The realization of benefits from these investments de- pends on supporting effective use of information technology (IT) and satisfying IT users. User satisfaction with information systems is one of the most important determinants of the success of those systems. Drawing upon a sample of 407 end users of ERP systems and working within the framework of confirmatory factor analysis (CFA), this study examines the structure and dimensionality, and reliability and validity of the end-user computing satisfaction (EUCS) instrument posited by Doll and Torkzadeh (1988). In response to Klenke’s (1992) motion to cross-validate management information system (MIS) instruments and to retest the end user computing satisfaction instrument using new data, this study’s results, consistent with previous findings, confirm that the EUCS instru- ment maintains its psychometric stability when applied to users of enterprise resource planning application software. Implications of these results for practice and research are provided. Subject Areas: End-User Computing,
