How does a line-and-staff organization combine direct authority with specialized support?

"The line organization is designed with direct, clear lines of authority and communication flowing from the top managers downward. Managers have direct control over all activities, including administrative duties. An organization chart for this type of structure would show that all positions in the firm are directly connected via an imaginary line extending from the highest position in the organization to the lowest (where production of goods and services takes place). This structure, with its simple design and broad managerial control, is often well-suited to small, entrepreneurial firms. As an organization grows and becomes more complex, the line organization can be enhanced by adding staff positions to the design. Staff positions provide specialized advisory and support services to line managers in the line-and-staff organization, shown in Exhibit 7.6. In daily operations, individuals in line positions are directly involved in the processes used to create goods and services. Individuals in staff positions provide the administrative and support services that line employees need to achieve the firm’s goals. Line positions in organizations are typically in areas such as production, marketing, and finance. Staff positions are found in areas such as legal counseling, managerial consulting, public relations, and human resource management."
