Fan Zhao, Dallis Schaefer, Aden Katz, Henderson De Leon

Abstract
More and more companies are updating their current ERP systems now. With previous implementation experience, organizations tended to pay less attention to the upgrade projects. This could increase their failure rate and reduce the productivity of the systems. In this mixed-method study, we conducted both qualitative and quantitative research to explore hidden patterns from several large organizations that switched ERP vendors when they upgradedERP systems. We analyzed the reasons for switching vendorsand identified constructs influencing the decision-making of ERP upgrade package selection.We further studied the impact of UI/UX of ERP systems on operational performance from the end-users perspective. Combining the qualitative and quantitative studies results, we discussed key factors that top management concerned when they started ERP upgrade projects. These results supported our hypothesis that an ERP system with better UI/UX would improve user performance and further impact the adoption decisions for ERP upgrade projects.
