Introduction
The measurement of information systems
success or effectiveness is critical to our
understanding of the value and efficacy of IS
management actions and IS investments. In
1992, we published a paper (DeLone & McLean
1992) in which we attempted to bring some
awareness and structure to the “dependent
variable” – information systems success – in IS
research. We proposed a taxonomy and an
interactive model as frameworks for con-
ceptualizing and operationalizing IS success,
hereafter referred to as the D&M IS Success
Model. Since then, over 150 articles in refereed
journals and conference proceedings have
referred to, and made use of, this IS Success
Model. Five of the nine articles in Garrity &
Sanders’ 1998 book, Information System Success
Measurement,focus explicitly on issues related
to the D&M IS Success Model. The IS success
section of the ISWorld Web site is currently
organized according to the D&M success
taxonomy. The wide popularity of the model is
strong evidence of the need for a comprehensive
framework for integrating IS research findings.
The D&M IS Success Model, though
published in 1992, was based on theoretical and
empirical IS research conducted by a number of
researchers in the 1970s and 1980s. The role of
information systems has changed and progressed
during the last decade. Similarly, academic
inquiry into the measurement of IS effectiveness
has progressed over the same period. The
purpose of this paper therefore is to revisit,
reexamine, and reformulate the D&M IS Success
Model and IS measurement practice in light of
this rich body of recently published research.
