The governance of an organizational information technology (IT) infrastructure is steadily shifting away from pure hierarchical and market mechanisms toward hybrid and partnership modes that involve external vendors. In particular, IT outsourcing has recently emerged as a significant administrative innovation in an organization's IT strategy. This paper seeks to explore the sources of influence in the adoption of this innovation. For this purpose, we generated a comprehensive sample of outsourcing contracts in the US using an electronic bibliometric search process. Using diffusion modeling, our empirical analysis shows that the adoption of IT outsourcing is motivated more by internal influence (or imitative behavior) than by external influence amongst the user organizations. Subsequently, we considered the widely-publicized Eastman Kodak's outsourcing decision as a critical event to assess whether this internal influence is more pronounced in the post-Kodak regime than in the pre-Kodak regime. Our results show that internal influence is dominant in the post-Kodak regime but not in the pre-Kodak regime. Implications and directions for future research are discussed.

Online spaces that enable shared public interpersonal communications are of significant social, organizational, and economic importance. In this paper, a theoretical model and associated unobtrusive method are proposed for researching the relationship between online spaces and the behavior they host. The model focuses on the collective impact that individual information-overload coping strategies have on the dynamics of open, interactive public online group discourse. Empirical research was undertaken to assess the validity of both the method and the model, based on the analysis of over 2.65 million postings to 600 Usenet newsgroups over a 6-month period. Our findings support the assertion that individual strategies for coping with “information overload” have an observable impact on large-scale online group discourse. Evidence was found for the hypotheses that: (1) users are more likely to respond to simpler messages in overloaded mass interaction; (2) users are more likely to end active participation as the overloading of mass interaction increases; and (3) users are more likely to generate simpler responses as the overloading of mass interaction grows.

The theoretical model outlined offers insight into aspects of computer-mediated communication tool usability, technology design, and provides a road map for future empirical research.

An important area of information systems (IS) research has been the identification of the individual-level beliefs that enable technology acceptance such as the usefulness, reliability, and flexibility of a system. This study posits the existence of additional beliefs that inhibit usage intentions and thus foster technology rejection rather than acceptance. We theorize that these inhibitors are more than just the antipoles of enablers (e.g., the opposite of usefulness or reliability) and so are distinct constructs worthy of their own investigation. Inhibitors are proposed to have effects on usage intentions beyond that of enablers as well as effects on enablers themselves. We report on a series of empirical studies designed to test the existence and effects of inhibitors. A candidate set of six inhibitors is shown to be distinct from enablers. These inhibitors are subsequently tested in a field study of 387 individuals nested within 32 different websites. Effects at both individual and website unit levels of analysis are tested using multilevel modeling. We find that inhibitors have negative effects on usage intentions, as well as on enablers, and these effects vary contingent upon individual or website unit levels of analysis. The overall results support the existence and importance of inhibitors in explaining individual intent to use—or not use—technology.

As a result of newer communication technologies and an increase in virtual communication, employees often find themselves multicommunicating, or participating in multiple conversations at the same time. This research seeks to explore multicommunicating from the perspective of the person juggling multiple conversations at the same time—the focal individual. To better understand this phenomenon, we extend previous theorizing by including the concepts of the episode initiator (whether the second conversation was focal or partner initiated), the fit of the set of media used in the episode, one process gain (conversation leveraging), and process losses. Employing a series of pilot studies and a main study, the resulting model was analyzed using structural equation modeling, finding overall support for the model. Findings suggest that experienced intensity is an important factor influencing process losses experienced during multicommunicating, whereas episode initiator influences process losses and the process gain. Further, media fit moderates the relationship between intensity and process losses. The importance of multicommunicating in the workplace is discussed, the theoretical and practical contributions of this research are described, and limitations and suggestions for future research are outlined.

The digital divide has loomed as a public policy issue for over a decade. Yet, a theoretical account for the effects of the digital divide is currently lacking. This study examines three levels of the digital divide. The digital access divide (the first-level digital divide) is the inequality of access to information technology (IT) in homes and schools. The digital capability divide (the second-level digital divide) is the inequality of the capability to exploit IT arising from the first-level digital divide and other contextual factors. The digital outcome divide (the third-level digital divide) is the inequality of outcomes (e.g., learning and productivity) of exploiting IT arising from the second-level digital divide and other contextual factors. Drawing on social cognitive theory and computer self-efficacy literature, we developed a model to show how the digital access divide affects the digital capability divide and the digital outcome divide among students. The digital access divide focuses on computer ownership and usage in homes and schools. The digital capability divide and the digital outcome divide focus on computer self-efficacy and learning outcomes, respectively. This model was tested using data collected from over 4,000 students in Singapore. The results generate insights into the relationships among the three levels of the digital divide and provide a theoretical account for the effects of the digital divide. While school computing environments help to increase computer self-efficacy for all students, these factors do not eliminate knowledge the gap between students with and without home computers. Implications for theory and practice are discussed.

