This research seeks to validate a comprehensive model of quality in the context of e-business systems. It also extends the UTAUT model with e-quality, trust, and satisfaction constructs. The proposed model brings together extant research on systems and data quality, trust, and satisfaction and provides an important cluster of antecedents to eventual technology acceptance via constructs of behavioral intention to use and actual system usage.
