This thesis analyzes the reengineering efforts of the Department of Defense (DoD) travel system. It includes a functional economic analysis of the DoD travel system, design of a new travel system for the Naval Postgraduate School (NPS), and a framework for reengineering the travel system. This framework has been developed for the travel system, but can be applied to any DoD reengineering efforts. The analysis of the reengineering efforts is completed with a comprehensive look at lessons learned. The research concluded that reengineering projects need senior management participants, full time cross-functional eams, and an environment for change.
