A department or unit that delivers services directly to external customers is best described as which function?

• A. Administrative Function
• B. Line Function
• C. Support Function
• D. Market Function

Answer: (B)

Line functions are the parts of an organization that directly produce the core service and interact with customers to deliver it. In a fire department, the units that respond to emergencies, fight fires, and provide EMS are on the front line and directly serve the public, so their work is line function work. Administrative functions handle overall management, policy, and clerical tasks and do not directly deliver services to external customers. Support functions provide specialized services to line units (like planning, logistics, or training) but still support internal operations rather than the external service delivery themselves. Market functions focus on outward-facing activities related to attracting or servicing customers, which isn’t the typical framework used to describe direct public service delivery in this context. So the department that delivers services directly to external customers fits the line function.
