How to implement policies with impact?

Abstract

How can policies generate impact? Many governments know how to pass laws but struggle to execute those laws. They successfully legislate to build schools, but children still aren’t learning. Why? What are the capabilities governments need to go from successfully delivering policy products to actually fostering real policy impact? This is the question addressed here. Using data from multiple case studies, we offer a list of key capabilities for yielding policies with impact. Based on these capabilities, policymakers can use the Problem-Driven Iterative Adaptation (PDIA) toolkit to develop policy responses with impact.
