The adoption of these technologies can have a significant impact on the process of information creation and dissemination. The result of this impact has typically been measured unidimensionally, in terms of the quantity of information produced (Lyman and Varian, 2003).

Designing for ROI: toward a value-driven discipline for e-commerce systems design

To be effective in today's competitive environment of e-commerce, e-businesses cannot afford to neglect justifying the return on investment (ROI) of their online operations. Ideally, companies would like to understand how users are using their Web site and how this translates into value creation (or value leakage) so that online solutions can be implemented to increase business performance.

We employ March's (1991) model for organizational learning in the context of knowledge management and analyze the effectiveness of the codification and personalization strategies in different organizational settings.

In recent years we have seen the emergence of electronic marketplaces that leverage information technology to create more efficient markets such as online auctions to bring together buyers and sellers with greater effectiveness and at a massive scale.

However, the impact of these technologies on the quality of information is unclear. In this paper we develop a framework for the process of information production and use it as the basis for an economic model that captures a publisher's decision to produce information.

In this chapter, we examine the extent to which online consumer purchases are effectively supported through systems design choices in Web-based applications through a series of five classical stages in consumer purchase decision-making.

We find that the existence and the amount of prior social relations in the network do increase the probability of an OSS project to attract more developers. Interestingly, for projects without preexisting social ties, developers tend to join the project initiated by people with less OSSD experience.

However, the general recognition of the importance of such systems seems to be accompanied by a technology-induced drive to implement systems with inadequate consideration of the fundamental knowledge problems that the KMS are likely to solve.

However, different diagrammatic representations of the same information may vary in the computational efficiency of working with these diagrams. The objective of this research was to explore the effects of diagrammatic representations on the task of integrating multiple diagrams. The domain of systems analysis and design was used to generate examples and test the theory.

Using data from US manufacturing industries, we find that industries receive significant IT spillover benefits in terms of total factor productivity growth through economic transactions with their respective supplier industries.

We conducted an experiment with methodology designers who have invented one of the major object-oriented methodologies and programmers who have used the methodology for their projects. Concurrent verbal protocols were analyzed based on a theoretical framework which views programming as search in four problem spaces: representation, rule, instance, and paradigm.

Many scholars and practitioners have identified an OSS project's ability to attract and retain developer interest as a key factor influencing its sustainability and success. Although what motivates individuals to participate in OSS development in general has been investigated extensively, little information exists regarding which specific OSS project they choose to contribute to.

Ideally, senior managers whose companies are investing money in Web sites that support Internet-based selling would like to understand how customers are using their Web sites and how this translates into business value so that online solutions can be implemented to increase overall business performance.

So, one of the most pressing issues is whether the design of their online storefronts is effective, and if not, which areas require attention and improvements. However, current approaches (eg, user testing, inspection, inquiry) are not well suited to the task at hand. This paper proposes a new business value-driven approach to website evaluation, which is grounded in the economic theory of production.

The perceptual integration process involves establishing interdependencies between the relevant data that have been dispersed across multiple diagrams, while the conceptual integration process involves generating and refining hypotheses by combining the individual data inferred from the diagrams.

In this article, we explore the basis for developing a new approach to the evaluation and the prioritization of software development activities that modify the capabilities of Web sites in terms of the quality of services that they can deliver to a firm's customer-users.

As information systems are embodiments of application domain knowledge and technical knowledge, ISD requires both in order to be effective.
