This document discusses different perspectives on how organizational structures emerge and change over time. It describes the power-control view, which argues that structures are determined through political processes as those in power seek to maintain and enhance their control. Key points of the power-control model include that structural decisions are the result of divergent interests among decision-makers, and that contingency factors like technology and environment act as constraints rather than sole determinants of structure. The implications are that those in power will prefer structures with degrees of complexity, formalization, and centralization that maximize their control.
