An important distinction in many organizations is between line authority and staff authority, reflecting whether managers work in line or staff departments in the organization’s structure. Line department performs tasks that reflects the organization’s primary goal and mission. In a software company, line departments make and sell the product. In an Internet-based company, line departments would be those that develop and manage online offerings and sales. Staff departments include all those that provide specialized skills in support of line departments. Staff departments have an advisory relationship with line departments and typically include marketing, labor relations, research, accounting, and human resources.

Line authority means that people in management positions have formal authority to direct and control immediate subordinates. Staff authority is narrower and includes the right to advise, recommend, and counsel in the staff specialists’ area of expertise. Staff authority is a communication relationship; staff specialists advise managers in technical areas. For example, the finance department of a manufacturing firm would have staff authority to coordinate with line departments about which accounting forms to use to facilitate equipment purchases and standardize payroll services.
