We at CCMU published The Rise of Collaboration: A Case Study Analysis of Colorado's Health Alliances. This report provides examples of local health alliances at three different stages along a collaboration spectrum and highlights keys to success and lessons learned. Looking across all the alliances, there are four core contributors to their success: Strong leadership: Alliances are guided by people in leadership roles at their institutions and were led in their formation by strong facilitators. Strong relationships: In addition to achieving programmatic goals, alliances are convened to build relationships among key players in the health system. Action-oriented: With or without dedicated staff, health alliances rely on project- or subject-specific task teams to fulfill the alliance's goals and work plans. Neutral convener: Alliances are an impartial convener in their communities. At CCMU, we're thrilled to be a part of sharing and developing best practices around Collective Impact and collaboration in communities across our state. We are continually impressed by the work of Colorado's health alliances, and hope their experiences can inform the work of other groups just getting started on their own collaborative efforts.
