Which of the following is an ICS concept states that personnel report to only one supervisor and maintain formal communication relationships only with that supervisor?

The Incident Command System (ICS) concept that states personnel report to only one supervisor and maintain formal communication relationships only with that supervisor is known as “Unity of Command.”

Unity of Command helps to ensure that clear reporting relationships exist and eliminate the confusion caused by multiple, conflicting directives, maintaining systematic, orderly, and efficient command and control structures within an incident management effort, facilitating effective leadership and decision-making.

From the perspectives of emergency management personnel, Unity of Command is valued for its role in clarifying communication paths and simplifying the incident command structure, thereby enhancing operational efficiency and accountability.

Unity of Command also ensures that information flow remains streamlined and efficient throughout the incident’s duration, preventing the spread of inaccurate or conflicting information that could hamper response efforts.
