An investigation into the effects of IS quality and top management support on ERP system usage

Enterprise resource planning (ERP) systems are developed to manage and integrate business processes across organisational functions and locations. Given the growing importance of ERP deployment, a better understanding of influences on successful ERP system implementation is essential for knowledge advancement. Based on previous IS success literature, this study develops an empirical model to examine the effects of IS quality (information and system quality) and top management support on ERP system usage. The proposed model was tested using survey data from large Taiwanese corporations. The results show that information and system quality directly or indirectly affect ERP system usage through user perceptions of usefulness and satisfaction with the ERP system. Additionally, top management support influences both perceived usefulness and ERP system usage. Results of this study contribute to efforts to identify the factors that measure ERP system success. The implications for theory and practice and future research directions are discussed.
