摘要：This study develops an alternative methodology for the risk analysis of information systems security (ISS), an evidential reasoning approach under the Dempster-Shafer theory of belief functions. The approach has the following important dimensions. First, the evidential reasoning approach provides a rigorous, structured manner to incorporate relevant ISS risk factors, related countermeasures, and their interrelationships when estimating ISS risk. Second, the methodology employs the belief funct...

摘要：Previous studies surrounding the DeLone and McLean model of information systems (IS) success have called for future research and further examination of its measure in different contexts. We draw from the literature on strategic IS planning and organizational culture to contextualize the DeLone and McLean model. There is some evidence that a high-quality information technology (IT) plan leads to system success; therefore, we empirically examine the inclusion of the IT plan quality construct as ...

摘要：Information technology (IT) value remains a serious concern of management today, especially how it should be measured and how it is created. Although we have made significant progress at the firm and aggregate levels of analysis, process-level analysis is still in its infancy, and there is a need for a systematic basis for identifying IT effects. We provide such an approach by developing two models: a process performance model of how system characteristics enhance process output and quality an...

摘要：Advances in information and communications technology have made possible collaborative activities in virtual settings. Virtual settings can significantly expand the knowledge resources available, yet they also create additional challenges to the already difficult activities of collaborating. The purpose of this research is to provide a better understanding of how collaborative activities in virtual settings enable the different parties to achieve their desired objectives by examining them from...

摘要：eXtreme Programming (XP) is a well-known agile software development method. While a number of reports have been published on explaining the XP methodology and the perceived benefits when using XP for system development in recent years, less is known about the actual operationalization of the XP principles. This paper presents an action research study reporting on the experiences of implementing the XP methodology in a development project for a Web-based, distributed information system. The goa...

摘要：What is the role of information technology (IT) in enabling the outsourcing of manufacturing plant production processes? Do plant strategies influence production outsourcing? Does production process outsourcing influence plant performance? This research addresses these questions by investigating the role of IT and plant strategies as antecedents of production outsourcing, and evaluating the impact of production outsourcing and IT investments on plant cost and quality. We develop a theoretical ...

摘要：The concept of collective efficacy within virtual teams has yet to be studied. This study developed and rigorously validated a domain-specific measure of collective efficacy, entitled virtual team efficacy, within a comprehensive research framework. Over a two-year period we collected field study data from multiple samples of information systems project teams-in all, 52 virtual teams comprising 318 students from the United States, Great Britain, and Hong Kong. As we hypothesized, group potency...

摘要：We examine a knowledge management (KM) success model that incorporates the quality of available knowledge and KM systems built to share and reuse knowledge such as determinants of users' perception of usefulness and user satisfaction with an organization's KM practices. Perceived usefulness and user satisfaction, in turn, affect knowledge use, which in our model is a measure of how well knowledge sharing and reuse activities are internalized by an organization. Our model includes organizationa...

摘要：Personalized services are increasingly popular in the Internet world. This study identifies theories related to the use of personalized content services and their effect on user satisfaction. Three major theories have been identified-information overload, uses and gratifications, and user involvement. The information overload theory implies that user satisfaction increases when the recommended content fits user interests (i.e., the recommendation accuracy increases). The uses and gratification...
