Which structure is defined by direct, clear lines of authority from the top down, with no separation of staff and line?

• A. Line Organization
• B. Line-and-Staff Organization
• C. Functional Departmentalization
• D. Geographic Departmentalization

Answer: (A)

Direct, clear lines of authority from the top down with no separation of staff and line describe a line organization. In this structure, authority flows along a single, unbroken chain from the top leader to each subordinate, and every person reports to one supervisor. The line managers are responsible for both planning and execution within their units, and there isn’t a separate staff layer that provides specialized advice or support with its own authority. This arrangement makes accountability straightforward and decisions quick, since everything follows the direct chain of command.

Other structures change how authority or support is organized. A line-and-staff setup adds staff specialists who advise or support the line but don’t have direct command over line workers, creating a separation in the command structure. Functional departmentalization groups activities by function (such as marketing, finance, production) rather than by a direct command chain, and geographic departmentalization organizes by location.
