Double booking occurs when two or more customers or resources are booked at the same time. Appointment scheduling systems are normally set up to “block” slots that are already booked. This ensures that no more than a single customer is booked at a time. In some situations, for example with medical booking systems, double-booking may be allowed. For example, an urgent request for a same-day appointment may be double-booked. Another option is to allow multiple bookings per time slot, with the understanding that staff may be reallocated if more than one appointment is made.
