As part of the Leadership for a New Era (LNE) initiative, the Leadership Learning Community has partnered with thought leaders in the network development and leadership development fields to develop the cutting-edge report Leadership and Networks: New Ways of Developing Leadership in a Highly Connected World. This publication is funded by the Annie E. Casey Foundation and the David and Lucile Packard Foundation. This report is written for those who run and fund leadership programs that develop and support leadership for social change. It shares many examples of how leaders using network strategies are increasing the impact of social change work, such as the Barr Fellowship Network and MomsRising.org. Our goal is to inspire and help hundreds of leadership programs to question their assumptions about the traditional leadership models and retool their approaches in ways that will enable them to better prepare those in leadership with the mindset and skills they will need to more fully leverage network strategies. Specifically, the report addresses the following questions: Why do network strategies deserve our attention? Why do we need a new leadership mindset? What are the core principles of leading with a network mindset? What leadership development strategies support a network mindset and skills?
