초록

성공적인 프로젝트 수행을 위해서 개발초기 단계에서 소프트웨어 개발노력 등 자원을 예측하는 것은 매우 중요하다. 그리고 이는 소프트웨어 규모를 통해 가능하며, 소프트웨어 규모 산정 방식의 최근 동향은 프로그램 라인 수(LOC)와 같은 개발자 관점의 접근방식 보다는 사용자가치 중심의 산정방식인 기능점수 분석기법(FPA)을 보다 선호하고 있다. 따라서 본 논문에서는 사례연구를 통해 실제 투입되는 개발노력을 측정하고, 완전기능점수 기법 매뉴얼에 따라 COSMIC Function Point를 직접 계산하였다. 그리고 산출된 데이터에 대한 회귀분석을 통해 COSMIC-FFP기반 소프트웨어 개발노력 추정 모델을 제안한다. 그리고, COSMIC-FFP 기법은 규모를 추정하는데 필요한 기능 요소들에 대한 가중치를 적용하지 않는 단점이 있다. 따라서, 본 연구에서는 제안된 모델의 정확성을 높이기 위해 시스템 복잡도를 가중치로 적용하며, 가중치 추정을 위한 모델도 제안한다.

It is very important to forecast a back resource of a software development effort at the early stage of development life cycle for successful project processing, and it is carried out through software size estimation. The recent trend of software size estimation method is focused on the user's value such as FPA. We measure the actual development effort through case study and calculate CFP directly according to the cosmic-ffp manual V.3.0. in this paper. We also propose the software development effort estimation model by using the produced data. COSMIC-FFP does not use weights of necessary function elements, and so it has disadvantage in estimating sizes. This paper proposes the estimation model to estimate the precision software size by using system complexity as weight.
