We recommend that the GSA Administrator, FAS Commissioner, and Associate Administrator of the Office of Government-wide Policy address the problems with the TDR data and usage as described in this report within 1 year of report issuance. To do so, GSA should, at a minimum: conduct a comprehensive assessment of all TDR data; verify the accuracy and completeness of all TDR data; implement a verification process to ensure that TDR data is accurate and complete when it is submitted by MAS contractors; require the contractors that are not submitting complete and accurate data to correct their data or suspend their contract; make the data accessible to all MAS contracting personnel; and develop a methodology for pricing using TDR data that will ensure that customer agencies meet the Competition in Contracting Act for orders placed through MAS contracts.
