Abstract

This study investigates the process of acceptance and use of Enterprise Resource Planning (ERP) systems by its users, in order to understand the reasons behind their behavior. The Technology Acceptance Model (TAM) is used as a starting point for this work. In accordance with the TAM, two user’s beliefs, perceived usefulness and perceived ease of use, affect the behavioral intention to use a specific technology. Moreover, perceived ease of use also influences perceived usefulness. In literature, there are few prior research that focused on role of affective commitment in determining the process of acceptance and use of technology. These have shown that affective commitment positively affects the TAM constructs such as perceived usefulness and perceived ease of use. Unlike these prior research, we assume that affective commitment directly also affects both the behavioral intention to ERP system use and it moderates the relationships between perceived usefulness, perceived ease of use, and behavioral intention. A survey methodology was used to gather data from an Italian public transport firm. Findings show the importance of affective commitment in determining acceptance and use behavior by users. In particular, our results highlight that affective commitment does not moderate the relationships between perceived usefulness, perceived ease of use, and behavioral intention. Moreover, results shown that affective commitment affects behavioural intention to IT use trough user’s beliefs and, above all, it directly and positively affects behavioural intention. We discuss the implications of these results for theory and practice.
