What concept facilitates interoperability among organizations in incident response according to NIMS?

Standardization is the key concept that facilitates interoperability among organizations in incident response according to the National Incident Management System (NIMS). When organizations adopt standardized protocols, procedures, and terminology, it ensures that all entities involved in an incident response are speaking the same language and following the same guidelines. This uniformity is essential for effective coordination, as it minimizes confusion and allows for seamless collaboration across various agencies and departments during emergencies.

Standardization also encompasses the development of communication systems, roles, and responsibilities, which helps multiple organizations to work together efficiently. Whether it's sharing information, resources, or strategies, having a common framework provided by standardization is crucial for enhancing operational efficiency and effectiveness in crisis situations.
