This testimony is based on previously issued GAO reports and testimonies that highlighted challenges confronted by DOD in the implementation of DTS. More specifically, today's testimony focuses on prior GAO reporting concerning (1) the lack of quantitative metrics to measure the extent to which DTS is actually being used, (2) weaknesses with DTS's requirements management and system testing, and (3) two key assumptions related to the estimated cost savings in the September 2003 DTS economic analysis were not reasonable. Today's testimony also highlights some actions that DOD could explore to help streamline its administrative travel processes such as using a commercial database to identify unused airline tickets. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-08-649T/html/GAOREPORTS-GAO-08-649T.htm https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-08-649T/pdf/GAOREPORTS-GAO-08-649T.pdf GAO-08-649T https://www.govinfo.gov/app/details/GAOREPORTS-GAO-08-649T Testimony GAO-08-649T; Defense Travel System: Overview of Prior Reported Challenges Faced by DOD in Implementation and Utilization; Airlines Cost analysis Cost effectiveness analysis Data collection Data integrity Defense appropriations Defense cost control Defense economic analysis Defense procurement Economic analysis Financial management Interagency relations Military forces Military personnel Program evaluation Program management Reporting requirements Requirements definition Standards evaluation Systems conversions Systems testing Travel Travel costs Official travel Program implementation Defense Travel System
