The article "Rediscovering Social Innovation" by James A. Phills Jr., Kriss Deiglmeier, and Dale T. Miller explores the concept of social innovation as a novel solution to social problems that is more effective, efficient, sustainable, or just than existing solutions, with value primarily benefiting society as a whole. The authors argue that social innovation is a broader and more accurate framework than terms like social entrepreneurship or social enterprise, which often focus on individuals or organizations. They emphasize the importance of cross-sector collaboration, where ideas, values, roles, and resources flow freely between the public, private, and nonprofit sectors to drive social change. The article highlights examples such as microfinance and fair trade, which demonstrate how social innovation can create lasting impact. It also discusses the limitations of social entrepreneurship and social enterprise, which tend to exclude public and for-profit sectors. The authors stress the need for a clear, consistent definition of social innovation to guide research and practice. They conclude that social innovation is essential for addressing complex social problems and that cross-sector dynamics—exchanging ideas, shifting roles, and integrating private and public resources—are key to achieving this. The article calls for dismantling sectoral barriers to foster new solutions and emphasizes the role of collaboration in creating sustainable social value.The article "Rediscovering Social Innovation" by James A.
