OSCAF is governed by the members it serves. It is open to all types of organisations and individuals (see separate membership section below). Its governance structure consists of Associated and Full Members, the General Assembly, the Board of Directors (BOD) and the Chief Executive Officer (CEO).

OSCAF is an open-membership organisation adopting different levels of membership that are outlined in the -> section below.

General Assembly
The General Assembly (GA) is a member council of the entire membership and is held on a regular basis at least once a year. It consists of all members and deals with organisational matters first. Organisational members designate one representative. The council operates on a one-vote-per-member basis. Members (or members' representatives) come from many types and sizes of organisation, bringing different perspectives to the Members Council. The general meeting elects the Board of Directors.

Specific proceedings at General Assemblies are described in detail in the Articles of Association according to Irish law, such as: participants, agenda, decision making and voting, quorum of members, chairman, elections, place of meeting, etc..

Board of Directors
The Board of Directors (BoD) including the CEO, the ultimate legal authority within the organisation, is composed of 3 representatives elected from OSCAF Members. The BoD charters Plenary Bodies and is responsible for the direction and fiscal health of the OSCAF. It represents the OSCAF to the public and to the member organisations. At the end of the Technology Adoption Process, a vote of the BoD changes the status of a document from submission to official OSCAF specification.

The Board of Directors (BoD) appoints the CEO. It meets at least once annually. The directors have overlapping periods of duty to ensure continuity. According to Irish law at least one of the directors has to be resident in Ireland.

CEO
The Chief Executive Officer (CEO) is responsible for the operating of the daily business, coordinates the work and activities of the OSCA Foundation, and provides the yearly budget plans. The CEO also presents and represents the OSCA Foundation to the outside world, and chairs the General Assembly. The CEO is contracted by the Board of Directors and is a member of the Board of Directors. If appropriate (e.g. increased capacity) the BoD may create an Executive Committee consisting of two or more executives.

Optionally, the Board of Directors may appoint and be supported by an Advisory Committee (AC), which reviews all important recommendations, suggestions for groups, changes to the process. Each member organisation has one seat in the Advisory Committee. The role is decision making and reviewing. The director may be part of the AC.
