摘要:· As foundations seek to catalyze broad-based social change, there is a need for greater understanding of what social movements are, how they evolve, and how foundations can support them. · Movement building presents unique challenges to foundations. Because movements, by definition, must be driven by the people who are most affected, foundations cannot determine the goals and timetables of a movement. · The authors identify five core elements to movement building: organizing an authentic base; leadership; vision and ideas; alliances; and advocacy infrastructure. · A framework for evaluating movement building is proposed, which can help foundations identify measureable outcomes and track progress throughout a movement’s various stages.
