Name the type of organisational structure' which promotes efficiency in utilisation of manpower.

Explanation

The organisational structure which promotes efficiency of manpower is ‘Functional Structure’.

Note on Functional Structure:

A functional organization is a common type of organizational structure in which the organization is divided into smaller groups based on specialized functional areas, such as IT, finance, or marketing.

Functional departmentalization arguably allows for greater operational efficiency because employees with shared skills and knowledge are grouped together by function.
A disadvantage of this type of structure is that the different functional groups may not communicate with one another, potentially decreasing flexibility and innovation. A recent trend aimed at combating this disadvantage is the use of teams that cross traditional departmental lines.
