Substantive inter-agency work is carried out by the CEB's three pillars: the High Level Committee for Programmes (HLCP), the High Level Committee for Management (HLCM) and the United Nations Development Group (UNDG). These bodies meet twice a year prior to CEB meetings, in order to ensure that their work feeds into CEB discussions. These pillars provide direction and guidance to substantive networks, working groups and task forces in each area under their responsibility. Agendas focus on harmonising efforts between organizations, but new and emerging issues that require policy coherence are also addressed, such as the global financial and economic crisis and climate change. 

High-Level Committee on Programmes (HLCP)

The High-Level Committee on Programmes promotes policy coherence and system-wide cooperation, coordination and knowledge sharing in strategic programme areas. Through its inter-agency mechanisms (UN-Water, UN-Oceans, UN-Energy and the HLCP Working Group on Climate Change) HLCP increases coherence in addressing urgent development challenges.

High-Level Committee on Management (HLCM)

The High-Level Committee on Management identifies and analyzes administrative management reforms with the aim of improving efficiency and simplifying business practices. The Committee is comprised of senior administrative managers from the member organizations of the United Nations system who meet twice a year. It is supported by networks in Finance and Budget, Human Resources, Procurement and ICT.

United Nations Development Group (UNDG)

The UNDG is responsible for coordinating operational activities at the country level. It derives many of its mandates from the Comprehensive Policy Review of operational activities for development of the United Nations system, a General Assembly resolution that serves as an important instrument for the monitoring and the assessment of UN development operations. UNDG maintains its own website.
