Ask a passerby to name an innovative organization and a familiar list soon appears: Apple, 3M, Google,  or eBay. If you probe harder, they might even name one or two innovative organizations in the public sector, such as the U.S. Department of Defense’s Defense Advanced Research Projects Agency, which some credit as the inventor of the Internet. Rarely will anyone name an organization that is innovating to tackle social issues. Innovation is just as important in the social sector, where we need solutions to pressing problems such as obesity, homelessness, drug dependency, crime, and the education and health of our most vulnerable people. Tackling each of these issues is essential for the future success of the nation.
