Three evolving approaches to evaluation in social enterprise could change its use in a significant way. In this audio lecture, Hallie Preskill, FSG managing director, opens the 2013 Next Generation Evaluation conference with examples of how leading social sector organizations are thinking about and implementing evaluation. Preskill discusses three new approaches to evaluation: developmental evaluation, shared measurement, and big data, providing context from multiple perspectives. She describes six characteristics that exemplify how social organizations are thinking about evaluation in relation to the new trends. In this podcast, Preskill explains how evaluation practice needs to evolve along with other developments in process and infrastructure to keep up with the needs of social enterprise. https://ssir.org/podcasts/entry/optimized_social_responsibility_through_evaluation
