Unity of command is a management principle that states each employee should report to only one supervisor. This structure helps to clarify roles and responsibilities, reducing confusion and conflict in decision-making. When everyone knows who to turn to for guidance, it streamlines communication and enhances accountability. In organizations, unity of command ensures that instructions and feedback come from a single source, which can improve efficiency. This principle is particularly important in emergency situations, such as in military operations or emergency response teams, where clear lines of authority can significantly impact outcomes.
