초록
시간이 지남에 따라 정보시스템의 교체여부를 고려해 볼 때, 기업 및 공공기관에서 요구하는 기능 및 성능을 지속하면서 교체나 재개발에 소요되는 비용을 최소화하기 위해서는 정보시스템을 구축한 후 어느 정도 사용 후에 교체할 것인가에 대한 교체시기가 중요하다. 이와 같은 정보시스템의 경제적 수명 추정에 있어 기존의 이론들은 사용된 연수에 따라 변화하는 정보시스템의 잔존가치를 가정된 데이터에 의존하였다. 이러한 가정들을 이용하여 교체시기를 결정함으로써 새로운 정보시스템의 도입, 교체시기가 경제적으로 타당성을 갖지 못하게 되었으며 실질적인 비용의 증가를 초래하였다. 본 연구에서는 이러한 문제를 해결하기 위한 하나의 방법으로 지금까지 연구된 이론을 기초로 실제 정보시스템이 구축되고 운영되면서 발생한 모든 비용을 고려하여 정보시스템의 경제수명을 객관적으로 입증함으로써 정보시스템의 경제적인 수명을 예측할 수 있는 하나의 방법을 제시하고자 한다.
Abstract
Corporations and government agencies that require the replacement or redevelopment of the features and performance, while continuing to minimize the costs of information systems built with the first degree, and then after use should be the decision of whether to replace. Existing theories used to study the changing value of information systems were supposed to rely on data. Using these assumptions by determining when to replace the introduction of a new information system, replacing the period from becoming an economically feasible and resulted in a substantial cost increase. In this study, as a way to eliminate this problem so far been studied on the basis of the theory is built and operating as a real information system, taking into account any and all costs of information systems, information systems similar to economic life by demonstrating to consider the economic life to provide an economical way to be.
