Collective Impact is well-known in the philanthropic and nonprofit community. But what about engaging more diverse stakeholders in your efforts? This session explores a case study of collective impact in community health. With representation from the funder, local government, nonprofit, and health sectors, we provide detailed information about our partnership’s dynamic and evolving structure – including components like our annual summit, shared data dashboard, peer-learning events, and more – that have facilitated effective collaboration. Presenters will dive deep into three real-life scenarios that posed challenges to our collective work and how we charted our path forward. These will include: 1) structuring equity-focused, trust-based partnerships for collective impact; 2) fostering collaboration among "technical experts" like medical professionals, who may be unfamiliar with collective impact approaches; and 3) overcoming obstacles in creating shared metrics and supporting diverse partners in sensitive data sharing.
