In preparation of General Assembly resolution 67/226 on the quadrennial comprehensive policy review of United Nations operational activities for development, the United Nations Development Group worked in close collaboration with the Department of Economic and Social Affairs of the Secretariat to ensure that the deliberations of Member States were thoroughly informed by solid evidence and the collective advice of the United Nations development system. To this effect, the Group supported the gathering of evidence of global progress in the implementation of General Assembly resolution 62/208 at the country level, collectively informed the analytical preparations of the reports of the Secretary-General (A/67/93-E/2012/79 and A/67/320-E/2012/89), and provided technical advice upon request by Member States on the functioning of the resident coordinator system.
