7.8 Conclusions

Research on IS success measurement is a vast body of knowledge without a single
methodology or framework that can be universally applied.
DeLone and McLean outlined a model that relied primarily on the concept of a
process of causal relationships, comprised of three major key aspects: quality, use,
and impact. Their seminal work, which was far from de ning a complete and

comprehensive model for future studies, merely opened the door for progress on
that

field, and there have been numerous attempts to improve that model, or to
create a new one.
The Seddon s model worked on the D&M concept even further and defended the

notion that the behavioral aspect of IS use must be emphasized as it fundamentally
alters the simple causal processes described by D&M. It also brought attention to
the need to further examine the concept of impact, which D&M had outlined as a
simple dual concept of organizational and individual impact. Seddon introduced the
concepts of net bene

'

ts and expectations as part of the success cycle.
The 3D model attempted to shift the focus of research toward the process of IS
development and implementation, arguing that it is along this process that measures
for success can be identi

ed, implemented, and used in an ongoing learning cycle.
The IS-impact measurement model went back to the D&M approach and again
emphasized a duality of quality and impact as key factors of success, but built a
more fluid, dynamic correlation between those factors.

Generically, we can see that researchers have all agreed in that IS success cannot
be estimated with accurate precision because it relies on multiple variables, some
external to the system, other endogenous to it. The degree of importance attributed
to these variables can differ greatly from study to study; however, some factors have
been recurrently used, such as usage and user satisfaction. However, different
studies will insert these factors within different processes and/or cycles.
Ultimately, IS success measurement research is a

field that will, most likely,
continuously grow and evolve as IT and IS itself evolves, because it is a funda-
mental and necessary aspect of modern organizational management in a techno-
logically driven, globalized world.
