Introduction The DeLone and McLean (D & M) Information Systems Success Model measures the complex dependent variable “IS Success” in IS research. This paper discusses the research contributions in “IS success” over the last decade, which propose enhancements to the D & M IS Success model. As a result of these propositions, refinements are made into the existing model so as to have an updated model for measuring e-commerce system success. Finally recommendations are made. Back Ground Information In 1992 a first paper was published in which an attempt was made to understand the independent variable “IS Success” in the IS research. It had been based on the findings by a number of researchers in the 1970s and 1980s. Over the period of ten years, its popularity grew which can be estimated by the citation of it in nearly 300 articles. Hence, this popularity of the model identified a need for integration of IS research findings. Over a 100 articles have been selected from various journals so as to update the model and evaluate its usefulness with the changes in IS practices over the 10 years while focusing mainly on the growth of e-commerce and its impact on the model. The Model Initially The initial purpose of the paper published in 1992 was to provide a base and guidance in “IS Success” to future researchers. This initial paper presented a multidimensional model of IS Success which was based on research of Shanon and Weaver (1949), Masons theory of influence (1978), and the MIS research studies (1981–87). Shanon and Weaver (1949) which forms the base of the model defines three levels of IS success, namely technical level of communication (accuracy of information produced), semantic level (conveying of the intended message) and the effectiveness level on receiver. These levels are covered in six interrelated categories of the D & M IS model as
