Information systems success model

Initial development of the theory was undertaken by William H. DeLone and Ephraim R. McLean in 1992,[1] and was further refined by the original authors a decade later in response to feedback received from other scholars working in the area.

[2][3] The IS success model has been cited in thousands of scientific papers, and is considered to be one of the most influential theories in contemporary information systems research.

The IS success model identifies and describes the relationships among six critical dimensions of IS success: information quality, system quality, service quality, system use/usage intentions, user satisfaction, and net system benefits.

System quality indirectly impacts the extent to which the system is able to deliver benefits by means of mediational relationships through the usage intentions and user satisfaction constructs.

Service quality directly impacts usage intentions and user satisfaction with the system, which, in turn, impact the net benefits produced by the system.
