Which of the following describes a tiered hierarchical structure?

A tiered hierarchical structure is characterized by having multiple levels of authority within an organization. This type of structure typically features a clear chain of command, where decisions are made at higher levels and responsibilities are delegated down through the hierarchy. Each level has defined roles and responsibilities, contributing to the overall functioning of the organization.

In this structure, the presence of more levels of authority allows for a more organized approach to management and can facilitate specialization, as different levels can focus on particular functions and decision-making processes.

The other options illustrate different organizational structures, such as having only one level of authority or promoting a flatter management style, which does not align with the concept of a tiered hierarchy. Additionally, direct communication channels suggest a more streamlined approach, often found in less hierarchical structures where information flows freely with less reliance on formal levels of authority.
