This paper examines the impact of knowledge transfer in organizational rest
ructuring using a computer simulation model. The study demonstrates that th
e direction of the change, the nature of the external environment, and the
learning mechanism can ail influence how knowledge transfer affects organiz
ational performance. Specifically, the study shows that organizations may s
uffer the most performance degradation through a vertical structural change
. It also reveals that expansions tend to cause a greater impact on organiz
ational performance while downsizings in an unpredictable environment can a
lso be highly risky. The study further indicates that learning can be a ver
y effective mechanism for rebuilding organizational knowledge and buffering
the negative effect of organizational expansions, though its benefit may b
e limited under a predictable environment or in organizational downsizings.
