The Multilateral Organisation Performance Assessment Network (MOPAN) was launched in 2002 as a network of 20 countries for monitoring the performance of mulitlateral development organisations at the country level. All members have a common interest in knowing more about the effectiveness of multilateral organisations, through joint assessments of these organisations, exchange of information and expertise in monitoring and evaluation. The Network’s assessments identify strengths and areas for improvement in the multilateral organisations. Findings are used for discussions with the organisations and with their partners, and as ways to further build the organisations’ capacity to be effective. Network members also use assessment findings as a source of input for strategic decision-making about their ways of engaging with the organisations, and as an information source when undertaking individual reviews.
