摘要：Internet traffic pricing is necessary for the vitality of electronic commerce because uncontrolled congestion creates a detrimental effect on quality of the Internet services. Pricing approaches based on negative externality have potential to address the issue of congestion. However, most externality-based pricing approaches require the knowledge of consumers' private demand characteristics, and this requirement is often pointed out as the single most important shortcoming of these mechanisms....

摘要：This paper proposes a four-tiered framework for classifying and understanding the myriad of information systems development methodologies that have been proposed in the literature. The framework is divided into four levels: paradigms, approaches, methodologies, and techniques. This paper primarily focuses on the two intermediate levels: approaches and methodologies. The principal contribution of the framework is in providing a new kind of deep structure for better understanding the intellectua...

摘要：Software preannouncements are often called vaporware (systems or features announced long before a ship date). The challenge confronting software vendors and consumers is understanding the balance between the need to inform the market and the negative consequences of unfulfilled promises. Based on signaling theory from marketing science and research, this study looks at the perceived importance of software preannouncement factors on customers, of unfulfilled promises and unreliable software on ...

摘要：Today, a second generation of computer-based reengineering tools employs knowledge systems technology to automate and support key intellectual activities required for effective process redesign. But a central question remains as to the effectiveness of redesign through such knowledge systems. The research described in this paper is focused on testing the effectiveness of knowledge-based, process-redesign systems. We employ one such system, called KOPeR-lite, as a platform for experimentation t...

摘要：Provided the increasing prevalence of electronic exchange environments-including propriety electronic data interchange (EDI) and some Internet-based EDI (e-commerce) systems-we argue that management's decision-making focus vis-g-vis electronic data interchange (EDI) assumes a tactical disposition rather than a strategic one. We offer that the formulation and execution of tactics may be organized around the general question of how to effectively integrate EDI with internal systems, since this a...

摘要：A key issue facing IT researchers and practitioners has been the difficulty in realizing strategic payoff from IT investment. This study, drawn on sociological theories of embeddedness, addresses this key issue, with particular attention to the perspective of EDI network initiator. Cross-case analysis is conducted comparing three initiators of sophisticated EDI networks, who realized different levels of strategic payoffs. Results reveal that the achievement of strategic payoffs is a function o...
