Answer:
Centralization.
Step-by-step explanation:
An organizational structure can be defined as the process which typically involves dividing an organization into various functional units.
Basically, the organizational structure comprises of three (3) main dimensions and these are;
I. The vertical dimension: this is typically the decision-making responsibilities (decentralization and centralization).
II. The horizontal dimension: this divides the organization into subunits.
III. Integrating mechanisms: it is based typically on the strategic mechanism that controls the various subunits within an organization.
In the vertical dimension of an organizational structure, centralization can be defined as a practice which includes giving only limited authority and decision-making to lower-level managers. Thus, most of the authority and power is concentrated at the top level.
