What is the national incident management system based on?

The National Incident Management System (NIMS) is based on a comprehensive, standardized approach to incident management that integrates all levels of government, the private sector, and non-governmental organizations. It emphasizes a unified command structure, coordinated response efforts, and effective resource management to enhance the ability to prepare for, respond to, recover from, and mitigate the impacts of incidents. NIMS is designed to be flexible and adaptable, allowing it to be applied to various incidents of different sizes and complexities.
