A call-management method and system for distributing calls to agents, wherein each agent has a profile, e.g., defining agent skills, efficiency, etc. The call center management system implements an algorithm for selecting an agent to receive a call to optimize caller utility, call center efficiency, and agent training. Therefore, the algorithm does not seek to necessarily route a call to the agent having the skill set most suited to the call; rather, the call may be routed to an agent who needs experience in the area of the call, and thus serves as a training exercise. Skilled agents may be made available to shadow the training agent when available.
