The term agencies, funds and programmes is often used as a shorthand for the operational agencies within the system other than the Secretariat. In addition to the funds and programmes and the specialized agencies, the colloquial use of this term also covers other entities such as UNHCR and related organizations such as IOM.

The common system is often used as a shorthand for the organizations within the United Nations system that adhere to the common system of salaries, benefits and allowances.

United Nations
The United Nations consists of the six Main Organs defined in the Charter of the United Nations and their subsidiary organs, which can include committees, operational agencies or organs with characteristics of both. For the purposes of this article, only the operational agencies are listed.

Main bodies

 * The General Assembly

The terms of appointment of the Secretary-General are outlined in General Assembly 11 (I), and additional considerations are contained in the annexes to resolution 51/241 and 60/286.

Funds and programmes
The funds and programmes are subsidiary organs of the United Nations, under Article 7.2 of the Charter, and do not have separate juridical personality from the United Nations even if they are separately administered.
 * United Nations Development Programme (UNDP)
 * UNDP was established with the adoption of General Assembly resolution 2029 (XX) through the merger of the United Nations Special Fund and the Expanded Programme of Technical Assistance. UNDP is led by an Administrator (formerly the Managing Director of the Special Fund), appointed by the Secretary-General and subject to confirmation by the General Assembly.
 * UNDP, UNFPA and UNOPS are overseen by a joint Executive Board, which replaced the earlier UNDP Governing Council with the adoption of General Assembly resolution 48/162.

Specialized agencies
Specialized agencies are autonomous organizations whose work is coordinated through ECOSOC at the intergovernmental level and the Chief Executives Board (CEB) at the inter-Secretariat level, in line with articles 57 and 63 of the Charter.
