Various approaches have been developed for the evaluation of information systems,
and each is characterized by its individual positive and negative features. While a
single measure of IS success or IS effectiveness would certainly be desirable, it seems
unlikely that such a measure could be found. Instead, research has provided
taxonomies of success variables, which can be applied in different situations (DeLone
and McLean, 1992; Grover et al., 1996). Generally, the success of an information system
can be evaluated through:
. the quality of information provided to users;
. the impact of IS on users’ thinking, decisions or actions; and
. the impact of IS on costs and benefits at an organizational level.
