The MSI Evaluation Tool and Evaluation Methodology provide a framework to comprehensively and objectively evaluate the effectiveness of an MSI’s institutional design, structure, and operational procedures. They draw together current research and practical understandings about MSI structures and processes, recognizing that MSI design features — such as good governance and robust accountability mechanisms — influence an initiative’s effectiveness and potential to achieve positive impacts. By examining an MSI’s institutional framework, the Tool enables individuals, organizations, and MSIs themselves to better understand and evaluate the capacity of an MSI to affect change.
