Zusammenfassung
The evaluation of the performance of information technology and information systems has, over the past three decades, been the object of numerous studies using a wide range of models. Few of them have focused on the study of efficiency, and even fewer still on the development of a specific research model. This paper helps to fill this gap by making a contribution towards formalizing a specific, original theoretical framework and conceptual model, one based on user confidence in ad hoc EDI technology and the risks associated with its use. The model is tested using data obtained from users of a value added network in the car insurance sector. The results of the data analysis, obtained through a series of principal component analysis methods with a Promax rotation and an Amos structural equation analysis, confirm the existence, on the one hand, of an optimal structure of EDI efficiency evaluation factors, and on the other hand, of the relevance of a data model that establishes a hierarchy aimed at explaining risk.
