An Empirical Study on the Relationship between Competitive Strategy and e-Business Performance by e-Business Development Stages
Park, Yong-Jae ; Chung, Kyung-Soo ;
The Journal of Information Systems, volume 16, issue 2, 2007, Pages 1~33
Selecting and implementing competitive strategies based on e-business is extremely important since it determines if an enterprise can continue to grow or not. Accordingly, systematic and empirical study on the implementation of e-business based on competitive strategy is required, and in-depth studies considering various e-business development stages of enterprises are also needed. The purpose of this study is to present guideline for the staff in charge and managers of enterprises to achieve competitive advantage and to increase organizational performance in e-business environments. What we have found are as follows. (1) Factors greatly influencing on competitive strategy selection through e-business were environmental uncertainty, centralization, innovative culture, technological competence, and formalization. (2) Results of the relationship between competitive strategies and e-business performance showed that each strategy had different effects on financial performance, process performance, and customer performance. and (3) Data analysis between internal and external environmental factors and competitive strategy by each e-business development stage proved that the relationships between competitive strategy and e-business performance were different based on e-business development stage. Implications of the study and guidelines for the managers are provided in the paper.
A Study on the Implementation and Practical Application of Web Monitoring System
Park, Chul-Jae ; Cho, Jae-Gyeun ;
The Journal of Information Systems, volume 16, issue 2, 2007, Pages 35~49
The web monitoring is a procedure to detect and monitor the change of a particular information from the web site. In this paper, we propose a monitoring system to survey the response time for the customers chi an internet shopping mall. This system we designed, decreases the network overload and guarantees the accuracy as well as the reliability of the information by using an interactive agent. This interactive agent we constructed, is written in Java and controlled by the high-level information such as the index or the robot. from the N web site, we extracted the web monitoring results of keyword "LCD Monitor" and verified our system's efficiency. The performance of the system is tested and the result is illustrated.
Perceived Usability of e-Government Web Sites Affecting the User Satisfaction and the Revisiting
Byun, Dae-Ho ;
The Journal of Information Systems, volume 16, issue 2, 2007, Pages 51~68
The previous studies regarding the usability evaluation of e-government web sites focused only on deriving affecting factors and variables. They did not find the relationship of usability, user satisfaction and revisiting. The objective of this paper is to find the causal effect how the usability of e-government web sites affect to the user satisfaction and the revisiting attitude. no scope of e-government web sites included the portal site and ie liked web sites. We developed a structural equation model and performed a user test. As a result, a perceived usability affected the revisiting, but it did not intermediate the user satisfaction.

The mobile computing environment has already matured and mobile services are activated throughout many industries. In the following years, these changes are expected to evolve into a ubiquitous computing environment. In the meantime, whether newly developed information technologies will thrive or diminished depends on user's intention to adopt them. Hence, the necessity of user-centered research considering ubiquitous computing in mobile computing environment is obvious. This study, thus, investigated ubiquitous factors in various literature related to ubiquitous computing and technology acceptance and it proposes a research model of the ubiquitous factors affecting user's intention to use mobile services, in terms of meaning(connectivity, mobility), service(contextual offer), compatibility(compatibility), and infrastructure(privacy, truth). The proposed model is expected to help both researchers and practitioners extend their understanding about the ubiquitous factors in mobile computing environment
A Study on the Industrial SWOT Analysis and Benefits for the Successful RFID Implementation
Chang, Yun-Hee ;
The Journal of Information Systems, volume 16, issue 2, 2007, Pages 93~122
RFID has fundamental influences on today's business management. This research seeks to formulate the opportunities and challenges, the strengths and weaknesses and the perceived benefits of RFID implementation in three industries: manufacturing, medical-service, and distribution. Ten companies of successful RFID deployment in Korea are presented. Field interview and panel discussion were used to explore the research purpose. The core challenges include RFID readability issues, lack of best practices, increasing prime cost, visible ROI, implementation cost, and employee's resistance. The strengths include IT infrastructure, system integration competency, RFID business model creation ability, executive's support. There is little weakness in Korea companies, there are many perceived benefits in three industries. The most distinctive finding is that the visible ROI was found out in the manufacturing industry, not in the distribution industry. The opportunities and challenges, the strengths and weaknesses and the perceived benefits are some different in three industries, which provide valuable guidance for Korean companies in seeking the RFID opportunities. This case study represents a pioneer research of RFID adoption in Korea.
Perceived Trust of e-Marketplace and Its Effect on Commitment, Long-Term Orientation and Cooperation
Park, Jun-Cheul ;
The Journal of Information Systems, volume 16, issue 2, 2007, Pages 123~144
As the interest in the business-to-business electronic commerce is increasing, many companies are participating in the business-to-business e-marketplaces. As a result, it is important to develop understanding of behaviors of firms that use these e-marketplaces. For this purpose, e-marketplace usage company trust is proposed to affect commitment, long-term orientation and cooperation. This study, which used data from participating in the business-to-business e-marketplace companies, showed acceptable data-fit of proposed model and supported all of research hypotheses. The empirical results indicated that trust take significant effect on commitment, long-term orientation and cooperation, and the commitment affect long-term orientation and cooperation, and the commitment in turn have strong influence on long-term orientation and cooperation. It was confirmed that commitment variable is effective mediator linking trust and long-term orientation and cooperation.

The purpose of this research is to investigate success factors of knowledge management in Korea companies. The research scheme was experimented through a questionnaire survey answered by 87 companies. The research model was composed of five groups : 1) CEO support and business strategics, 2) organization culture 3) information technology characteristic of knowledge workers 4) a reward and performance measurement 5) knowledge management system. The results of this research indicated that the CEO support and organization culture are important factors for knowledge activities. The information technology characteristic of knowledge workers and a reward have small effects for knowledge activities. Manufacturing companies and non-manufacturing companies need different knowledge management strategies. The results of this study will be helpful for the success implementation of knowledge management in Korean companies.
