"While there are multiple options for types of shared measurement systems... comparative performance systems offer an appropriate balance between usefulness and resource requirements. Comparative performance systems require all participants within a field (or community) to report on the same measures, using identical definitions and methodologies. As a result, users can compare the performance of different organizations and collect reliable field-wide data. Organizations can learn from each other’s performance, funders can make more informed choices, and the field as a whole, can more accurately document its influence and impact." (Mahmud)
