The CCSDS Management Council (CMC) is the executive management oversight group of the organization. The CMC is populated by Principal Delegates who are independently supported by each of the Members (one per agency). These Members may select the CMC chairman on a rotating basis. (Note: in practical terms, the rotation is infrequently activated.) The CMC is responsible for staying technically and politically informed about important long-term issues in the field of international space mission cross support and for keeping an eye on the "big picture" of the CCSDS program of work. It therefore focuses on long-range planning and coordination among the various CCSDS discipline-oriented domains, on making sure that adequate resources exist to do work, and that customer requirements are satisfied in a timely manner.
