A Theoretical and Empirical Validation of IS Success Models in a Temporal and Quasi Volitional Technology Usage Context

IS implementation success is a critical information systems research issue. This study further extends and assesses both empirically and theoretically prior research on information system (IS) success. Specifically, we examine DeLone and McLean’s (1992) seminal model of IS success, and its subsequent refinement by Seddon (1997), and Rai et al. (2002) in a temporal context through a longitudinal study. Our study evaluates the IS success model by examining quasi-volitional use of email to support work requirements. Structural equation modeling is used to analyze data collected from 216 employees of Chinese organizations on their email usage at two different points in time. Our findings are interpreted in the broader context of IS success including the Davis’ (1989) Technology Acceptance and Goodhue’s (1995) Task-Technology fit models. Our results provide a more comprehensive and in-depth understanding of IS management in a richer context and should help organizations prescribe better strategies in IS management.
