Change is hard, but it is made easier when you understand the rules of the game. Whether you call it collective impact, system change or a movement, it requires constructing a strategic framework built upon research, convening a diverse group of stakeholders, developing ground rules for managing relationships and shared decision-making, and generating ongoing, meaningful value for each stakeholder. Social Impact Architects bridges disciplines and uses a combination of concepts from business (systems thinking, competition), public policy (coalition building, collaboration), and public health and education sectors (socio-ecologic model, upstream strategies) to co-create systems focused on large-scale impact.
