ATLAS elects its leadership. Candidates for a particular leadership position (such as Project Leader for a particular system) are proposed by the groups working on that system. Candidates for Spokesperson, and Collaboration Board (CB) Chair are proposed by the membership of the whole collaboration. The leadership is then elected, and their proposed "management teams" have to be endorsed. The "electing bodies" are the institutions relevant to the particular position, namely the whole collaboration for the CB Chair or Spokesperson, or the institutions participating in a given detector system in the case of a project leader for that system.
