The IT implementation literature suggests that various implementation factors play critical roles in the success of an information system; however, there is little empirical research about the implementation of data warehousing systems has unique characteristics that may impact the importance of factors that apply to it. In this study, a cross-sectional survey investigated a model of data warehousing success. Data warehousing managers and data suppliers from 51 organizations completed paired mail questionnaires on implementation factors and the success of the warehouse. The purpose of this study is to identify which factors have a positive impact on the successful implementation of DW among organizational implementation success, project implementation success, and technical implementation success which are selected as implementation factors of DW. To do so, this study comprehensively analyze the previous studies on the success factors of the information system and DW to develop the study model and set the hypothesized. Then, it verified the hypothesis via the empirical analysis after collecting the materials through the survey. Finally, the discussion of the study's results, offered the implications of the findings, and the conclusions of the findings followed.

Although Enterprise Systems (ES) have promised major strategic benefits and process improvements from business and technology integration, their implementation has been plagued by a high failure rate and difficulty in realizing the promised benefits. For the purpose of understanding implementation failures, previous studies have focused on identifying critical success factors (CSFs) for information systems implementation. However, there has been little research on how these CSFs actually lead to successful results. In this study, based on process theory, we examined the process of ES implementation by explaining how the factors of ES implementation influence each other and how interaction among them produces results. Based on a failure case, we then developed a process model of ES implementation thus allowing us to explain the process of ES implementation. The proposed model facilitated an understanding of how repeating patterns of ES failure can be reversed. This model can be used for guiding new ES implementation projects.

Project implementation plan is a blueprint that confirms project performance activities and specifies required man-hour, period and resource imput ratio. Various figures, the results of implementation plan, are predicted through estimation, and because of superiority of objectivity and repeatability, numerical formula-based estimation model is often used overseas. COCOMO model is the representative estimation model whose theories and formulas are publicized and it predicts the total man-hour required for software system development. This model is publicized in "Software Engineering Economics" written by Professor Barry Boehm of the U.S., and is the most widely applied numerical formula-based estimation model. This study is conducted to provide a series of methods that are optimal for KTDS environment by choosing COCOMO II model among various types of COCOMO models. In establishing implementation plan, COCOMO II model alone is not sufficient, it is necessary to link with and apply standard WBS system and standard man-hour. In establishing specific implementation plan, phased standard WBS system in order of the first phase of all the activities implemented in the project, Activity, Task, and Role, and the man-hour put into this should be distributed according to standard ratio from COCOMO II model's total man-hour. This study provides explainations by establishing standard WBS system and linking with COCOMO II model.

The management science was concerned about how to use the main point of the management science model and it's technique by the rational primary factors. The problem's definition, estabilished of the model and it's solving. These function are very difficult and important problems, what is more important, are the model of management science's real prosecution to the manager and management scientist. The management science give us a clue to the solution of a business problem. To get needs conclusion and achieving the estabilished object, we must implement a plan, a stratgem, a policy. If we were not implementing the recommended items, we may call the estabilished model and problem solving impractical, ivory-tower theorizing. But, the implementation of management science model is a complicated problem that is involved mutual relations of managers and management scientist, linkage parts member and the resources of organization. And the other problems of implementation are very complicated problems composed of technologic and economic, social and politic, psychological. This paper reports the implementation of a success that possibly studies a fluent and a chief cause to systematic analysis. Then, first of all I will define of implementation and from these, construction of a unity system, I continue with a catch hold of a main point and a fluent for the successful implementation.

This paper proposes a new registry model for systematically referencing standards in e-Business field. We have many systems that provide standards and additional information. However, there are several problems such as inefficient standard information, dependency on a standard type, high standard information acquisition cost, no relations between standard information, and so on. In this paper, a new registry model and its prototype implementation are described. The proposed model is defined based on ISO/IEC 11179-Metadata registries, which is one of the international standards for interoperability between data. The proposed model provides an integrated- systematic standard information support, and also considers technology stack and business processes for e-Business systems. This paper develops a prototype for the proposed model and implementation result. Finally, to show the contribution of our proposal, this paper shows the comparative evaluation between previous systems and our proposal with various comparative items.

The controls of Information Systems (IS) have been an more critical issue controls as the sophistication and integration of IS is more proceeded. ITGI (The Information Technology Governance Institute) of ISACA (Information Systems Audit and Control Association) has suggested COBIT (Control Objectives for Information and related Technology) and this has been widely recognized the evaluation model of IS controls. In COBIT, IS was evaluated in terms of process, information quality, and IT resources. This study used COBIT in order to suggest and empirically test an evaluation model of IS service. The data was collated from one major Chinese SI (Systems Integration) company in four domains of processes : planning and organization, acquisition and implementation, delivery and support, and monitoring. Seven factors are extracted using an exploratory factor analysis as follows : Overall IT planning process, technological assessment process in IT planning of IT, cost-benefit assessment process in IT planning, implementation process, support process, monitoring process, post-implementation evaluation process. The results of confirmatory analysis of three alternative measurement models indicated that the measurement model with one inherent or conceptual variable has greater model fitness than the other models. This study suggests the logical and general way to test and apply COBIT in evaluating IS services.

현재 EJB(Enterprise Java Beans), COM+(Component Object Model+)등의 서로 다른 컴포넌트 참조 모델(Component reference model)을 기반으로 한, 상이한 컴포넌트 시스템 간 통합(Integration)에 대한 새로운 기술들이 제기되고 있다. 동일한 컴포넌트 플랫폼에서 컴포넌트 간 운용은 소스레벨의 결합(Composition)을 통해 이루어진다. 그러나 상이한 컴포넌트 플랫폼의 경우, 유사 도메인 컴포넌트임에도 불구하고 컴포넌트 간 결합은 불가능한 실정이다. 본 논문에서는 상이한 컴포넌트 플랫폼 즉, EJB와 COM+ 컴포넌트 간의 결합 문제를 모델기반의 컴포넌트 변환 기법으로 해결 하였다. EJB, COM+ 컴포넌트 간 결합을 위해 각 참조모델을 비교, 분석하여 구현 독립적(Implementation Independent)인 가상 컴포넌트 모델(Virtual Component Model)과 상호 변환을 위한 구현 테이블(Implementation Table)을 제시하였다. 가상 컴포넌트 모델과 구현 테이블을 참조, 각 구현 모델을 가상 컴포넌트 모델로 일반화하거나 가상 컴포넌트 모델링을 통하여 플랫폼의 구현 독립적인 가상 컴포넌트 모델을 작성하고, 선택적으로 EJB와 COM+로 변환 가능하게 한다. 상이한 컴포넌트 플랫폼으로의 효율적인 모델변환 방법을 제시함으로서 EJB와 COM+ 컴포넌트간의 결합이 가능하다.

Many researchers and practitioners have paid much attention to identifying some critical factors for the successful implementation of the TPS, EDP and MIS. However, not much effort have been focused on the implementation issues of DSS which is different from TPS or MIS in terms of the scope of the system, evaluation criteria, decision types served, and level of users. Because of these differences, implemention of DSS should be planned and approached from different aspects of TPS, EDP and MIS. A conceptual model includes four characteristics as independent variables and three dependent variables such as system usage, user's satisfaction, and user's attitude. This paper is to empirically prove the usefulness of the model and to identify a model for the successful implementation of DSS in Korea. It will provide a better understanding of the variables associated with the successful DSS implementation.
