 Information systems success model

The information systems success model (alternatively "IS success model" or "Delone and McLean IS success model") is an information systems (IS) theory which seeks to provide a comprehensive understanding of IS success by identifying, describing, and explaining the relationships among six of the most critical dimensions of success along which information systems are commonly evaluated.Initial development of the theory was undertaken by William H. DeLone and Ephraim R. McLean in 1992, and was further refined by the original authors a decade later in response to feedback received from other scholars working in the area.
