"Most of our beliefs about complex organizations follow from one or the other of two distinct strategies. The closed-system strategy seeks certainty by incorporating only those variables positively associated with goal achievement and subjecting them to a monolithic control network. The open-system strategy shifts attention from goal achievement to survival and incorporates uncertainty by recognizing organizational interdependence with environment. A newer tradition enables us to conceive of the organization as an open system, indeterminate and faced with uncertainty, but subject to criteria of rationality and hence needing certainty."

“Organizations under norms of rationality seek to place their boundaries around those activities which if left to the task environment would be crucial contingencies.”

“When buffering, leveling, and forecasting do not protect their technical cores from environmental fluctuations, organizations under norms of rationality resort to rationing.”

“If we now reintroduce the conception of the complex organization as an open system subject to criteria of rationality, we are in a position to speculate about some dynamic properties of organizations.”

“Under norms of rationality, organizations seek to smooth out input and output transactions.”

“A central purpose of this book is to identify a framework which might link at important points several of the now independent approaches to the understanding of complex organizations.”

“The more sectors in which the organization subject to rationality norms is constrained; the more power the organization will seek over remaining sectors of its task environment... many constraints and unable to achieve power in other sectors of its task environment will seek to enlarge the task environment.”
