Many companies have attempted to strengthen competitiveness by introducing information technology ERP system in a changing and global competitive business environment. However, ERP systems can not meet all the requirements that occur in the enterprise. After the system introduced, When it operates with existing systems or with new systems, the need for strong interface technology along with the appearance of the ERP have been gradually increased. In this paper, we selected SAP R/3 system as a typical ERP system. Among the modules of SAP R/3, MM module was chosen. Interface technologies for SAP R/3 Systems integrate mulltiple R/3 systems and non R/3 systems, and play important roles in expanding the company's business process. VBA approach was implemented as the data interface design between SAP R/3 and other systems. It proved to reduce the feeling of resistance from user's point of view. It also proved to improve the operational efficiency in a convenient input and output manner of purchase request data.

This dissertation searched for a social function and role of university, and problems of information-oriented universities through the analysis of the present conditions of university ERP systems in Korea. The purpose of this study is to find main success factors by investigating case studies on university ERP systems (university own development systems, Korean ERP systems, foreign ERP systems, etc.) and by referring to documentary records on the existing research. Especially this study observed university management. from an innovative aspect by studying success factors for information-oriented university connecting general functions of universities like education, research, and administration service, etc. This study result will suggest outline effective and practical implementation strategies for university administration information systems.

In the past few years, many Korean companies have implemented various ERP systems. Despite the enormous efforts and costs, however, there have been doubts about the effectiveness of ERP implementation. The purpose of this study is to identify whether the announcement of ERP implementation affects the market value of the firm. To achieve the research objective, event-study methodology was used assessing the cumulative abnormal returns(CARs) for 33 firms' announcements of ERP investments. Findings of the study are summarized as follows: First, the announcements of ERP implementation have no effect on the firm value though the sign is negative. Second, there is marginally significant difference in the market value of the firm between the first mover of ERP implementation and its followers. In order to figure out any possible reasons of such unexpected results, several investors and fund managers of major investment firms were interviewed. They reached the two agreements that ERP hardly increases the firm value. One was mainly due to the misfit between the foreign business processes built in the ERP systems and Korean firms' traditional business processes. The other was the possibility of financial deterioration caused by substantial costs for ERP implementation.

ERP, a typical enterprise application, helps companies to increase their productivity and to support their decision makings. ERP is composed of diverse functions that are optimized under PC environment, whereas the ERP applications on a mobile platform have many constraints such as a small screen, limited resolution, and computing power. Because all the functions of a ERP legacy system are not required for ERP on a mobile device, the core functions of the ERP system should be selected to increase system efficiency. In this study, two main methods were used; interviews and log analyses. The end users using a ERP system were interviewed for their perceptions, and log data analyses were made for the hitting number of specific ERP functions. The differences between the actual usage based on log data and users' cognitive preferences about ERP functions were analysed. Finally, the functional differences between users' perception and actual usage were suggested for some practical implications.

ERP implementations are known to be unusually difficult, even when compared to other large-scale systems developing in a firm level, because it requires a substantial investment of time, money, and internal resources. Moreover, medium and small-sized enterprises that are increasingly adopting ERP feel much difficult due to the lack of resources. To promote the spread of ERP in medium and small-sized enterprises, "ERP template standardization methodology" led by government has been used for constructing ERP system in Korea. In this study, we present a study to measure fitness between ERP standard templates and business processes of 10 small enterprises in 5 industries. Also, we define a fitness measure suitable for this purpose. We car find that ERP template standardization methodology is partly adequate to establish ERP systems and it is required to add to templates which support the differences of business process.

Recently, an ERP (Enterprise resource Planning) system has been becoming an essential S/W tool for companies to manage their business processes and manufacturing resources. As the information exchange becomes more complex, not only corporate companies but also small- and mid- sized enterprises (SMEs) are required to build an ERP system. However, for small- and middle- sized companies, the adoption of ERP systems becomes challenging due to high cost and long installation time of the system. This paper presents a novel concept of an adaptive ERP system incorporating the ontology structure of the business supply chain information. The proposed ERP installation methodology is illustrated with an example of a door-trim manufacturing company in the automotive supply chain.

Based on investigating and analyzing the cases of advanced foreign universities that have already included ERP courses in their education systems, this study proposed the ways of incorporating ERP courses into Korean universities' curriculums in terms of the following three areas: 1) development of ERP courses, 2) establishment and maintenance of ERP education environment, 3) continuous evaluation and improvement of ERP education implementation. As reasonable ERP courses, "Introduction to ERP" targeted to educating overall basic concepts in ERP system and business administration, "ERP System Implementation" for fostering business process design and system implementation skills, "ERP Programming" such as ABAP for the purpose of customizing ERP system, and "Strategic Use of ERP" dealing with ERP package selection and implementation methodologies of effective utilization of ERP systems were suggested. Regarding the establishment and maintenance of ERP education environment, single server architecture model that contained both database and application was proposed with the intention of set-up cost saving and maintenance efficiency. As for the evaluation and improvement on ERP education implementation, its methodologies were introduced through analyzing the advanced cases. Finally in addition to the above three areas, critical success factors for effectively launching ERP education in the universities were suggested through reviewing the previous case studies.

경영환경의 급속한 변화와 정보시스템의 발달로 인해 기업은 경쟁력 강화를 위해 끊임없는 노력과 혁신을 하고 있다. 최근에는 국내외 많은 기업들이 기업 경쟁력 강화를 위해 ERP(Enterprise Resourse Planning)를 이미 도입하였거나 또는 도입할 예정으로 있다. 2) 이러한 ERP시스템이 이전에는 대형 기업을 중심으로 한 시스템 구축이 주류를 이루고 있었다. 하지만 최근에는 국내 ERP업체들의 활성화로 인해 독자적인 ERP 패키지의 개발로 중소기업을 위한 ERP구축 사례가 늘어나고 있다. 이렇게 기업 경쟁력을 제고시키는 수단으로 각광을 받고 있는 ERP 시스템은 제조, 물류, 유통, 인사/회계 관리 등의 업무프로세스를 정보기술로 구현한 대형기술로 제조기업의 모든 기능을 망라한 전사적인 통합솔루션으로서 단순히 정보 기술차원의 접근 방법이 아닌 정보기술과 비즈니스의 조화를 이루려는 경영 전략 차원의 접근 방법이다. 3) 본 논문에서는 ERP 시스템의 성공적인 구축 경험을 바탕으로 I기업(중소기업)을 대상으로 ERP 구축 사례를 소개하고자 한다. 먼저 I기업의 정보화 수준 측정을 통해 ERP 구축 전 기업의 경영환경과 정보시스템 활용도 및 사용자 만족도를 파악하고, ERP 시스템을 도입하게 된 배경과 구축 과정 및 결과와 기대 효과를 분석하고자 한다. 마지막으로, ERP 시스템 구현의 성공적인 요인들을 찾아내어 앞으로의 연구 방향을 제시하려 한다.
