The membership of OC consisted of representatives of the participating organizations of ACC. OC received directives from and reported directly to ACC. It met twice a year, two to three weeks before the ACC session and immediately following it.
Committees Reporting through the OC:
- Joint United Nations Information Committee (JUNIC)
- Information Systems Coordination Committee (ISCC)
- Ad Hoc Inter-Agency Meeting on Security
The functions previously performed by OC are now carried out by a network of focal points (Sherpas) along with the High-level Committee on Programmes and the CEB Secretariat.
