E-commerce success is an issue that has attracted the interest of many pundits. There is a general scarcity of models and frameworks for evaluating e-commerce success. Whether traditional information systems success models can be extended to investigating e-commerce success is yet to be investigated. This paper proposes a partial extension and respecification of the Delone and Maclean model of IS success to e-commerce systems. Customer Ecommerce Satisfaction (CES) is proposed as a dependent variable to e-commerce success and its relationships with e-commerce system quality, content quality, use, trust and support are defined and discussed. Further research into developing, validating and empirically testing the model is proposed. Keywords: E-commerce, E-commerce systems success, Customer e-commerce satisfaction, Delone and Maclean 1.

Companies are finding that the development of World Wide Web presence sites is becoming a competitive necessity, particularly the need to establish online storefronts. Even so, there are few useful frameworks in the electronic commerce (EC) literature to help managers identify online opportunities and what types of applications can add business value to the user. I expand on an existing framework originally developed by Hammer and Mangurian [1] to identify opportunities from Web-based EC applications. I argue that firms compete along 5 dimensions of commerce: By using various modes of interaction, firms compete over both time and distance to provide some product or service to their customers through a chain of relations. In addition, new investments in information technology are typically justified using 3 different criteria—generating efficiency, effectiveness, and/or strategic benefits. These 2 perspectives can be combined to create the Electronic Commerce Value Grid, which identifies 15 areas in which managers can use Web-based electronic storefronts to add value for their customers.

This paper describes a case study focused on redesigning procurement processes for research grants management at the U.S. Office of Naval Research. These processes focus on the procurement of R&D services, and how they can be redesigned and supported using Web-based capabilities. Through the application of empirical results and theoretical concepts from business process reengineering, electronic commerce, and IT-based process management, we gain insight into issues and challenges to be addressed in redesigning the procurement of contracted services with Web-based EC capabilities. Accordingly, four research questions are identified and addressed which build from these results and concepts. Finally, in collaboration with other participants in this effort, the case study reveals that we could contribute to a substantial reduction in process cycle time and operational costs associated with the annual funding of thousands of research grant procurement actions at ONR.

This report gives an overview of metadata management in general (Part I) and on the role of metadata for data warehousing (Part II). Because of the complexity and extensive applicability of metadata, a compact, precise definition of the notion may hardly be provided. Therefore, we explain metadata by illustrating the use and the forms it may take within various application areas. In the case of data warehousing, we present a classification of metadata along certain dimensions and we discuss significant aspects of metadata management that have to be considered for the construction of a data warehouse system. Furthermore, this report provides a comprehensive survey and analysis of the state of the art of metadata management in industry and research. The most important standards for representation and interchange of metadata, commercial products and research projects are presented and discussed (as far as the available information allows) for both, the general case and the part...

In this paper we highlight the fact that existing Pay-TV schemes operating on countries or world regions could be transformed into a global system as the digital television broadcasting technology offers the possibility to put different regional content (e.g., audio and subtitle information) into one transmission so that each user could decode the content according to his personal needs. As the Internet could be used for selling Pay-Per-View licenses and the digital multimedia content can be played by personal computers the existing Pay-TV systems could become a global electronic commerce solution reducing the transmission cost per content significantly.

Electronic Commerce (E-Commerce) has become a popular topic for business and academic research since the early 1990's. Different researchers focus on different areas: applications, services, marketing, strategy, the Internet, extranets and technologies in E-Commerce, to name but a few. Yet despite this focus on E-Commerce, there is still confusion about just what it is. The aim of this paper is to investigate the still comparatively limited number of E-Commerce Frameworks/Models and to see whether it is possible to develop a truly dynamic model for E-Commerce researchers and practitioners. The model we have developed, which is based on theoretical research at this stage attempts to include all the components and extensions of E-Commerce thus far identified. This model is still at an early stage of development, and we will continue to modify it as empirical evidence adds to its completeness.

With the increasing popularity of commercial uses of the Internet, business-to-business (B2B) e-commerce and e-procurement are moving corporate purchasing to the World Wide Web. E-procurement systems are computer systems and communication networks through which firms buy and sell products. We identify two types of e-procurement systems: extranets and electronic markets. Extranets connect the buyer and its suppliers with a closed network. In contrast, electronic markets create open networks for buyer and supplier interactions. The differences between these two types of e-procurement channels lie in system implementation costs, marketplace benefits, and the extent of supplier competitive advantage that develops due to information sharing. In this article, we develop a new theoretical model to analyze the adoption of e-procurement systems from the buyer’s perspective, to explore the set of conditions under which the buyer will prefer to procure via an electronic market instead of using proprietary extranet connections. The primary finding is that a buyer will adopt an e-market approach when the supplier’s competitive advantage derived from access to strategic information is modest compared with the variable net benefit that the e-procurement channel generate. We also find that the buyer is likely to have a bigger trading network with an e-market than with an extranet in order to capture the greatest available benefits. Overall, this study offers guidelines for managers to design and select e-procurement channels to fit different procurement needs.
