Computerized systems and methods compute performance metrics for a sourcing department of a firm that measure the value-added from sourcing-related activities. Evaluation of the firm's sourcing department with the metrics should drive behaviors that optimize performance across the firm's entire sourcing portfolio. The new performance metrics include several metrics that isolate the impact of price changes and quantity changes on the overall run-rate of sourcing contracts, and several that measure of the attribution of run-rate impacts to both the sourcing department and the relevant business units. Other new metrics measure the changes in run-rate that are expected from and uncorrelated to, respectively, changes in market prices. The performance metrics can be aggregated across an expense category (or categories) and/or vendor (or vendors) to enhance expense management analytics.
