Book excerpt: Exploring how cross-sector collaboration can solve seemingly intractable societal problems Many people tend to think of the public, non-profit and private sectors as being distinctive components of the economy and broader society—each with its own missions and problems to address. This book describes how the three sectors can work together toward common purposes, accomplishing much more than if they work alone. With the nation reeling from multiple challenges, more than ever the United States needs these sectors to collaborate to address what might seem to be intractable problems. Cross-sector collaborations and partnerships are more crucial than in the past as the country tries to recover from the economic, health, and broad social dislocations caused by the COVID-19 pandemic. At a time when trust in institutions, both public and private, is at an all-time low, cooperation among the sectors can be a confidence-inspiring approach to addressing public problems. This book reviews the state of cross-sector collaborations, identifies emerging practices, and offers a range of perspectives from experts in the field. Practitioners show how cooperation among sectors is relevant to their core missions. Scholars from a wide range of disciplines discuss both the broad and specific concepts that advance understanding of cross-sector collaboration. At a time when the United States must recover from and address new challenges, the book shows how cross-sector collaborations can help ensure a brighter future. Its core conclusions should be of particular interest to leaders in each of the broad sectors, as well as educators and students at both the undergraduate and graduate level.
