Agent utilization is the percentage of time that agents are occupied with handling customer interactions or after-call work. It is a measure of how efficiently agents are using their time. Schedule adherence is the degree to which agents stick to their planned work schedules. It is a measure of how well agents follow their assigned shifts, breaks, and lunches. Both metrics can be used to assess the success of a new workforce management system, as they indicate how well the system is optimizing agent productivity and availability.
