FACULTÉ & RECHERCHE

We consider recent research in IS, as well as recent advances in the fields of psychology and sociology. As an alternative to existing models, we propose a new strategic path to study IT use through users’ IT culture and IT needs. Our contributions are (1) theoretical: we investigate the predictive value for IT usage of several new constructs and show that both expectancy-based and needs-based theories of motivation should be taken into account in acceptance models, (2) methodological: we adopt an exploratory, mixed-method, grounded theory approach and use both quantitative and qualitative data and methods, an unusual approach in IS research that allows new perspectives, and (3) practical: our results highlight the fact that highly IT-acculturated users may hinder (rather than facilitate) new-IT acceptance if their situational IT needs are ignored. Therefore, when the strategic decision of implementing new IT is made, managerial attention must be focused on these users in order to drive toward the alignment of their IT needs and managerially-perceived organizational IT needs.
