Research and advocacy work designed to influence policy is a growing area of operation in the non-profit sector, among non-government organisations and more recently in some government departments concerned with aid and development. Assessment of the effectiveness of such work, both the immediate outcomes and the integration with broader organisational aims and goals has received little attention until recently. This paper draws from two areas, the emerging discussions about evaluation of advocacy programs, and the broader literature about organisational performance measurement. It seeks to outline a process for NGOs and others to assess the contribution advocacy and research work makes to their organisational goals and mission.
