Which of the following lists are basic principles of organization?

• A. Unity of Command, Span of Control, Division of Labor, and Command Tactics
• B. Unity of Command, Span of Control, and Employee Assistance Program
• C. Unity of Command, Span of Control, Human Resources, and Legal Process
• D. Unity of Command, Span of Control, and Division of Labor

Answer: (D)

The main concept is how to structure a fire department or incident organization so authority is clear and work gets done efficiently. The best list includes Unity of Command, Span of Control, and Division of Labor. Unity of Command means each person reports to one supervisor, preventing conflicting instructions and confusion on the scene. Span of Control refers to how many direct reports a supervisor can effectively manage; keeping this number appropriate helps maintain clear supervision, fast communication, and quick decision-making. Division of Labor is about assigning specialized tasks to people or units, which increases efficiency and helps people focus on specific responsibilities such as operations, logistics, or planning.

Why this set is best: it covers the core ways to structure authority and workload in an organization, which directly impact how smoothly operations run during an incident.

The other options mix in programs or functions (like Employee Assistance Program or Human Resources) or concepts that aren’t basic organizing principles (such as Legal Process or Command Tactics). Those are important in a broader organizational context, but they aren’t core principles of how to structure an organization itself.
