This article reports on the findings of a wide-ranging study designed
to 'benchmark' the system dynamics community. The study captured infor
mation about individual practitioners across a number of dimensions, i
ncluding background, approach to and practice of model building, use o
f hardware and software and knowledge of the history and development o
f the field. Circulated to all members of the System Dynamics Society,
the study attracted responses from 163 members (over 35 percent). The
following pages present research results and discuss their possible i
mplications, In particular, important conclusions highlight a potentia
l quality gap in the model base, postulate a relationship between peda
gogy and practice and begin a dialog concerning the dynamics of supply
and demand in the field.
