A method is provided. The method comprises associating a first pairing strategy to a first plurality of contacts during a first period of time, associating a second pairing strategy to a second plurality of contacts during a second period of time, associating a third pairing strategy to a third plurality of contacts during a third period of time, associating the first pairing strategy to a fourth plurality of contacts during a fourth period of time, associating the second pairing strategy to a fifth plurality of contacts during a fifth period of time, associating to a sixth plurality of contacts during a sixth period of time, determining a first performance measurement based on outcomes of the first, second, fourth, and fifth pluralities of contacts, determining a second performance measurement based on outcomes of the third and sixth pluralities of contacts, and outputting data that enables a comparison of the first and second performance measurements.
