Numerous organizations advocate the need to ‘bridge research and policy’. Philanthropic foundations, national social science funding regimes and international organizations have sought to improve knowledge utilization. Similarly, research consumers such as NGOs and government departments complain of research irrelevance for policy purposes. The concern of this article is with ‘evidence informed policy’ within the field of international development in which the Overseas Development Institute (ODI), a London-based think tank, forms the case study. Most think tanks are driven by the need to influence immediate political agendas but ODI has also developed organizational strategies of policy entrepreneurship that extend to longer term influence through creating human capital, building networks and engaging policy communities.
