A network analytic approach to the study of organizational response to cris
es is used to determine the existence and form of integrated crisis managem
ent units (ICMUs). ICMUs are network organizations that emerge in response
to severe crises such as major oil spills, earthquakes, hurricanes and othe
r natural and man made disasters. Although ICMUs have received considerable
attention from scholars in the form of empirical case studies, much remain
s unclear as to their nascent interorganizational structure and structural
evolution. In this paper, we outline a network analytic framework for the s
tudy of ICMUs and demonstrate how some of the predictions of previous resea
rch can be more rigorously quantified and compared. We then apply our frame
work to the 1989 Exxon Valdez oil spill. The Valdez case study provides an
illustration of the analytic framework and suggests some interesting direct
ions for further research on emergent organizational forms. Results demonst
rate (1) the emergence of a network organization which grew more complex an
d more centralized over time, (2) the vulnerability of emergent structures
to after shocks, and (3) the structuration of the organizational field thro
ugh coordination of multiple network organizations, despite fluctuation in
peripheral groups of stakeholder organizations.
