STRUCTURE IN 5'S: A SYNTHESIS OF THE RESEARCH ON ORGANIZATION DESIGN* HENRY MINTZBERGt
The elements of organizational structuring-which show a curious tendency to appear in five's-suggest a typology of five basic configurations: Simple Structure, Machine Bureaucracy, Professional Bureaucracy, Divisionalized Form, and Adhocracy. The elements include (1) five basic parts of the organization-the operating core, strategic apex, middle line, technostructure, and support staff; (2) five basic mechanisms of coordination-mutual adjustment, direct supervision, and the standardization of work processes, outputs, and skills; (3) the design parameters-job specialization, behavior formalization, training and indoctrination, unit grouping, unit size, action planning and performance control systems, liaison devices (such as integrating managers, teams, task forces, and matrix structure), vertical decentralization (delegation to line managers), and horizontal decentralization (power sharing by nonmanagers); and (4) the contingency factors-age and size, technical system, environment, and power. Each of the five configurations relies on one of the five coordinating mechanism and tends to favor one of the five parts. In Simple Structure, the key part is the strategic apex, which coordinates by direct supervision; the structure is minimally elaborated and highly centralized; it is associated with simple, dynamic environments and strong leaders, and tends to be found in smaller, younger organizations or those facing severe crises. The Machine Bureaucracy coordinates primarily by the imposition of work standards from the technostructure; jobs are-highly specialized and formalized, units functional and very large (at the operating level), power centralized vertically at the strategic apex with limited horizontal decentralization to the technostructure; this structure tends to be found in simple, stable environments, and is often associated with older, larger organizations, sometimes externally controlled, and mass production technical systems. The Professional Bureaucracy relies on the standardization of skills in its operating core for coordination; jobs are highly specialized but minimally formalized, training is extensive and grouping is on a concurrent functional and market basis, with large sized operating units, and decentralization is extensive in both the vertical and horizontal dimensions; this...
