What does NIMS state about the flow of information during an incident?

The National Incident Management System (NIMS) emphasizes the importance of clear and effective communication during an incident. The flow of information both upward and downward through the command hierarchy ensures that all levels of the organization are informed and can make decisions based on accurate, timely data. This two-way communication is vital for coordinating efforts, enhancing situational awareness, and ensuring that resources are deployed effectively to address the incident.

Upward communication allows subordinate levels to provide feedback, share updates, and report on conditions, ensuring leadership is informed of the ground situation. Conversely, downward communication is critical for conveying decisions, strategies, and important information from leadership to operational personnel. This dynamic flow facilitates unified command and integrated response efforts, enhancing overall incident management.

In contrast, limiting information strictly to local agencies, prioritizing media over operational needs, or collecting information without dissemination contradicts the principles of NIMS, which promotes transparency, collaboration, and comprehensive situational awareness to ensure an effective response.
