1. A method for handling contacts and agents in a contact center system comprising: applying, by at least one computer processor communicatively coupled to and configured to operate in the contact center system, a first matching strategy for matching a first contact with a first agent for connection in the contact center system; applying, by the at least one computer processor, a second matching strategy for matching a second contact with a second agent for connection in the contact center system, wherein the second matching strategy is different from the first matching strategy; establishing, by the at least one computer processor, in a telecommunications switch of the contact center system, communication channels between communication equipment of the first and second contacts and communication equipment of the first and second agents according to the matchings resulting from the applications of the first and second matching strategies; determining, by the at least one computer processor, a first outcome of an interaction between the first contact and the first agent using the first matching strategy and a second outcome of an interaction between the second contact and the second agent using the second matching strategy: generating, by the at least one computer processor, a first indicator of the first matching strategy; storing, by the at least one computer processor, the first indicator in association with the first outcome in an electronic database communicatively coupled to the contact center system; generating, by the at least one computer processor, a second indicator of the second matching strategy; storing, by the at least one computer processor, the second indicator in association with the second outcome in the electronic database communicatively coupled to the contact center system; and comparing, by the at least one computer processor, the first outcome based upon it association with the first indicator and the second outcome based upon its association with the second indicator to determine a first amount of performance gain for the contact center system attributable to the first matching strategy.
