As a powerful communications and commerce medium, the Internet is a communication
and IS phenomenon that lends itself to a measurement framework (i.e., the
D&M IS Success Model) that is built on communication theory (e.g., Shannon and
Weaver [43]). Within the e-commerce context, the primary system users are customers
or suppliers rather than internal users. Customers and suppliers use the system to
make buying or selling decisions and execute business transactions. These electronic
decisions and transactions will then impact individual users, organizations, industries,
and even national economies. This communications and commerce process fits
nicely into the updated D&M IS Success Model and its six success dimensions.
