The Open Government Partnership (OGP), donors and multilaterals, and social accountability practitioners across the world are among various constituencies attempting to harness and actualise emerging insights about the nature of successful governance reform. But each of these groups faces challenges as they do so. An increasingly compelling body of evidence suggests that governance reform is inherently political and complex, and that reform efforts are most likely to be successful when: - local stakeholders are at the forefront of defining governance challenges, developing and implementing solutions, and pursuing sustainable change; and - those stakeholders have the flexibility to learn and adapt as they go, especially when working in complex political contexts. This brief reviews the evidence from Learning to Make All Voices Count (L-MAVC), a programme funded by Making All Voices Count, and implemented in collaboration with Global Integrity. L-MAVC intended to support six Making All Voices Count grantees, working in five countries, in co-creating and applying a participatory, learning-centred, and adaptive approach to strengthening citizen engagement in governance processes in their contexts, including with respect to the Open Government Partnership (OGP).
