This approach is most common in the form of departmentalization. Functional departmentalization groups together jobs which are involving the same or similar activities.
Here; the word function is used to mean organizational functions such as finance and production, rather than the basic managerial functions, such as planning or controlling. Noted economist Oliver E. Williamson termed it as the ‘U- form’ (for unitary) design.
Functional departmentalization allows the organization to staff all important positions with functional experts and facilitates coordination and integration.
However; it also promotes tends to promote centralization. For the organization to operate efficiently in this design there must be considerable coordination across departments.

As mentioned, this is perhaps the most common form of departmentalization. The image shows that marketing, production, engineering, and finance are the four most common functions in most organizations.
‘Personnel’ is another major function in any organization and encompasses recruitment, selection, training, compensation, health and safety, and labor relations.
