ABSTRACT: Ten years ago, we presented the DeLone and McLean Information Systems
(IS) Success Model as a framework and model for measuring the complexdependent
variable in IS research. In this paper, we discuss many of the important IS
success research contributions of the last decade, focusing especially on research
efforts that apply, validate, challenge, and propose enhancements to our original model.
Based on our evaluation of those contributions, we propose minor refinements to the
model and propose an updated DeLone and McLean IS Success Model. We discuss
the utility of the updated model for measuring e-commerce system success. Finally,
we make a series of recommendations regarding current and future measurement of
IS success.
