A Study of Factors Influencing the Price of ERP System in its Implementation
The Journal of Information Systems, volume 12, issue 1, 2003, Pages 1~17
ERP is a topic of currency in MIS circle. Numerous organization have developed their information systems using many kinds of ERP packages such as Oracle, SAP R/3, uniERP, etc. However, the pricing methodology of ERP systems is not yet established in a proper way. This paper attempts to investigate factors influencing the price of ERP system. Thirty eight ERP consulting firms participated in this research project. Based on the data from ERP consulting firms, price of ERP systems basically consist of package cost, consulting fee, and customizing expense. The results of this research project are finding factors affecting above three parts that consist price of ERP system. This paper found that factors influencing package price are number of modules, number of users, the degree of package reliability. The factors affecting consulting fee are the degree of project specialty, level of consultants. Finally the factors influencing customizing cost are the degree of project difficulty, project time.
The Impact of Organizational Context on the Performance of ERP Systems
The Journal of Information Systems, volume 12, issue 1, 2003, Pages 19~45
The ERP system comes to existence in the period of change. In other words, the ERP system is adopted to the company with BPR project. In general, the ERP system is introduced to companies as packages rather than in-housing systems. There are several researches in IS literatures which have a conclusion that organizational context affects the performance of ERP system. This study attempts to review the organizational context from the prospective of organizational structure and change management. Regarding the organizational structure, we choose some widely known variables such as the degree of formalization and centralization. For the analysis of change management, we set the variables, which are the most importantly considered, such as the power of CEO's promotion and user participation. The extent of customizing is introduced as moderating variables between the organizational context and the implementation performance. With collected data, we performed the reliability test, the factor analysis and the regression analysis. In summary, the introduction of an information system such as ERP system has a behavioral and organizational impact. The organizational change may breed resistance and opposition and can lead to the failure of the system. Therefore, implementation of the system requires careful change management, active involvement of users and high level of management support.
Success Factors for ERP System Performance
The Journal of Information Systems, volume 12, issue 1, 2003, Pages 47~66
This study was examined the relationship between the exogenous and endogenous variables in our model to measure ERP system performance using path analysis. The exogenous variables are system quality, user participation, user training, top management support and self-efficacy, and the endogenous variables are system usage, user satisfaction, and work efficiency. The results of the study are shown as follows. First, all the exogenous variables in our model have a direct effect on user satisfaction, and system quality, training, and self-efficacy have a direct effect on system usage. Second, system usage has a direct effect on user satisfaction and user satisfaction has a direct effect on work efficiency. The findings show that the exogenous variables in the model are important to increase ERP implementation success.
Design and Implementation of a Mobile Office System for Delivery Service
The Journal of Information Systems, volume 12, issue 1, 2003, Pages 67~85
In the recent a mobile internet makes a change in internet business. The mobile internet service is resulting in M-commerce. Even if M-commerce provides only information service, there will be much possibilities to make applications in various areas such as, delivery service, trading service, banking service etc. in the near future. Delivery service requires many steps in processing, originally. This study is designed to implement a mobile system which makes short in delivery process. It includes that a delivery man receives a signature on a paper and input data at the delivered place by using PDA at hand. The mobile system will be contributed to shorten delivery speed. It is proposed to implement the mobile office system for improving service efficiency in the business of delivery service.

