In response to these changes and the need for the UN development system to be optimally geared to deliver on the next generation of sustainable development goals, a discussion is taking place, initiated by the UN system and member states, on how to make the UN more ‘fit for purpose’ to support delivery of the post-2015 agenda. This represents an opportunity for the UN, member states and other stakeholders to assess and reposition the UN development system vis-a-vis global development challenges and the new universal agenda that will be put in place to deal with them.
