This document summarizes Katrina Huffman's presentation on measuring impact at the 2014 Nonprofit Empowerment Summit. It discusses Youth, I.N.C.'s venture philanthropy continuum model of working with partner organizations from seed funding to growth funding. It emphasizes the importance of having a clear theory of change, logic models, and evidence to prove an organization's impact. The document presents two sample organizations, Tonya and Toyin, and compares their processes, systems, budgets, and ability to scale and demonstrate impact. It acknowledges that measuring impact can help make sense of the complex realities ("mess") of measuring people and outcomes.
