The Multilateral Organisation Performance Assessment Network (MOPAN) is a network of donor countries with a common interest in assessing the organisational effectiveness of multilateral organisations. MOPAN was established in 2002 in response to international fora on aid effectiveness and calls for greater donor harmonisation and coordination. Each year MOPAN carries out assessments of several multilateral organisations based on criteria agreed by MOPAN members. Its approach has evolved over the years, and since 2010 has been based on a survey of key stakeholders and a review of documents of multilateral organisations. MOPAN assessments provide a snapshot of four dimensions of organisational effectiveness (strategic management, operational management, relationship management, and knowledge management). MOPAN does not examine an organisation’s development results.
