This paper describes the differences of the information system's success factors to improve the end-user's performance according to the job characteristics. A modified model of DeLone and McLean's IS success model is proposed with the two added variables of the top management concern and the IS department support. The model is validated using data collected from a field study of 3872 users on 3 Korean companies. ANOVA, correlation analysis, and stepwise regression are used to test research hypotheses. The results of the study indicate the following implications. First the top management concern and the IS department support have the significant relation with the system usage and the user satisfaction. Second, the system quality has an influence on the user satisfaction more than on the system usage. And the information quality has an influence on the system usage more than on the user satisfaction. Third, the system usage has more relations to the user's performance in the logistics function and R&D function. The user satisfaction has more relations to the user's performance in the sales and the A/S function. Therefore information system strategy to increase the user's performance must be differentiated according to job characteristics.

At the center of the repeating evolution of IT industry, there is mobile computing in the ubiquitous environment, and the increasing usage of smart phones contribute more to its growth. P corporation co-developed with Google and implemented smart work system called SWP for the purpose of 'communication and collaboration with co-workers' beyond the general goal of increasing productivity and comfort of employees. The primary objective of this study is to objectively analyze the influence of the effect factor from end user's perspective and user satisfaction on SWP usage, intention for continuous usage and individual performance. To accomplish this research purpose, this study established research models and hypothesis by collective review about information system success models, and tested the research hypotheses using the structural equation modeling technique by data collected from 320 SWP system users of P corporation. Variations for system satisfaction evaluation standard are 1)SW system usage 2) intention for continuous usage 3) individual performance, effect variations are 1) social factors 2) technical factors 3) combination of social and technical factors. Therefore, this study is about influence factors on success of SWP system and how the factors impact the outcome. The test results of this research model is summarized as follows. Firstly, system user's satisfaction had positive impact on all three; SWP system usage, intention for continuous usage and individual performance. Secondly, social factor 'SWP control system' and technical factor 'information quality' and 'system quality' had positive impact on SWP system user satisfaction, while social factor 'shared value' and technical factor 'service quality' did not have significant effect on user satisfaction. Shared value however, had interactive effect with 'information quality' and 'service quality'. This study is expected to contribute to spread of academic research on smart work system by suggesting a model that can show important factors for corporation while explaining the successful implementation of SWP and its continuous usage.

The purpose of the present study is to empirically and theoretically assess the logistics information systems (LIS) success in a quasi-voluntary IS use context. It is important to understand what factors impact the successful use of LIS. The research model is basically based on the framework of IS success proposed by DeLone & McLean(1992) and Seddon(1997). Structural modeling techniques were applied to data collected by questionnaire from 203 LIS users. The results show that user satisfaction play a significant role in influencing the system dependency. The results also revealed that user characteristics is directly affected by perceived usefulness, system quality and information quality, and indirectly influenced by user characteristics.

