to ensure efficient, clear, communication, the national incident management system characteristics recommend the use

The National Incident Management System (NIMS) characteristics recommend the use of common terminology (and, more broadly, plain language and integrated communications) to ensure efficient, clear communication.

Direct answer

In NIMS multiple-choice format, the specific correct choice for
“to ensure efficient, clear, communication, the National Incident Management System characteristics recommend the use” is:

• Common terminology.

NIMS training materials explain that using standard or common terminology is essential for clear, efficient communications among incident personnel, especially in multi‑agency or multi‑jurisdiction incidents.

Why common terminology matters

• It avoids confusion from agency‑specific codes, jargon, or 10‑codes, which other organizations may not understand.

• It supports a shared operating picture so responders from different disciplines can quickly coordinate actions.

• It fits within the broader NIMS communications concepts of plain language and integrated communications systems (shared plans, interoperable radios, data links).

Related NIMS communication characteristics

When this topic appears in NIMS/ICS courses (like IS‑100 and IS‑700), it is often paired with:

• Plain language / clear text – speak in everyday terms rather than codes or heavy technical jargon during joint operations.

• Integrated communications – common communications plans, interoperable systems, and agreed‑upon protocols to link all incident personnel.

So if you are answering a test-style question, choose “common terminology” as the recommended practice to ensure efficient, clear communication under NIMS.
