Hierarchical structures are organizational frameworks where elements are ranked according to levels of authority or importance. In such systems, each level has a specific role, with higher levels exerting more control over lower ones. This structure is commonly seen in businesses, governments, and educational institutions, where clear lines of command and responsibility are established. In a hierarchical structure, communication typically flows from the top down, meaning decisions are made by higher-ups and passed down to subordinates. This can lead to efficient decision-making but may also result in slower responses to changes, as lower levels may have limited input. Examples include corporate organizations, military organizations, and school administrations.
