The Chief Executives Board (CEB) furthers coordination and cooperation on a whole range of substantive and management issues facing United Nations system organizations. CEB brings together on a regular basis the executive heads of the organizations of the United Nations system, under the chairmanship of the Secretary General of the United Nations.

In addition to its regular reviews of contemporary political issues and major concerns facing the UN system, on the basis of recommendations from bodies reporting to it, CEB approves policy statements on behalf of the UN system as a whole.

CEB is the successor body to the Administrative Committee on Coordination (ACC). It furthers coordination and cooperation on a whole range of substantive and management issues facing UN system organizations. CEB is supported by three High Level Committees, HLCP, HLCM and UNDG. The division of responsibilities between the three bodies can be summarized as follows:
 
HLCP: Promotion of global policy coherence, including the development of common policy tools, including toolkits, in addition on its work on global policy and programme issues and global public goods.
 
HLCM: Harmonization of business practices across the system, including general management issues, thus ensuring overall managment coherence from global to country level.
 
UNDG: Promotion of coherent and effective oversight, provision of guidance and capacity building with country level partners, coordination of UN development operations at country level, addressing policy guidance issues related to country level operations, including the implementation of the TCPR resolutions, and support to the RC system.
