ICS Feature: Modular Organization
The ICS organizational structure:
  • Develops in a top-down, modular fashion that is based on the size and complexity of the incident.
  • Is determined based on the incident objectives and resource requirements. Only those functions or positions necessary for a particular incident are filled.
  • Expands and contracts in a flexible manner. When needed, separate functional elements may be established.
  • Requires that each element have a person in charge.
