Final answer:
The hierarchical structure uses a single directional flow of authority in a company.
Step-by-step explanation:
The organizational structure that uses a single directional flow of authority in a company is hierarchical structure.
In this type of structure, authority and decision-making flow from top to bottom in a pyramid-like fashion.
Each employee reports to a supervisor or manager, who in turn reports to a higher-level manager, and so on.
For example, in a hierarchical structure, a CEO would hold the highest level of authority and make decisions that trickle down through different layers of management to frontline employees.
This structure ensures clear lines of authority and promotes accountability, but it can lead to slower communication and decision-making.
It is commonly found in large corporations or organizations with strict reporting and accountability processes.
