SaaS (Software as a Service) provides software in the form of service via internet rather than software package. Thus a large number of users could use the service of new type of software service as long as they connect to internet. SaaS, as a delivery model attracted in the software industry, grows with impelling force. SaaS has been adopted as an information spreading strategy of small and medium corporate so that its effect has been recognized in both academic and practical areas. However, there are not much researches about it because SaaS is still in the introductory stage. This study focused on the success model of SaaS to find out the factors that affect usability and the satisfaction of users. The sample is based on the on-line survey for the 549 government officials who are using SaaS. At last, the number of the employed answers are 157 after unqualified ones are removed. The result shows that Security, Service quality, Price and System Integration significantly affect the usefulness and the satisfactions of users.

Recently, an introduction of the cloud computing causes rapid changes in every aspect of the internet environments including hardware, operating systems, applications, and their services. As the cloud computing environment based on SaaS are being developed to a form in which web platform technology and web cloud services are converged. The digital library system also has been being developed to a service model optimized to SaaS based cloud computing environment, which are different from ASP technology. From the web interface point of view, user customization of the SaaS based cloud computing environment is the most important fact. Therefore, this research work suggests a customized web interface considering usability and accessibility so that enterprises and individual users can be able to do an effortless internet browsing under the cloud computing environment. For this purpose, usability tests were carried out as the user customized web interface design were developed and applied to the LinkSaaS website. This paper work lastly presents an UI environment on which customized interface design for individual users can be formulated.

Software as a service (SaaS) is one of the most-talked about trends in IT. Unlike traditional perpetual licensing model, software applications are sold on subscription bases and services are provided over web by the vendors. It is said that SaaS can make vendors to invest more on R&D than on marketing while offering its customers better quality software applications at lower costs. By empirically comparing vendors providing their software applications either by SaaS or by traditional perpetual licensing model, we examine whether or not SaaS really increases overall customer benefits in terms of cost efficiency, software quality, and customization. We show that SaaS may not provide better quality or cost efficient software applications than perpetual licensing does. Then we provide two practical tools which are useful for customers to evaluate whether SaaS is better than perpetual licensing for the purposes of software applications they want to adopt.

Business organizations today have sought management effectiveness and efficiency utilizing information technologies. In particular, small and medium-sized enterprises short of information resources tend to rely more on outsourcing for accomplishing their own information strategies. SaaS(Software as a Service) has recently become one of the powerful outsourcing alternatives. This study tries to identify the influence of the SaaS quality on the service performance and loyalty. A SaaS quality model is developed including tangibles, reliability, responsiveness, assurance, and empathy. Then they are hypothesized to have influence on the service performance defined as user satisfaction, individual performance, and organizational performance. Service performance is considered to have an impact on the loyalty to service. Findings from a survey to test hypotheses on the relationship among SaaS quality, performance and loyalty show these variables are significantly important to widespread adoption of SaaS.

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.

디지털 기술의 급속한 발전으로 시간과 공간의 제약이 없는 인프라 환경이 구현되면서 더욱 더 유연하고 빠른 적응성에 대한 요구가 정치, 경제, 문화 전반에 확산됨에 따라 IT 기술을 통해서 이러한 요구를 충족시킬 수 있는 서비스로 대두되고 있는 것이 바로 클라우드 서비스이다. 이러한 클라우드 서비스 시대의 개막은 관련 기업뿐만 아니라 공공기관, 개인에 이르기까지 모든 영역의 서비스 이용자들의 삶에도 큰 변화를 가져올 것이다. 그러나 클라우드 서비스에 대한 기존의 논의는 주로 사업자의 입장에서 클라우드 비즈니스 모델의 발굴, 수익 모델의 발굴, 클라우드 기술 발전에 따른 전망 등에 초점을 맞추어져 왔다. 따라서 정작 클라우드 서비스 이용자는 상대적으로 낮은 관심을 받아온 것이 사실이다. 이는 새로운 기술에 비즈니스 모델이 등장하면 반복되던 현상이 클라우드 서비스 분야에서도 반복되고 있는 것으로도 볼 수 있다. 본 논문에서는 클라우드 서비스중 SaaS 서비스의 이용자 측면에서 서비스 이용행태를 분석하고 이를 기반으로 향후 SaaS 서비스의 전망에 대하여 논의하고자 한다. 이를 위해 SaaS 서비스 이용자를 현재 서비스를 이용하고 있는 이용자군과 현재에는 SaaS 서비스를 이용하지는 않지만 향후에는 서비스를 이용할 의도를 가지고 있는 잠재이용자군로 구분하여 설문조사를 수행한 설문결과를 토대로 이용자의 이용행태를 분석하고 향후 SaaS 서비스 전망을 기술하기로 한다.
