In this paper, EVMS procedure for KHP program is presented. Research and development of a defense system as a long lead program has a high probability of cost growth due to the uncertainty and risk. Therefore, meeting schedule, technical performance and preventing excessive cost overrun are the main concerning point to successful research and development program. EVMS(Earned Value Management System) is a program management system using earned value to control cost, schedule and technical performance. In order to control cost and schedule and to meet technical performance requirements of the KHP research and development program, it is necessary for us to adapt EVMS to the program.
