Abstract: A method and system for product measurement validation is provided. The method includes receiving a product sales file from a number of retail entities, the product sales file including records of universal product code (UPC) data and measured values of products. The method also includes grouping the records in each of the product sales files by product and supplier identifiers and determining a consistency value for each product. The consistency value is determined by comparing the measured value of the product to a validation value assigned to the product via the UPC, the validation value representing a target measurement for the product. The consistency value is further determined by graphing measurement values and identifying any deviance resulting from the comparing and analyzing results of the graphing by product identifier and supplier identifier to determine whether the measured values of a product provided by a supplier are consistent with the validation value.
