Abstract

In a skills-based ACD, an available agent is reserved and assigned to handle calls needing a "rare" skill of the agent and is prevented from handling calls needing a "common" skill of the agent even if calls needing the common skill are waiting to be handled, if not reserving the agent for the calls needing the rare skill would deprive those calls of the last available agent, even if no calls needing the rare skill are available for handling. The agent is reserved only if target performance criteria, such as average speed of answer, for handling the calls needing the common skill are being met. In case of more than one agent being available to handle calls that need the rare skills, one of these agents is selected and reserved and the other agents are freed to serve calls needing "common" skills.

Claims

1. A method of assigning a call handler to handle a call, comprising the steps of:

in response to a call handler having both a rare skill and a different common skill becoming available to handle a call, determining whether assigning the call handler to handle a call needing the common skill would deprive calls needing the rare skill of an only available call handler having the rare skill; and

in response to determining that the assignment would deprive the calls needing the rare skill,

assigning the call handler to handle a call needing the rare skill even when no call needing the rare skill is available for handling by the call handler, and

forbearing from assigning the call handler to handle calls needing the common skill even when a call needing the common skill is available for handling by the call handler.

2. The method of claim 1 wherein:

the step of determining comprises the step of

determining whether a service objective is being met for the calls needing the common skill; and

the step of forbearing from assigning is further conditioned upon determining that the service objective is being met.

3. The method of claim 1 further comprising the steps of:

in response to determining that the assignment would not deprive the calls needing the rare skill,

selecting one of the available call handlers having the rare skill,

assigning the selected one call handler to handle a call needing the rare skill even when no call needing the rare skill is available for handling by the selected one call handler,

forbearing from assigning the selected one call handler to handle calls needing the common skill even when a call needing the common skill is available for handling by the call handler, and

assigning all non-selected call handlers having the rare skill to handle other calls.

4. The method of claim 1 wherein:

the step of determining comprises the steps of;

determining whether a call needing the rare skill is available for handling,

determining whether another call handler having the rare skill is available for handling the call needing the rare skill,

determining whether a call needing the common skill is available for handling, and

determining whether a service objective is being met for the calls needing the common skill; and

the step of assigning is conditioned upon determining that a call needing the rare skill is available, that another call handler having the rare skill is not available, that a call needing the common skill is available, and that the service objective is being met.

8. An apparatus that performs the method of claims 1 or 2 or 3 or 4 or 5 or 6 or 7.

9. A computer-readable medium containing software which, when executed in a computer, causes the computer to perform the steps of claims 1 or 2 or 3 or 4 or 5 or 6 or 7.

5. A method of assigning a call handler to handle a call in an environment that comprises a plurality of call queues each corresponding to a different skill and for identifying calls waiting to be handled by a call handler having the corresponding skill, comprising the steps of:

in response to a call handler, who has both one or more rare skills and different one or more common skills, becoming available to handle a call, determining whether all non-empty call queues that correspond to the agent'"'"'s skills correspond to the agent'"'"'s common skills, and determining whether service objectives are being met for calls needing skills corresponding to each of the non-empty call queues that correspond to the agent'"'"'s common skills; and

in response to a determination that all non-empty call queues that correspond to the agent'"'"'s skills correspond to the agent'"'"'s common skills and that service objectives are being met for calls needing skills corresponding to each of the non-empty call queues that correspond to the agent'"'"'s common skills, if assigning the call handler to handle calls from the call queues corresponding to the call handler'"'"'s common skills would deprive a rare skill of an only available handler, assigning the call handler to handle calls from the call queues corresponding to the call handler'"'"'s rare skills, and forbearing from assigning the call handler to handle calls from the call queues corresponding to the agent'"'"'s common skills.

6. The method of claim 5 further comprising the step of:

in response to said determination, further assigning the call handler to handle calls from a call queue corresponding to a normal skill of the agent, the normal skill being a skill other than the rare skills and the common skills.

7. The method of claim 5 wherein:

the steps of assigning and forbearing from assigning comprise the steps of;

determining whether another call handler is available to handle a call from each of the call queues corresponding to the call handler'"'"'s rare skills;

in response to determining that another call handler is not available to handle a call from each of the call queues corresponding to the call handler'"'"'s rare skills, assigning the call handler to handle calls from the call queues corresponding to the call handler'"'"'s rare skills, and forbearing from assigning the call handler to handle calls from the call queues corresponding to the agent'"'"'s common skills; and

in response to determining that another call handler is available to handle a call from each of the call queues corresponding to the call handler'"'"'s rare skills,

selecting one of the call handler and the other call handler,

assigning the selected call handler to handle calls from the call queues corresponding to the selected call handler'"'"'s rare skills,

forbearing trom assigning the selected call handler to handle calls from the call queues corresponding to the selected call handler'"'"'s common skills, and

assigning the non-selected call handler to handle calls from the call queues corresponding to any of the non-selected call handler'"'"'s skills.

10. An apparatus for assigning a call handler to handle a call, comprising:

an effector, responsive to a call handler having both a rare skill and a different common skill becoming available to handle a call, of determining whether assigning the call handler to handle a call needing the common skill would deprive calls needing the rare skill of an only available call handler having the rare skill; and

an effector, responsive to a determination that the assignment would deprive the calls needing the rare skill, of assigning the call handler to handle a call needing the rare skill even when no call needing the rare skill is available for handling by the call handler, and of forbearing from assigning the call handler to handle calls needing the common skill even when a call needing the common skill is available for handling by the call handler.
