A hierarchical structure is an organizational framework where elements are ranked according to levels of authority or importance. In this system, each level has specific roles and responsibilities, creating a clear chain of command. For example, in a company, the CEO is at the top, followed by managers, and then employees. This structure helps streamline decision-making and communication, as information flows from the top down. It also clarifies reporting relationships, making it easier to understand who is responsible for what. Hierarchical structures are commonly found in various organizations, including governments, schools, and military organizations.
