Within the National Incident Management System Characteristics, the concept of common terminology covers all of the following (Resource Descriptions, Organizational Functions, and Incident Facilities) EXCEPT Technical Specifications.

As per the FEMA IS-100.C Instructor Guide, common terminology in NIMS includes:

• “Organizational Functions: Major functions and functional units with incident management responsibilities are named and defined. They remain standard and consistent.
• Resource Descriptions: Major resources – including personnel, equipment, teams, and facilities – are given common names and are ‘typed’ with respect to their capabilities.
• Incident Facilities: Common terminology is used to designate the facilities in the vicinity of the incident area.”

However, common terminology does not extend to technical specifications. For example, while the terms used to describe resources or organizational functions would be standardized, the technical specifications of a particular piece of equipment would not be part of this common terminology.
