TCO 접근방법을 통한 정부클라우드 SaaS 서비스 전환의 타당성에 관한 연구

A Study on the Validity of Government Cloud SaaS Service Migration using TCO Approach

It is well known that SaaS(Software as a Service) changeover gives several advantages to organization. One of the advantages is the cost reduction effect of IT resources as well as IT human resources. Another one is the curtailment of software development workload in the field of informatization promotions. Nonetheless, it is hard to find comparison cases regarding the quantitative measurement of the introduction of SaaS before and after. Accordingly, when the Government IDC tries to adopt SaaS, it absolutely needs the empirical study whether SaaS is cost-effectiveness or not. In this study, we focus on variation in the Government administration common tasks, processes and labor costs. Using the Man-Month(MM) estimation methods. We verify that how much TCO(Total Cost of Ownership) is reduced per year.
