User acceptance of enterprise resource planning systems: a study in small and medium enterprises in Vietnam

Abstract

This study aims at investigating important antecedents affecting the user acceptance of enterprise resource planning (ERP) systems. The research model was developed based on the technology acceptance model (TAM). The model was empirically tested using data obtained from an online survey of ERP users in 63 small and medium-sized enterprises (SMEs) in Vietnam. A total of 416 responses were gathered in which 14 uncompleted questionnaires were removed, leaving 402 usable questionnaires. The results revealed that the proposed factors almost positively influenced the user attitude toward using ERP systems directly and indirectly through the two TAM beliefs, except the paths from management support to perceived ease of use and from technical complexity to perceived usefulness, while perceived usefulness together with user attitude, in turn, enhanced behavioural intention to use ERP systems. Additionally, income, employees' position, and work nature were found to have moderating effects in the conceptual framework.
