A well-managed social enterprise can translate idealism into action. It can help create a world that is more sustainable, more compassionate, and more just. This course will explore the distinctive aspects of launching, leading, and growing an enterprise -- nonprofit or for-profit -- whose primary goal is social impact. We will study mission, strategy, cause marketing, social entrepreneurship, and scaling. We will learn that success for social enterprise is driven less by a compelling story or a charismatic advocate than by diligent management and insightful leadership. The course will use a variety of lively in-class learning activities and assignments, including debates, role plays, case studies, site visits, and guest experts. All students will conduct a research project on a social enterprise of their choice, culminating in a paper and presentation.
