Abstract

Estimation of development cost, effort and time is difficult and a key problem of software engineering in the early stage of software development. These are estimated by using the function point which is measured from a requirement specification. However, it is often a serious Question of the staffing level required for the software development. The purpose of this paper is to show us the model which can be used to estimate a size of development team. Three hundred one software projects have been analyzed and studied for the model. First, an analysis was conducted for statistical algorithmic model. After various data transformation and regression analysis, it was concluded that no good model was available. Therefore, non-algorithmic model was suggested for analysis, which has random distribution of residuals and makes good performance using RBF (Radial Basis Function) network. Since the model provides a standard to determine the required size of development team, it ran be used as management information.

소프트웨어 개발 초기에 개발비용, 소요인력과 기간을 추정하는 것은 소프트웨어공학 분야에서 어렵고도 중요한 문제이다. 이 정보들은 소프트웨어 요구사항 명세서로부터 측정된 소프트웨어 규모인 기능점수를 이용하여 추정한다. 측정된 소프트웨어 규모를 개발하기 위해서는 개발팀을 몇 명으로 구성할 것인가가 문제로 제기된다. 본 논문은 소프트웨어 개발팀의 규모를 추정할 수 있는 모델을 제시한다. 모델을 유도하기 위해 301개 소프트웨어 프로젝트들이 사용되었다. 먼저, 통계적 알고리즘 모델인 회귀모델을 연구하였다. 다양한 데이타 변환과 회귀분석 결과 좋은 성능의 모델을 얻지 못하였다. 따라서, 비알고리즘 모델인 RBF망을 적용하여 잔차가 랜덤하게 분포하고 우수한 성능을 가진 모델을 제안하였다. 본 모델은 소프트웨어 개발에 필요한 개발팀 규모에 대한 기준을 제공함으로써 인력관리 정보로 활용할 수 있다.
