That autonomy notwithstanding, divisionalization does not amount to decentralization, although the terms are often equated with each other. Deaentralizarion is an expression of the dispersal of decision-making power in an organization. Divisionalization refers to a structure of semi autonomous market-based units. A divisionalized structure in which the managers at the heads of these units retain the lion’s share of the power is far more centralized than many functional structures where large numbers of specialists get involved in the making of important decisions.
