Chief of staff (or head of staff) is a leadership title with different meanings in civilian and military organizations. In civilian government organizations and businesses, a chief of staff is a primary aide-de-camp to an important individual, such as a president or leader of a large organization.[1][2] In military organizations, a chief of staff is the leader of a complex organization, such as one of a country's armed forces, while the role that coordinates supporting staff for a senior military officer may be titled a principal staff officer (PSO).

In civilian organizations, 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 a chief of staff acts 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;[3] 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; and as a confidant without an organizational agenda. An organization may also hire an associate chief of staff (ACoS), a senior operational role that serves as a partner to the chief of staff (CoS).

In France, a distinction is made between a politician's directeur de cabinet and chef de cabinet. The directeur de cabinet is tasked with organising the work of the staff and is authorised to make certain decisions or speak on behalf of the politician. It is thus the more political role. The chef de cabinet is under the authority of the directeur de cabinet and is tasked with organising the politician's agenda.[4]

At the Élysée, a third function exists: the Secrétaire général de la présidence de la République (Secretary-General of the Presidency of the Republic). The officeholder is the de facto chief of staff to the President of France, above the directeur de cabinet and chef de cabinet. The secretary-general is the president's closest advisor, coordinating with the government and taking part in the weekly Council of Ministers.[5][6]
