The article discusses the process of social innovation, emphasizing its historical evolution and current trends. It highlights that many aspects of modern social life, such as public transportation, national health services, and women's suffrage, were once considered radical innovations. The pace of social innovation is expected to accelerate in the coming century, driven by increased funding for NGOs and civil society. The article defines social innovation as activities and services aimed at meeting social needs, distinct from business innovation, which is primarily profit-driven. It outlines the stages of social innovation: idea generation, prototyping and piloting, scaling up, and continuous learning and adaptation. The process is influenced by various factors, including individual leaders, broader movements, and the environment. The article also addresses the challenges and failures of social innovation, noting that it often requires more than just individual effort and can be hindered by monopolistic power structures and lack of support from governments. Finally, it calls for more systematic approaches and research to support social innovation, suggesting the use of "innovation accelerators" and deliberately designed spaces in public services to foster experimentation and learning.The article discusses the process of social innovation, emphasizing its historical evolution and current trends.
