What is NOT an activity of an incident command system?

The reason conducting research studies is not an activity of an incident command system is that the primary focus of such a system is on managing and coordinating emergency responses rather than performing research functions. Incident command systems are designed to ensure effective communication, resource allocation, and operational coordination during emergencies, making rapid diagnostic reporting, public awareness campaigns, and implementing quarantine and movement controls integral activities. Research studies, while important in the broader context of understanding and managing incidents over the long term, do not fit within the immediate operational framework of an incident command structure, which prioritizes action and resolution in real-time situations.
