Abstract: A computer system and method for product testing, analysis and scoring wherein the method includes defining at least one critical to quality (CTQ) parameter for product performance, defining a product test plan to verify product performance against one or more CTQ parameters, conducting and monitoring product testing, determining relative index performance scores, constructing a scorecard for products tested, and optionally modifying the product scorecard. The system and method is useful for clients (i.e. store retailers or merchants), product vendors (i.e. product manufacturers or distributors of products), testing laboratories, customers (i.e. direct consumers of the products), and product performance intermediaries (i.e. testing coordinators and testing data analysts). This system and method allows these parties to interact, exchange information, and display information in tabular and graphical formats for determining how similar products perform relative to each other.
