This volume is the last in a series of papers about systems approaches in complex environments, which includes the use of the collective impact model to address large-scale social problems, and the application of participant-driven MEL techniques across 17 networks of civil society organizations. It is based on the experiences of Root Change and Chemonics, two development partners working on a USAID civic engagement project in Nigeria (2013-2018), as well as hundreds of civil society organization partners. This is the final paper in the series and aims to highlight how the adaptation of participatory monitoring, evaluation, and learning techniques (e.g., most significant change, outcome mapping, and outcome harvesting) evolved and ultimately empowered cluster members.
