“For decades, individuals and organizations have been trying to solve our greatest challenges through siloed solutions. More recently, we have seen significant growth in the use and diversity of models of cross sector collaboration. … Some of these efforts are able to create meaningful collaborations and drive measurable impact, while others end up doing more co-blab-orating, than collaborating. So what differentiates high-impact collaborations and what roles can volunteers play in supporting their success? Through independent research and observation, the Presidio Institute has identified cross sector leadership skills that effective leaders and collaborations use in their practice. Because cross sector collaborations operate outside of traditional methods of authority and accountability, a key component of this work is building teams. In this session, we will explore the importance of developing trust, managing power dynamics and conflict, and fostering an innovative culture to successfully build alliances to solve problems and achieve shared goals.”