IT발전의 따른 산업분야의 정보시스템은 기업 또는 프로젝트의 생산성 향상과 전략적 경쟁우위를 점하게 하는 필수적 지원도구 중 하나로 인식되고 있다. 이러한 정보시스템의 효과를 극대화하기 위해서는 정보시스템의 성과에 영향을 미치는 성공요인들을 규명하는 과정이 필요하다. 왜냐하면, 이러한 성공요인을 활용하여 IS의 성과달성 또는 성공여부를 예측하거나 또는 성공에 이르는 메커니즘을 규명할 수 있기 때문이다. 하지만, 우리나라에서 건설프로젝트 참여자의 의사가 반영된 웹 기반 PMIS의 성공모델에 대한 연구는 미흡한 실정이며, 따라서 웹 기반 PMIS의 성과달성 또는 성공 메커니즘 역시 아직 규명되지 않은 상태이다. 따라서 본 연구의 목적은 기존 연구에서 널리 활용되고 있는 DeLone and McLean의 수정된 IS 성공모델[5]에 근거하여, 웹 기반 PMIS가 국내 건설프로젝트에서 국내 건설기술자에 의해 활용되는 상황에서, 웹 기반 PMIS의 성공요인이 사용자 사용의도와 만족도 어떠한 영향을 미치는가를 분석하는 것이다. 분석을 위한 건설 PMIS의 성공요인은 연구자의 선행연구에서 타당성 및 신뢰성이 검증된 을 항목을 활용하였으며. 건설 PMIS의 성공변수는 사용의도 및 사용자 만족도로 설정하여 기존 정보시스템 성공모델에 관한 문헌고찰을 통해 평가항목을 구성하였다. 실제 PMIS의 사용자인 시공사, 사업관리자를 대상으로 설문조사를 실시하였으며 이렇게 수집된 자료들로 통계프로그램인 SPSS 12.0을 활용하여 다중회귀분석을 통해 건설 사업에서 웹기반 PMIS의 성공요인과 사용의도, 사용자 만족도간의 영향관계를 분석하고 시사점을 도출하였다. 이 연구에서 제시하는 웹 기반 PMIS 성공모델을 통해 검증된 성공요인은 시스템 평가와 성공 예측 등에 활용 가능하며, 연구 결과 제시되는 시사점들은 향후 보다 설명력 높은 성공모델 구축의 방향 설정에 기여할 것이다.

With a focus on different aspects of PMIS in construction projects, various sets of critical success factors (CSFs) have been suggested in the literature such as IS Success Model by various researchers. It is crucial to explore the relative importance and groupings of these factors. This paper aims to identify CSFs associated with Project Management Information System (PMIS) in construction projects, and explore their ranking and underlying relationship. CSFs for PMIS identified through a literature review, and consolidated by interviews and pilot studies with professionals in construction industry. A questionnaire instrument was sent out to experienced users (Construction Manager and Constructor) in Korea, and 253 completed questionnaires were retrieved. To increase the generalizability of the results, the respondents were spread across construction site. Using factor analysis and considering the high importance of the factor, CSFs were grouped into three dimensions. All these three groupings and their relationship were included in a framework for successful PMIS in construction projects. These findings help to clarify what the high prioritized factors are, and could also be used as an assessment tool to evaluate the performance of PMIS and thus help to identify areas for improvement.

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 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 results from a regression analysis of the data identified relationships between the system quality and data quality factors and perceived net benefits. It was found that management support and resources help to address organizational issues that arise during warehouse implementations, resources, user participation, and highly-skilled project team members increase the likelihood that warehousing projects will finish on-time, on-budget, with the right functionality; and diverse, unstandardized source systems and poor development technology will increase the technical issues that project teams must overcome. The implementation's success with organizational and project issues, in turn, influence the system quality of the data warehouse; however, data quality is best explained by factors not included in the research model.

This paper classifies the success factors of collaboration system in the shipbuilding industry. We propose the structural model that identifies the relationship between the success factors and organizational performance. To test empirically the relationship between the factors, we developed the measurement of each factors. This paper has examined the relationship between the independent variables and the mediating variables, also has examined the relationship between the parameters and a final dependent variable. The independent variables are as follows, (1) quality of system including reliability, flexibility, and accessibility, (2) the quality of information including contents, expressiveness, and (3) the partner relationship including the information sharing and the compatibility of strategies. The mediating variables are user involvement, parter trust, and user satisfaction. The final dependent variable is business performance. The hypotheses test proved that the system quality significantly affect user satisfaction, the information quality positively influence on the user participation, and the information sharing and strategic fit of partner relationship positively affect partner trust. Also, the user participation and partner trust significantly affect user satisfaction. Finally, the user participation, user satisfaction, and partner trust have a decisive effect on the organizational performance. The results of hypothesis test verified that the quality of information and system, also partner relationship are important to operate successfully the collaboration system in the shipbuilding industry. Also, the mediating variables are important to explain the structural relationship between the independent variables and organizational performance.
