摘要:This study investigates the effect of varying project complexity on the group interaction processes of small information technology (IT) project teams. The projects included two complex tasks (i.e., LAN and WAN development tasks) and a less complex development task (i.e., a small business Web site development task). The study found that project complexity can affect the group interaction process. Participants reported significantly higher expectations, group integration, communication, and par...

摘要:The Internet search engine market has seen a proliferation of entrants over the past few years. Whereas Yahoo was the early market leader, there has been entry by both lower-quality engines and higher-quality ones (such as Google). Prior work on quality differentiation requires that low-quality products have low prices in order to survive in a market with high-quality products. However, the price charged to users of search engines is typically zero. Therefore, consumers do not face a tradeoff ...

摘要:Although user satisfaction is widely used by researchers and practitioners to evaluate information system success, important issues related to its meaning and measurement across population subgroups have not been adequately resolved. To be most useful in decision-making, instruments like end-user computing satisfaction (EUCS), which are designed to evaluate system success, should be robust. That is, they should enable comparisons by providing equivalent measurement across diverse samples that ...

摘要:In this study, we conduct an empirical analysis of the performance of five popular data mining methods-neural networks, logistic rearession, linear discriminant analysis, decision trees, and nearest neighbor-on two binary classification problems from the credit evaluation domain. Whereas most studies comparing data mining methods have employed accuracy as a performance measure, we argue that, for problems such as credit evaluation, the focus should be on minimizing misclassification cost. We f...

摘要:This study seeks to assess the business value of e-commerce capability and information technology (IT) infrastructure in the context of electronic business at the firm level. Grounded in the IT business-value literature and enhanced by the resource-based theory of the firm, we developed a research framework in which both the main effects and the interaction effects of e-commerce and IT on firm performance were tested. Within this theoretical framework, we formulated several hypotheses. We then...
