Chief of staff
identifies the leader of a complex organization, institution, or body of persons
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. 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). Organizations such as the Chief of Staff Association have created a global community of Chiefs and deliver executive education programmes.
Civilian
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. 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. 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; 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).

Why this record matters
A short description can identify a subject without explaining its stakes. For “Chief of staff”, the useful work is to connect “identifies the leader of a complex organization, institution, or body of persons” to the records capable of establishing context and consequence.
