As grantmakers continue to explore ways of increasing the effectiveness and impact of nonprofits, we need to think differently about leadership and investments in individuals. There is a growing recognition that to achieve large scale change, we need to unleash collective leadership capacity within groups, organizations and communities; leverage networks using collaborative technologies; and support individuals and organizations working across differences to develop shared purpose, vision and coordinated action. To understand what is needed to achieve this scale of collaborative action, the Leadership Learning Community has joined forces with key innovators in the field to explore the topic of "Collective Leadership" as part of Leadership for a New Era – a collaborative research initiative focused on promoting leadership that is more inclusive, networked and collective. During this session, some of these innovators will present practical case studies and provide insights on models and tools for effectively supporting and evaluating the impact of collective leadership.
