무기체계 획득과정에서 비용추정은 여러 가지 이유에서 매우 중요하며, 필요한 절차이 다. 타 사업과 비교하여 예산 지원 가능성을 판단하는데 필요한 의사결정을 지원하거나, 연간 예산 소요 판단치를 결정하며, 사업추진 단계별 필요한 자원할당과 임무수행 효과 판 단에 활용되기도 한다. 더욱이 비용추정을 통해 사업의 투명성과 효율성을 증가시키는 역 할도 갖고 있다. 본 연구에서 제안한 비용추정 절차는 지금까지 적용되고 있는 비용추정 방법론을 개선 하였다. 즉, 연구개발 사업을 중심으로 비용추정 절차를 프로젝트 정의, 비용추정 방법론 적용, 비용추정치 산출의 3개 영역으로 구분하고, 각 영역별로 3개 단계를 세분화하여 체 계적인 비용추정 과정을 제안하였다. 또한, 여기에서 제시된 3개 영역 9개 단계를 실제 연 구개발 사업의 추진 단계인 개념연구, 탐색개발, 체계개발, 생산, 운영유지 단계별로 비용 추정 적용 방법을 제안하였다.

Cost estimates are necessary and important for weapon system acquisition process for many reasons to support decisions about funding one program over other, to develop annual budget requests, to evaluate resource requirements at key decision points, and to develop performance measurement baselines. Moreover, cost estimating has a role for enhancing transparence and efficiency of a project. This paper improves existing cost estimating methodology. In this study cost estimating processes which consists of three areas, project definition, cost estimating methodology and developing estimates. Each area has a detailed three steps. Finally, cost estimating applications are suggested with developed concepts in this study for R&D projects life cycles which are Conceptual Study, Preliminary Design, System Development, Production and Test & Evaluation, and Operation & Maintenance phase
