Informed decision making requires timely and relevant evidence. This holds for national decision makers as well as development practitioners. Here at the World Bank, we have been working on creative solutions that lower the cost of project monitoring and create feedback loops. These feedback loops allow decision makers to assess the impact of their actions and to plan course corrections where needed. They also serve as incentive to act, since most decision makers wish to avoid the possibility of their inaction being exposed in future rounds of feedback and data collection. Feedback loops thus improve development outcomes through two pathways: by providing timely and actionable information and by functioning as an accountability mechanism. SWIFT and IBM are two examples of new tools that make this kind of regular feedback affordable.
