In this lesson from Yale's Creating Change through Social Entrepreneurship course, students learn two frameworks for evaluating a social enterprise concept: the AAAQ checklist and the Theory of Change model. The lecture explains how these tools help strengthen an early stage idea, surface hidden assumptions, and clarify the causal path from an intervention to its intended social impact before significant resources are committed. As an evaluative step early in the venture design process, the lesson gives students a structured way to pressure test their ideas before moving on to later course material on differentiation, revenue models, and financing.
