A Newtonian metaphor for describing the effect of a radical change sti
mulus on the productive ability of work groups is presented in this pa
per. The impact of a downsizing process on a Fortune 500 company was m
odeled in terms of its effect on employee perceptions of their work co
ntext and their capacity for doing productive work. Also investigated
was the extent to which downsizing led to entropy (disorder) or negent
ropy (order) as employees revised their work schemas. The results indi
cate that a mechanistic shift in information processing perceptions an
d a decline in capacity to maintain effective work behaviors occurred
as a result of the downsizing. An interesting finding was that the mag
nitude of this productivity decline depended only on the initial and t
erminal information processing perceptions of the managers and not the
ir intermediate perceptions, suggesting that the managers' perceptual
state demonstrated the open systems property of equifinality.
