Furthermore, the international organizations such as the I.M.F. and the World Bank have independent evaluation functions. The various funds, programmes, and agencies of the United Nations has a mix of independent, semi-independent and self-evaluation functions, which have organized themselves as a system-wide UN Evaluation Group (UNEG), that works together to strengthen the function, and to establish UN norms and standards for evaluation. There is also an evaluation group within the OECD-DAC, which endeavors to improve development evaluation standards. The independent evaluation units of the major multinational development banks (MDBs) have also created the Evaluation Cooperation Group to strengthen the use of evaluation for greater MDB effectiveness and accountability, share lessons from MDB evaluations, and promote evaluation harmonization and collaboration.
