This study investigates the phenomena of cultural orientation, such as power distance and collectivism, and personal innovativeness in IT (as stable individual differences)as well as general computer self-efficacy (as a dynamic individual difference) in the context of the technology acceptance model (TAM) forERP system adoption. One hundred and one survey questionnaire results of an international user group utilizing an ERP system developed by one of the largest IT solution providers in the world were analyzed using PLS. Power distance negatively affects computer self-efficacy and innovativeness positively affects computer self-efficacy, as expected. Computer self-efficacy and innovativeness affect ease of use, while collectivism affects usefulness.Theoretical and practical implications of these findings for global IT management are discussed.
