This paper in the IDIA Insights series focuses on various challenges and lessons learned of funders seeking to measure the impact of development innovations they support. It draws on the experience and learning of a wide range of bilateral, multilateral, philanthropic and civil society actors who came together in a Working Group on Measuring Impact facilitated by the International Development Innovation Alliance (IDIA). While it does not represent the formal strategy or approach of any one single agency in the Working Group or IDIA itself, it does reflect areas of overlapping interest and terminology that can be used as a point of reference for interested stakeholders in reflecting on, and enhancing, their own approaches to measuring the impact of development innovations.
Tools and approaches to measuring impact continue to emerge and evolve at a rapid pace. The insights con- tained herein will therefore benefit from regular review and iteration to accurately capture continuing advances in knowledge and practice. In its current form, this document provides a broad architecture of impact domains and indicator sets intended to help funders in measure and predict the outcomes of the innovations they support. The insights collected in this paper are also likely to be valuable in helping innovators themselves and other partner organizations develop their own impact measurement approaches, thereby acting as a potential catalyst for deeper and more productive partnerships.
