Which principle emphasizes the need for unity in command?

The principle that emphasizes the need for unity in command is unity of command. This principle asserts that each employee should receive orders from only one superior to avoid confusion and potential conflict in instructions. When there is unity of command, it ensures that all employees understand the chain of command, which helps maintain order and accountability within an organization.

In practice, this principle is critical because it enables efficient decision-making and clear communication. When individuals report to multiple leaders, it can lead to mixed signals and contradicting tasks. Unity of command thus aims to streamline the organizational structure, enhance operational efficiency, and establish a definitive line of authority, which is essential in any public works context where coordination among various teams is vital.

Other principles, while important, do not specifically address the necessity of having a single point of command for each employee, which is the hallmark of unity of command.