We analyze a large-scale custom software effort, the Worm Community System (WCS), a collaborative system designed for a geographically dispersed community of geneticists. There were complex challenges in creating this infrastructural tool, ranging from simple lack of resources to complex organizational and intellectual communication failures and tradeoffs. Despite high user satisfaction with the system and interface, and extensive user needs assessment, feedback, and analysis, many users experienced difficulties in signing on and use. The study was conducted during a time of unprecedented growth in the Internet and its utilities (1991–1994), and many respondents turned to the World Wide Web for their information exchange. Using Bateson's model of levels of learning, we analyze the levels of infrastructural complexity involved in system access and designer-user communication. We analyze the connection between systems development aimed at supporting specific forms of collaborative knowledge work, local organizational transformation, and large-scale infrastructural change.

Internet-based interactive multimedia technologies enable online firms to employ a variety of formats to present and promote their products: They can use pictures, videos, and sounds to depict products, as well as give consumers the opportunity to try out products virtually. Despite the several previous endeavors that studied the effects of different product presentation formats, the functional mechanisms underlying these presentation methods have not been investigated in a comprehensive way. This paper investigates a model showing how these functional mechanisms (namely, vividness and interactivity) influence consumers' intentions to return to a website and their intentions to purchase products. A study conducted to test this model has largely confirmed our expectations: (1) both vividness and interactivity of product presentations are the primary design features that influence the efficacy of the presentations; (2) consumers' perceptions of the diagnosticity of websites, their perceptions of the compatibility between online shopping and physical shopping, and their shopping enjoyment derived from a particular online shopping experience jointly influence consumers' attitudes toward shopping at a website; and (3) both consumers' attitudes toward products and their attitudes toward shopping at a website contribute to their intentions to purchase the products displayed on the website.

The emergence of software-based platforms is shifting competition toward platform-centric ecosystems, although this phenomenon has not received much attention in information systems research. Our premise is that the coevolution of the design, governance, and environmental dynamics of such ecosystems influences how they evolve. We present a framework for understanding platform-based ecosystems and discuss five broad research questions that present significant research opportunities for contributing homegrown theory about their evolutionary dynamics to the information systems discipline and distinctive information technology-artifact-centric contributions to the strategy, economics, and software engineering reference disciplines.

User participation has long been considered a key ingredient in information system development (ISD). However, research has generally failed to clearly demonstrate the benefits of user participation. A better description of interpersonal processes which occur during system development could be used to help explain the weak results. The present study builds upon the work of Robey and his colleagues (Robey and Farrow 1982, Robey et al. 1989, Robey et al. 1993), who examined user participation, influence, conflict, and conflict resolution during ISD. Results obtained in a field study of 74 IS projects suggest the following four conclusions: (i) conflict is best represented and measured as a multidimensional construct; (ii) the relationship between user participation and conflict is more complex than previously believed; (iii) influence has a dual role in the emergence of conflict; and (iv) influence plays a key role in the satisfactory resolution of conflict.

In this research, a study of the effects of coordination mechanisms and risk drivers such as project uncertainty on the performance of software development projects was conducted. Two types of coordination mechanisms were considered: vertical and horizontal. The former refers to the extent to which coordination between users and IS staff is undertaken by authorized entities such as project managers or steering committees. The latter refers to the extent to which coordination is undertaken through mutual adjustments and communications between users and IS staff. A new research model was developed by synthesizing research using the structural contingency perspective from Organization Theory and the risk-based perspective in Software Engineering. The model suggests that residual performance risk, i.e., the difficulty in estimating performance-related outcomes during the later stages of the project, can clarify the relationship between project uncertainty, coordination mechanisms and performance. Eight hypotheses were derived from the model for empirical testing. Data were collected from 64 software development projects in the banking and other industries. The results provide considerable support for a revised research model. As expected, project uncertainty increases residual performance risk. Both in turn have a direct negative effect on performance. Vertical coordination significantly reduces both project uncertainty and residual performance risk. However, horizontal coordination does not have any significant effect on residual performance risk. Instead, it has a direct positive effect on project performance. Moreover, higher levels of both vertical and horizontal coordination lead to higher levels of overall performance. Their differential impacts on residual performance risk are interesting areas of future research.
