I put this chart together a few years ago to show external organizations (and our own volunteers!) how we’re organized. The Professional Activities Board is highlighted because I was working to establish cooperative relationships with FEAPO, the EABOK Consortium, and more lately, The Open Group.
The Computer Society is a volunteer-led non-profit organization that is headed by an elected volunteer Board of Governors The officers are generally referred to as the ExCom: the President, First Vice President, Second Vice President, and Secretary are elected to one year terms; each Program Board is chaired by a VP who is appointed by the President. Typically, the First and Second VPs are also appointed to chair Program Boards.
