The relation of interface usability characteristics, perceived usefulness, and perceived ease of use to end-user satisfaction with enterprise resource planning (ERP) systems

Over the past few years, firms around the world have implemented enterprise resource planning (ERP) systems to have a standardized information system (IS) in their respective organizations and to reengineer their business processes. While millions of dollars have been spent on implementing ERP systems, previous research indicates that potential users may still not use them. This study, based on data from 51 end-users in 24 companies examines various usability factors affecting end-user satisfaction with ERP systems. The results indicate that both perceived usefulness and learnability are determinants of end-user satisfaction with ERP systems. In addition perceived ease of use and system capability affect perceived usefulness, while user guidance influences both perceived usefulness and learnability. Implications of these findings are discussed and further research opportunities described.
