Résumé


Purpose: Nowadays, most companies invest in buying or developing an information system in order to facilitate and follow its work. But sometimes final users reject these tools and consequently it causes a waste of time and money for companies. This problem has attracted and continues to attract the attention of several researchers. The present work joins this perspective and seeks to identify the determinants of the adoption of an IS by the final users. To do this, we present a literature review about the evolution and limitations of the two theories of adoption: IDT (Innovation diffusion theory) and TAM (Technology acceptance model) and analyze the works related to these two theories in order to have a comparative analysis of the different versions of these theories and have an idea about the best theory and therefore knowing the factors that influence the adoption of IS.

Findings : The results of this systematic review show that the TAM theory remains the most used and the most practical theory that answer the question of the adoption of IS.

Research limitations: We can’t generalize the finding because even if the number of the documents studied is representative, it is still insufficient compared to the sample of published studies and we still need to do a statistical analysis to confirm the finding in order to have more accurate results.
