"First Come First-Served" method of appointment scheduling is typically implemented by operating during what?

• A. Open hours
• B. Fixed appointment blocks
• C. Evening only
• D. Appointment-only systems

Answer: (A)

First-come, first-served means patients are seen in the order they arrive, with no pre-set appointment times. To support that flow, clinics typically operate during open hours, where people can walk in at any time and be seen in sequence as they arrive. This setup naturally yields FCFS because there aren’t fixed time slots guiding who is seen next. Fixed appointment blocks require pre-scheduled times, which undermines FCFS by design. Appointment-only systems also rely on scheduled slots, not arrival order. Evening-only could be consistent with FCFS if there were open hours in the evening, but the key point is open hours in general—walk-in access that lets the next arriving patient be seen next.
