Extending the unified theory of acceptance and use of technology (UTAUT) model

Unified Theory of Acceptance and Use of Technology (UTAUT) Model helps understanding the drivers of acceptance of new information technologies by its users. The model theorizes that four constructs play a significant role as direct determinants of user acceptance and usage behaviour: performance expectancy, effort expectancy, social influence, and facilitating conditions. Even though several researchers discuss the relevance of culture in user acceptance of new technologies, the UTAUT model does not use culture as a direct determinant. This paper argues that culture is a direct determinant of behavioural intention. Three case organizations that are using Enterprise Resource Planning (ERP) systems in Sri Lanka have been revealed that “culturally based individual behaviour” also plays a significant role in accepting new information technologies such as ERP systems by users. Therefore, it is proposed to extend the UTAUT model by incorporating culture as the fifth construct of the model.
