DOD Business Transformation: Status of DOD's Actions on Previous Recommendations for the Defense Travel System

GAO has made 14 recommendations aimed at improving DODs management oversight and implementation of DTS and related travel policies to make DTS the standard departmentwide travel system. GAO considers 7 of the 14 recommendations closed and the remaining 7 recommendations as being open. The 7 closed recommendations pertained to premium-class travel, unused airline tickets, use of restricted airfare, proper testing of system interfaces, and streamlining of certain travel processes, such as the process for approving travel voucher expenses. GAOs analysis of the 7 closed recommendations found that the actions taken by the department responded to the intent of the recommendations. Of the 7 open recommendations, 3 related to the adequacy of DTSs requirements management and system testing, 3 to DTS underutilization, and 1 to developing an approach that will permit the use of automated methods to reduce the need for hard copy receipts to substantiate travel expenses. In the area of requirements management and testing, GAO found that while DTSs requirements management and testing process has improved, problems still persist. The problems were generally related to missing documentation, the limited scope of requirements testing performed, or both. In the area of DTS utilization, GAO found that the department still does not have in place the metrics to determine the number of manual travel vouchers that should have been processed through DTS.
