Patent ID: 8761380

Claim:
A method comprising: at a first time applying, by a processor, a first Estimated Wait Time (“EWT”) algorithm to a first work item of a contact center to obtain a first EWT, wherein the first work item corresponds to a contact received in a waiting queue; at the first time applying, by the processor, a second EWT algorithm to the first work item of the contact center to obtain a second EWT; and determining, by the processor, a preferred EWT algorithm, wherein the preferred EWT algorithm is selected from one of the applied first and second EWT algorithms, and wherein determining the preferred EWT algorithm further comprises: determining an actual wait time for the first work item that corresponds to an actual amount of time that elapsed between the first time and a second time, wherein the second time corresponds to when the first work item is assigned to a resource; comparing the first EWT with the actual wait time to determine a first difference; comparing the second EWT with the actual wait time to determine a second difference; and selecting, by the processor, and as the preferred EWT algorithm, one of the applied first and second EWT algorithms based on rules, wherein the rules use at least one of the first and second difference.
