Command hierarchy refers to the structured arrangement of authority and responsibility within an organization. It outlines who reports to whom, ensuring clear lines of communication and decision-making. This structure is commonly seen in military organizations, corporations, and government agencies, where roles are defined to maintain order and efficiency. In a command hierarchy, individuals are typically organized in levels, with higher levels holding more authority. For example, a CEO leads a company, followed by managers who oversee specific departments, and employees who carry out day-to-day tasks. This system helps streamline operations and clarify roles within the organization.
