Since auto reserve agents are unavailable in other skills, use auto reserve agents only in skills for which achievement of service level targets is critical. The addition of even a single auto reserve agent can have a significant impact on the service level. Therefore, initially set the number of auto reserve agents on the Hunt Group screen to 0 or 1, observe the impact on the service level, and gradually increase the number of auto reserve agents by increments of one until you achieve the service level target.
