The present report provides an overview of inter-agency cooperation within the framework of the United Nations System Chief Executives Board for Coordination (CEB) in 2017. The report highlights the key activities of the Chief Executives Board in fostering a coherent approach to policy, management and operational matters so as to enhance United Nations system-wide coordination in support of intergovernmental mandates. In 2017, CEB strengthened the collective capacities of United Nations system entities to support Member States in implementing the 2030 Agenda for Sustainable Development through joint efforts in the area of risk and resilience and a common approach on the part of the leadership of the United Nations system. Through its High-level Committee on Programmes, the Board emphasized the ever-advancing contribution of scientific and technological innovations to sustainable development. Through its High-level Committee on Management, it focused on administrative and management issues with system-wide implications in the areas of human resources and information, finance and budget, information and communications technologies and procurement. Seeking to increase the effectiveness and impact of operational activities of the United Nations system, CEB, through the United Nations Development Group, reviewed its operational support role and continued to mainstream and accelerate the implementation of the Sustainable Development Goals and to support the implementation of the quadrennial comprehensive policy review of operational activities for development of the United Nations system. The report also highlights coordination activities between CEB and other jointly financed bodies.
