Effective Training has been recognized as one of the most important success factors for enterprise resource planning (ERP) system operations. However, both ERP system vendors and user companies have failed to provide an effective training method for users because practical business process cases cannot be formalized. Also, incomplete testing by ERP system vendors results in insufficient and ineffective user training. This paper suggests a scenario framework for ERP testing and training (SF-ETT). SF-ETT is constructed by expanding the practice-based ERP testing scenario construction framework designed for uniERPII. SF-ETT contains concrete business process entities that users understand actually and provides practice definition, notation, and architecture.

To rapidly respond to uncertainties in the business environment whilst remaining competitive, every organization needs to be able to successfully introduce and manage organizational change. Cognizant of the role of information systems (IS) as an enabler of organizational change, many organizations have paid attention to Enterprise Resource Planning (ERP) systems for successful organizational change primarily because of their change-driving forces across organizations. In this study, we focus attention on the role of readiness for change in the ERP systems adoption. Readiness for change described as views about the need for organizational change is posited to be and antecedent of two expectancies about the need for organizational change is posited to be an antecedent of two expectancies about the system. performance expectancy and effort expectancy, which lead to actual system use. In order to further establish th relevance of readiness for change as a determinant of two expectancies, computer self-efficacy is considered to be other key predictor as well. In addition, this study proposes that the personal characteristics of organizational commitment and perceived personal competence play roles of important determinants of readiness for change. Based on data gathered from the users of the ERP systems, structural equation analysis using LISREL provides significant support for the proposed relationships. Theoretical and practical implications are discussed along with limitations.

배치작업(Batch Job)이란 ERP 시스템에서 제공해야 하는 기능중의 하나로 스케쥴링하여 정해진 시간에 사용자의 interaction이 없이 오프라인(off-line)으로 서버에서 자동으로 실행시키는 작업을 말한다. ERP 시스템의 성능을 향상시키기 위해서는 기존의 사용자와 interactive한 오프라인작업을 효율적으로 운영하고 이를 모니터링/통제하는 기능에 더하여, 기업 업무를 오프라인으로 처리하는 시스템이 개발되어야 한다. 작업 부하가 많이 소요되는 작업이나 주기적으로 처리되는 작업은 작업부하가 상대적으로 낮은 시간을 택하여 수행하도록 하여 시스템의 부하를 경감시키고 작업 효율을 향상시킬 수 있다. 본 논문에서는 기존에 개발된 ERP 시스템에 오프라인처리를 위한 배치 작업 시스템 개발에 대해 연구하였다. 기존에 온라인 작업과는 독립적으로 작업을 오프라인으로 실행시킬 수 있도록 개발되어 시스템의 작업 부하를 경감시키고 시스템의 유휴시간을 활용하여 효율을 증가시킬 수 있어, 전체적인 시스템의 성능을 향상시킬 수 있다.

정부는 중소기업의 업무성과(업무처리의 신속성과 능력 향상, 정확한 자료관리, 고객 대응 능력 향상, 의사결정의 신속성)를 높이고자 하는 목표를 가지고 다양한 정보화사업을 시행하고 있다. 본 연구는 이러한 목적으로 2001년부터 산업자원부가 지원한 3만개 중소기업의 ERP(Enterprise Resource Planning) 시스템의 도입에 따른 업무성과에 영향을 미치는 요인들을 파악하고자 한다. 이를 위하여 설문조사를 실시하였으며, 총 1022개의 설문응답을 회수하였다. 설문의 업무성과 응답이 5점 서열척도임을 고려하여 이에 적합한 ordered probit 회귀분석을 실시하였다. 분석 결과는 모든 종속변수들과 유의한 관련성을 가지는 독립 변수는 사용용이성, 시스템 안정성, 정보의 정확성, 그리고 정보의 다양성으로 나타났다.

This paper reports on a contingency framework for selecting the most appropriate strategy to implement the enterprise Resource Planning(ERP) system in an organization. The two dimensions of our framework are information technology level and culture level of organization. For each of the four contingencies, we recommend a desirable implementation strategy, based on scope and pace of the implementation effort. ERP implementation data from ten organizations were analyzed to validate the proposed framework.

The enterprise resource planning (ERP) system is a standardized and advanced business process that many companies are implementing now-a-days through customization. However, it affects the efficiency of operations as these customizations are based on uniqueness. In this study, we analyzed the impact of customized modules and processing time on customer service request (CSR), by utilizing the stacked CSR data during the construction and operation of ERP, focusing on small and medium-sized enterprises (SMEs). As a result, a positive correlation was found between unit companies and the length of ERP implementation; ERP modules and the length of ERP implementation; ERP modules and unit companies; and the type of ERP implementation and ERP module. In terms of CSR, a comparison of CSR processing time of CBO (customized business object) module and STD (standard) module revealed that while the five modules did not display statistically significant differences, one module demonstrated a statistically very significant difference. In sum, the analysis indicates that the CBO-type CSR and its processing cost are higher than those of STD-type CSR. These results indicate that companies planning to implement an ERP system should consider the ERP module and their customization ratio and level. It not only gives the theoretical validity that should be considered as an indicator for decision making when ERP is constructed, but also its implications on the impact of processing time suggesting that the maintenance costs and project scheduling of ERP software must also be considered. This study is the first to present the degree of impact on the operation and maintenance of customized modules based on actual data and can provide a theoretical basis for applying SW change ratio in the cost estimation of ERP system maintenance.

Enterprise resource planning(ERP) in nature entails large scale business process redesigns and the corresponding risks. To reduce such risks, enterprise modeling(EM) approach could be adopted through which ERP is planned and effectively implemented on a consistent basis throughout the entire organization. The scope of this paper is to report on EM experiences and lessons learned in the process of ERP implementation. Through a case study, this paper presents and EM methodology which takes due account of strategic business processes, information flows, organizational requirements, and their interdependencies. To assess the impact of distributed application scenarios on effective ERP implementation, alternative EMs have been created and evaluated whether they support information requirements for strategic decisions and day-to-day operational activities, core business processes, and business functions as required. Practical issues and problems raised in the EM process have been discussed.
