Information Systems’ Models for Success Assessment - High Level Models and Methodologies for Information Systems - page 121

Third, the multiplicity of success measures should be reduced to a minimum to
increase the possibilities of comparing studies and enhance the opportunity to validate
them.
Fourth, the organizational impact criteria for IS success assessment are under-
valued and under-researched.
And fifth, there is evident need for improvement of the original D&M model

(Delone 2003 ).
The research work that originated the D&M IS success model reviewed 180
studies concerning IS success measurement. In this review, the diversity of IS
success markers became clear. The six categories proposed in the paper served as a
classi cation criteria for all the IS success methods in the 180 studies. Hence, the

authors found that some studies concentrated their efforts in system quality, by
exploring the features of the IS that were required to guarantee its quality. The focus
of some of the studies was placed in the information quality, in criteria such as
timeliness and accuracy. An approach that also became evident was that of the
systems interaction with their users. In this case, the emphasis was directed at the

use of the system and the satisfaction of its users. The

'

final views of IS success
assessment concern the impact that the system has at an individual level, in man-
agement decision making and at an organizational level, in the performance of the
organization itself (DeLone and McLean 1992 ). One of the conclusions of the
D&M model was the lack of research on measures that contemplated the impact of
IS on an organizational level (DeLone and McLean 2002 ).
One of the most important aspects of the D&M model is the fact that it provided
a taxonomy to categorize the wide variety of criteria used in IS success assessment.
It organized the different measures into a framework of six dimensions. Also, while
outlining this framework, the model established a

relation
between its several measures (Seddon 1997 ). Although the dimensions of success
and their metrics should be adjusted to speci

“ temporal and causal ”

c objectives and contexts, it is
important to choose measures that have been tested and validated (DeLone and
McLean 2002 ).
The D&M model provides a framework for the assessment of IS success both at
the individual and organizational levels. Nonetheless, when moving past utilitarian
IS, this model has yet to prove its adequacy regarding IS that are related to
enjoyment and leisure. The dimensions that are used in this model to measure IS
success have not yet prove their pertinence in terms of social networking, gaming
environments, or any other IS that was designed for entertainment, in general. In
order to extend this model to this type of IS, it may be necessary to review some of
its criteria (Petter et al. 2008 ).
When outlining the D&M model, the authors made clear that the model was a
work in progress that further research and validation was required (DeLone and
McLean 2002 ).
