Measuring the success of mobile government (m-government) is a significant challenge faced by the public sector today, as governments are increasingly using mobile technology to provide public services to citizens and m-government endeavors have often fallen short of their potential. To address this gap, we draw on DeLone and McLean’s (2003) updated information systems (IS) success model in order to develop an m-government success model that theorizes service quality as comprising online and offline service quality and further uses perceived value to measure net benefits. The results of a survey of 286 m-government users in China indicate that information quality and online service quality, but not system quality, are positively associated with citizen satisfaction, which in turn is positively associated with perceived value. The results also show that the relationship between online service quality and citizen satisfaction is positively moderated by offline service quality, while citizen satisfaction partially mediates the relationships between information quality/online service quality (but not system quality) and perceived value. This study extends the updated IS success model by differentiating between online and offline service quality, as well as by introducing the notion of perceived value. Our results provide guidance to researchers and practitioners regarding the role of service quality and perceived value in measuring m-government system success. 相似文献

Developing a strong and positive information technology (IT) service climate is important to ensure high-quality IT services. The influence of job resources and personal resources on the IT service climate and the mediating effect of the IT service climate on IT service quality were explored in this study qualitatively and quantitatively. Among the various job resource factors, we found that training, reward, and information system (IS) support can improve the IT service climate. Coworker support shows a non-significant effect on IT service climate. Among the personal resource factors, self-efficacy and hope have significantly positive effects on the IT service climate. Optimism and resilience do not appear to significantly affect the IT service climate. Our results confirm that the IT service climate is an important mediator in enabling certain antecedents to properly impact IT service quality. The IT service climate was found to fully mediate the effects of training, reward, IS support, and hope while partially mediating the effect of self-efficacy. The effect of the IT service climate on IT service quality is also strengthened by a high customer contact frequency. The results presented here may provide scholars and practitioners with a comprehensive, workable understanding of the IT service climate. 相似文献

移动团购发展迅速,用户的持续使用意愿是移动团购发展和竞争的关键,ECM、IS成功理论以及两者整合研究是持续使用意愿的主要方式,哪个模型对用户的持续使用意愿解释力度更强是本文研究的主要问题。本文以移动团购为研究对象,基于ECM和IS成功理论比较和整合研究用户的持续使用意愿,构建研究模型。通过调查问卷收集数据,使用SPSS和Smat PLS分析数据,进行假设检验。研究发现ECM、IS成功理论以及两者整合研究模型均适用于持续使用意愿研究,且ECM对于满意度和持续使用意愿的解释力度均大于IS成功理论,而整合理论的解释度最强,整合研究模型更适合于研究用户的持续使用行为。移动团购的满意度受到期望确认、感知有用性和系统质量、服务质量的影响,且期望确认以及感知有用性的影响作用更大,而信息质量的影响作用不显著。 相似文献

IS research predominantly presumes that the success factors of IT service have one-dimensional influences: the higher (or lower), the better. Sporadic arguments, however, have been made that, depending on the antecedent, such a monolithic premise may not sustainable. Despite the rich evidence of the dichotomous role of success factors on measured consequences in non-IS fields, especially in the marketing discipline, theoretical and empirical efforts to examine this duality have received limited attention in IS research. Especially, no previous IS study took the extended duality position in which the role of success conditions can be any of pure enabler, pure inhibitor, asymmetric bi-directional influencer or symmetric bi-directional influencer . The extended duality becomes the theoretical thesis of this research, setting it apart from the scant IS research that viewed duality through the rather simplified lens of statistical significance in each direction. To test the validity of the extended duality theory in the IT service context, cross-sectional survey data were gathered on post-adoption usage of mobile data services (or MDS), the most prevalent form of IT service. Frequently used success conditions of IT service – system quality, information quality, economic value and self-efficacy – are chosen as the explanatory variables. The analysis suggests that success conditions of IT service can have a highly divergent and diversified form of duality effects on measured outcomes. The findings have important practical and theoretical implications to practitioners and researchers. 相似文献

Sigma is a metric that quantifies the performance of a process as a rate of Defects-Per-Million opportunities. In clinical laboratories, sigma metric analysis is used to assess the performance of laboratory process system. Sigma metric is also used as a quality management strategy for a laboratory process to improve the quality by addressing the errors after identification. The aim of this study is to evaluate the errors in quality control of analytical phase of laboratory system by sigma metric. For this purpose sigma metric analysis was done for analytes using the internal and external quality control as quality indicators. Results of sigma metric analysis were used to identify the gaps and need for modification in the strategy of laboratory quality control procedure. Sigma metric was calculated for quality control program of ten clinical chemistry analytes including glucose, chloride, cholesterol, triglyceride, HDL, albumin, direct bilirubin, total bilirubin, protein and creatinine, at two control levels. To calculate the sigma metric imprecision and bias was calculated with internal and external quality control data, respectively. The minimum acceptable performance was considered as 3 sigma. Westgard sigma rules were applied to customize the quality control procedure. Sigma level was found acceptable (≥3) for glucose (L2), cholesterol, triglyceride, HDL, direct bilirubin and creatinine at both levels of control. For rest of the analytes sigma metric was found <3. The lowest value for sigma was found for chloride (1.1) at L2. The highest value of sigma was found for creatinine (10.1) at L3. HDL was found with the highest sigma values at both control levels (8.8 and 8.0 at L2 and L3, respectively). We conclude that analytes with the sigma value <3 are required strict monitoring and modification in quality control procedure. In this study application of sigma rules provided us the practical solution for improved and focused design of QC procedure. 相似文献

Information systems (IS) service organizations are increasingly more concerned with their ability to co-create digital services with customers in service ecosystems. Practitioners and researchers, however, lack understanding of which organization mechanisms effectively contribute to IS organizations’ innovation practices. Grounded in service-dominant logic, we hypothesized that process reference frameworks (PRFs), such as the IT Infrastructure Library (ITIL), act as institutional arrangements through their norms, rules, and practices, enhancing IS organizations’ ability to innovate digital services. Data collected from 159 IS organizations confirmed our hypotheses, showing that effects on digital service innovation are mediated by an organization’s digital service climate and co-creation practices. This study makes four major contributions. First, our results contribute to the literature on service-dominant logic and the role of institutional arrangements in facilitating service innovation in service ecosystems. Second, our study offers a novel understanding of PRFs’ role in value co-creation and digital service innovation. Third, by introducing the digital service climate from existing theoretical frameworks that might assist in conceptualizing the role of culture and shared meaning, our study contributes to further theorizing on the social factors that influence service ecosystem practices. Finally, our findings can motivate IT managers to consider using PRFs to develop capabilities for creating business value together with customers. 相似文献