Design and Implementation of Component-Based XML/EDI System
The Journal of Information Systems, volume 12, issue 1, 2003, Pages 87~116
One of the important applications for business-to-business electronic commerce is in procurement and inventory management using electronic data interchange(EDI). Using online catalogs and approved supplier lists, firms can easily create requisitions and purchasing documents. The emerging trend in EDI technology is changed from VAN(Value Added Network) based EDI to XML based EDI. This paper intends to suggest a component-based XML/EDI system using Unified Modeling Language(UML), as an application system for automobile part industry. Applying component based XML/EDI systems designed with UML methodology, we analyzed the workflow and the document on procurement process between trading partners and implemented a prototype of efficient XML/EDI system, as a surrogate of existing VAN/EDI. The result of applying object-oriented CBD(Component Based Development) technique is to minimize the risk of life cycle and facilitate the reuse of software as mentioned to limitation of information engineering methodology. It enables the interoperability with corporate legacy systems such as ERP(Enterprise Resource Planning), SCM(Supply Chain Management). This system proposes a solution to apply analysis phase and design phase in implementation of XML/EDI system. The implementation of XML/EDI system using CBD shows the ease of use in software reuse and the interoperability with corporate internal information system. The purchasing department with XML/EDI system can electronically communicate purchase orders, delivery schedules to external suppliers and interoperate with other application systems.
The Influence of Media, Consumer, and Product Characteristics on Perceived Risk and Purchasing Intention
The Journal of Information Systems, volume 12, issue 1, 2003, Pages 117~144
The purpose of this study is to be aware of the relationship between the perceived risk and purchasing intention after investing the impacts by 3 factors-consumer, media, and product characteristics on the perceived risk. The influence on perceived risk is categorized based on the 3 factors' combinations. The result of this study shows that the each characteristics of media, consumer, and product affect consumer's perceived risk and also this risk is affected by the relationship among these 3 independent variables. These results mean that the consumer's perceived risk about buying goods at the internet shopping mall or TV home shopping cannot be measured by a single dimension. Finally, it has a negative relationship between the perceived risk and purchasing intention. Implications for managers' use of shopping media are discussed in terms of the product and media characteristics fit.
A methodology for selecting workflow software products: AHP approach
The Journal of Information Systems, volume 12, issue 1, 2003, Pages 145~158
Workflow is the automation of a business process, in whole or part, during which documents, information or tasks are passed from one participant to another for action, according to a set of procedural rules. The software selection problem is made difficult by the multiplicity of competing products and the lack of expertise and experience of users in the methods of software evaluation. Although the selection process for workflow is similar to that proposed for the acquisition of any software packages, differences arise in their evaluation criteria and choice methods. In this paper, we suggest the Analytic Hierarchy Process(AHP) method for selecting workflow software. The AHP is an intuitively easy method for formulating and analyzing decisions. It was developed to solve a specific class of problems that involves prioritization of potential alternate solutions. We showed how to evaluate 9 commercial workflow products by deciding the relative importance of the main criteria in the AHP model. We utilized the evaluation data for criteria ready suggested by specialist groups. Our methodology will be helpful to those who are going to adopt a best workflow product in their organizations. Although the criteria and their evaluation scores regarding workflow products are suggested, it is not easy to apply them to a real case and get solutions without a model.
Web-based QA Workflow System for Radioactive Waste Disposal
The Journal of Information Systems, volume 12, issue 1, 2003, Pages 159~175
During the early stage of radioactive disposal programs, important issues related with quality assurance of data sets, methodologies, R&D procedures are recognized as important ones. This paper focused on the development of web-based workflow standards for the QA procedures of the radioactive waste disposal programs. The flow of process was analyzed based on workflow concepts proposed by the Workflow Management Coalition (WfMC). QA system is based on the principles of T2R3. T2R3 Workflow was used to standardize and restructure the business and/or work process in the industry or organization. The WfMC has identified five functional interfaces to a workflow service as part of its standardization program. They are composed of process definition interface, worklist handler, application program interface, interface between workflows, and system management. The task flow and QA program were defined based on the workflow ideas. QA procedures for the R&D results of radiation disoposal were analyzed following the reference model of workflow. In addition, six program run list were created and implemented. The creation, revision, and approval of the test data were designed to be inplemented on the web environment. Through this system, R&D procedures such as planning, research, documentation, internal review and future independent peer review processes could be well organized and stored more systematically on the database and knowledge base. This will encourage the usage and data sharing between interested parties through it's clear and transparent workflow standards.
