Presentation: Andy Rowe, ARCeconomics. Moderation: Juha I Uitto, GEF Independent Evaluation Office. This video is the first part of the GEF IEO webinar on Rapid Impact Evaluation with Andy Rowe. RIE offers the potential to evaluate impacts in both ex ante and ex post settings providing utility for developmental and formative evaluation as well as summative settings. RIE triangulates judgments of three separate groups of experts to assess the incremental change in effects attributable to the intervention. Two methodological innovations are central to the method; the scenario-based counterfactual and a simplified approach to measuring change. In evaluations to date RIE has required less than two months, costs about 25,000 USD, and does not intrude on design or implementation of the intervention.
