EOC teams vary widely. Organization of the EOC staff can vary based on:
- Jurisdictional/organizational authorities
- Staffing
- Partner and stakeholder agencies represented
- EOC facilities
- EOC communications capabilities
- Political considerations

NIMS identifies three common ways of organizing EOC Teams:
- ICS or ICS-like structure

Like ICS, EOCs utilize the NIMS management characteristic modular organization.
