Managing culture creep: Toward a strategic model of user IT culture

This article describes a framework of IT user culture that has implications for organizational IT strategy. The research was conducted in multiple settings with a grounded theory approach. The resulting framework is anchored to nine archetypal IT user profiles and encompasses their inter-group dynamics. By adopting a cultural perspective on IT usage, the framework can inform IT adoption and usage strategy with possible cultural antecedents and determinants of usage constructs common in IS research. The proposed framework suggests how management can influence the migration of IT user culture (culture creep). This framework can also enrich other acceptance models in order to more fully consider the human factor during IT implementation and adoption. The results underscore the importance of culture-customizing organizational IT socialization, training and evolution programs.

Survey of Strategic Alignment Impacts on Organizational Performance in International European Companies

The strategic use of technology based information systems (IS/IT) is a fundamental issue for every business. This is particularly true in the case of firms that engage in international business activities. The present paper is part of an empirically oriented project to investigate the impacts of strategic alignment on organizational performance, especially in the case of European International Companies. We use Structural Equation Modeling to apprehend the strategic alignment concept as an emergent variable derived from the co variation of two components: (1) business strategy; and (2) the IS/IT strategy. Then, we explore the role of this emergent concept as a determinant of organizational performance. We use data from a large database constructed due to survey instruments to assess the usage of IS/IT among European firms. 505 questionnaires have been exploited in this study. The results obtained will be presented and discussed in this paper.

The role of technologies in cultural mediation in museums: an Actor-Network Theory view applied in France

Abstract This paper examines how museum professionals perceive the role played by Information and Communication Technology (ICT) in their institutions. We conceptualise the interaction between museum professionals, works of art, the public and ICT in terms of a mediation process, which we define and discuss from an Actor-Network Theory (ANT) perspective. Using a qualitative research approach, we examine the different components of this process within four major museums in France. Our results indicate that two kinds of ICT-supported mediation types emerge: visitor-oriented (entertaining and customised) and curator-oriented (scientific and content-driven), and that the pre-supposed positive impact of ICT on the professional practices of museums seems controversial.

Measuring data warehousing success: an empirical investigation applying the DeLone and McLean model

The purpose of this study is to examine the factors that affect data warehousing success. The DeLone and McLean (1992) original model has been used as a backbone to construct an evaluation instrument which has been operationalised using data warehousing and IS success literature review and an exploratory case study conducted in a large European financial company. Two contextual variables: user participation and user involvement are introduced in the model and their roles on individual impacts of the data warehouse are tested. Our results confirm the determining power of information quality and user satisfaction as antecedents to the system use. Concerning the roles played by the contextual factors, only the direct effect of user involvement on individual impacts is supported.

Social Networking Continuance: When Habit Leads to Information Overload

In this paper, we propose an explanatory model of the continuance intention to use social networking sites (SNS). Our aim is to extend the post adoptive model by incorporating Habit and Information Overload as antecedents to SNS continuance intention. A quantitative approach based on an online survey administered to 320 executive managers in France confirms the positive role of habit in generating information overload and in positively affecting SNS continuance intention. The results also show that satisfaction and perceived usefulness do not seem to play any significant role.

Using a Systems Thinking Perspective to Construct and Apply an Evaluation Approach of Technology-Based Information Systems

In this article, we use soft systems methodology and complexity modeling to build an evaluation approach of a data warehouse implemented in a leading European financial institution. This approach consists in building a theoretical model to be used as a purposeful observation lens, producing a clear picture of the problematic situation under study and aimed at providing knowledge to prescribe corrective actions.
