What kind of organizational structure does the following belong to? Linear system? Functional system? Linear function system? Or something else?

The figure shows a linear functional system.

Linear functional organizational structure is the most widely used organizational form in reality. It combines the linear structure with the functional structure, as the leader's staff, and implements the organizational structure form of unified command of the supervisor and staff and guidance of functional departments.

Linear functional system is the combination of linear system and functional system. It is not only a straight-line department to ensure the realization of organizational goals, but also a functional department set up according to professional division of labor; However, the function of the functional departments here is to be the staff and assistant of the line leaders at the same level, and cannot give orders to the lower departments. This organizational structure absorbs the advantages of linear system and functional system: on the one hand, administrative leaders at all levels have corresponding staff offices as assistants to give full play to their professional management role; On the other hand, each level of management has maintained a centralized and unified command. However, in practical work, the straight-line function system often places too much emphasis on straight-line command and pays insufficient attention to the staff's authority.
