The title chief of staff (or head of staff) identifies the leader of a complex organization such as the armed forces, a government institution, or body of persons and it also may identify a principal staff officer (PSO), who is the coordinator of the supporting staff or a primary aide-de-camp to an important individual, such as a president, or a senior military officer, or leader of a large organization. [1] [2]
In general, a chief of staff provides a buffer between a chief executive and that executive's direct-reporting team. The chief of staff generally works behind the scenes to solve problems, mediate disputes, and deal with issues before they are brought to the chief executive. [1] Often chiefs of staff act as a confidant and advisor to the chief executive, acting as a sounding board for ideas. Ultimately the actual duties depend on the position and the people involved. [1] In an organization, the chief of staff may play a role that is metaphorically akin to an “air traffic controller for the leader and the senior team; as an integrator connecting work streams that would otherwise remain siloed; as a communicator linking the leadership team and the broader organization; as an honest broker and truth teller when the leader needs a wide-ranging view without turf considerations; and as a confidant without an organizational agenda.” [3]
In general, the positions listed below are not "chiefs of staff" as defined at the top of this page; they are the heads of the various forces/commands and tend to have subordinates that fulfill the "chief of staff" roles.[ citation needed ]
