Most of the recent discussions in international development have been about promoting evidence-informed decisions by policymakers and program implementers from L&MICs. What has been less discussed is the practice and the decisions taken by international development institutions on the extent of using data and research to diagnose and address problems in their country programming. In this Evidence Dialogues webinar, we discussed how institutions can incentivize, put systems in place, and train people in using research and evidence to design the best possible interventions, policies and programs and to ensure continuous monitoring, evaluation, learning and adaptations so as always to strive to support the most cost-effective development programs.
