Answer:
Control mechanisms.
Explanation:
Organization charts are tree-like structures, commonly detailed from the top-most job position to the lowest job position available. Seeing an organizational chart would allow you to recognize what positions are under the supervision of a higher job position, illustrating the formal structure of the organization at hand.
It is possible to have knowledge of reporting relationships from just seeing the organizational chart based on this display. You would also be able to have a general overview of the work division between each department by seeing the organization.
However, it is not possible to know which control mechanisms are used by each position to execute their management functions. Control mechanisms are, for example, budgets, reports, and performance reviews. This information is never displayed in an organizational chart.
