[Integration is defined as] the process of achieving unity of effort among the various subsystems in the accomplishment of the organization's task. - Paul R. Lawrence

CONSIDERABLE attention has recently been devoted to understanding behavior in large organizational systems. Although some of this work has been based on research, it has more typically been general theorizing with little support from research data. Our interest in examining complex organizations is to study more systematically and empirically their internal functioning in relation to the demands of the external environment on the organization and the ability of the organization to cope effectively with these demands, contributing to a theory of the functioning of large organizations based on empirical research.

Other things being equal, differentiation and integration are essentially antagonistic, and that one can be obtained only at the expense of the other.

The act of segmenting the organization into departments would influence the behavior of organizational members in several ways. The members of each unit would become specialists in dealing with the particular tasks. Both because of their prior education and experience and because of the nature of their task, they would develop specialized working styles and mental processes.
