show in this indispensable book, we need a government of bridgebuilders who collaborate with partners—inside and outside government—to get the job done. These leaders manage horizontally instead of vertically; they see their role as connectors; and they identify which players have the assets needed to solve the unprecedented problems at hand. Each chapter examines one of the ten core principles of bridgebuilding and features practical tips and dynamic cases of how effective leaders have put each bridgebuilding principle to work. The book also includes a special section that helps government leaders create a hundred-day bridgebuilding plan. Throughout, Eggers and Kettl tell fascinating and instructive stories about some of today's bridgebuilders—federal, state, and local government leaders who transcend boundaries, partner across sectors, and get stuff done. Trusted and effective government has never been more important than today. Bridgebuilders provides a new model that current government decision makers—as well as young leaders who aspire to public service—can learn from and apply right now to transform government and restore public trust.
