Network effects in technology acceptance: Laboratory experimental evidence
No full textThis research analyzes network effects in technology acceptance. The hypothesis is that the size of the user network affects technology acceptance. Even today, empirical measurement of network effects is challenging and there is a lack of experimental evidence. In order to investigate and measure the relation- ship between network size (number of adopters) and user acceptance, technology acceptance research needs to broaden its scope and approaches. To overcome this limitation we reproduce a particular type of technology acceptance process in a laboratory experiment, controlling for user network size and testing its influence on user perceptions and, ultimately, on acceptance decisions. We measured user perceptions and analyzed the data using consolidated and tested technology acceptance models. The results confirm our hypothesis, showing a significant effect of user network size on user perceptions. Finally, we discuss the theoretical and managerial implications of our approach and findings

Network outcome as trigger for the evolution of a collaborative design network: coordination processes between actors and objects
No full textAre Design Networks shaped by their own outcomes? Coordination processes between actors and artefacts
No full textThis paper sets the basis for a research project focused on collaborative social network’s genesis and
dynamics. It introduces a research framework for the empirical investigation of a network focused on
the design of a shared artefact, the so-called "Web services Architecture". Our hypothesis is that
network artefact’s characteristics, seen as the final outcome of a collaborative process, influence and
drive the genesis and the structure of the social network that is designing it. We embraced this view in
order to avoid a limitation of the traditional perspectives that consider the network structure as
exogenous and stable. We consider the reciprocal influence between the artefact and the social network
structure, with a phase in which the desired artefact may shape the network genesis and a phase in
which the emergent network’s structure may drive the artefact design

The enabling role of Web services in information system development practices : a grounded theory study
No full textThis study presents a grounded theory analysis of a case study in the banking industry with a view to showing the enabling role of “Web services” technology in information system development practices. The grounded theory analysis of the Cashier Management System development project at the Central Europe Bank (a pseudonym) shows that Web services technology is a key technological enabler for more agile forms of IS development, characterized by incremental analysis, requirements revision, requirements emerging in use and incremental implementation. In particular, an initial in-depth analysis phase, conducted in a traditional way, is then followed, during system development, by several iterative phases of requirements revision/addition, in fulfilment of emerging or previously unplanned user needs discovered along the way. Such system development practices, enabled by the Web services technology and influenced by a variety of contextual factors, cover a middle ground between methodical and amethodical development processe
Network effects in Technology Acceptance - Laboratory Evidence, International Conference of Information Systems
No full textThis research analyzes network effects in technology acceptance, on the hypothesis that the larger
is user network, the more likely is technology acceptance. Still today, empirical measurement of
network effects is challenging and there is a lack of experimental evidence, particularly in
technology acceptance research. To overcome this limitation we reproduce a particular class of
technology acceptance processes in a laboratory experiment, controlling for the user network size
to verify if it can make a difference in user perceptions and, ultimately, in acceptance decisions.
We measured user perceptions and analyzed the data set using standard technology acceptance
models. The experiments confirm our working hypothesis, showing a significant role of network
effects on key user perceptions influencing technology acceptanc

No full textValue generation in e-government from service-based IT integration
No full textUnderstanding how value is actually generated in e-government projects is one of the most challenging, and relevant, issues in e-government research. This paper aims to investigate the contribution of service-based information technology (IT) integration for generating value in the public sector, proposing a theoretical framework based on the theory of IT conversion effectiveness. The paper illustrates this novel approach to electronic government evaluation with an exploratory case study of a service-based IT integration project developed by the City of Genoa, showing how and why IT integration can substantially contribute to value generation in the public sector. Contrarily to what one would expect according to the original theory of IT conversion effectiveness, value generation may happen even with no substantial growth in the pre-existing IT asset portfolio. In fact, what is truly important is not only the availability of IT assets (policy output), but also their proper use (policy outcome) and their final effects on policy takers (policy impact). The case study shows how a low-cost and small IT integration project based on agile information system development practices can significantly leverage the legacy systems, enhancing the overall degree of IT conversion effectiveness (first stage), with expected positive effects on policy outcomes (second stage) and policy impacts (third stage). The enabling effect of the web services technology has a central role in the overall value generation process. While addressing a literature void in the context of public sector, this theoretical approach is substantial as it can be used to evaluate and maximize the value generated by e-government projects, with a special focus on service-based IT integration project
