The physical sciences have developed new theories of nonlinear behavior of
complex systems. Defining characteristics of complex systems include (a) be
ing composed of many variables that interact strongly to determine system b
ehavior (b) sensitivity to initial conditions, and (c) stability across tim
e. Two complex-systems concepts, phase spaces and attractors, provide insig
ht into the evolution of system behavior and make prediction of future beha
vior possible. It is proposed that complex-systems research has application
to the study of organizations and social behavior. Organizational attracto
rs exist and seem to be both sensitive to initial conditions and stable. Th
e discussion of concepts from complex systems, and their application to org
anizations, provides insight into how organizational research should be con
ducted. If organizations are assumed to exhibit nonlinear behavior, more hi
storical, longitudinal, and qualitative research methods should be used to
provide context-specific descriptions of organizational behavior.
