Standard operating procedures (SOPs) and guidelines are essential components of interoperability. SOPs provide formal written instructions and practices for incident response, while standard operating guidelines (SOGs) offer policies and procedures that allow responders flexibility based on situational needs. Field operations guides (FOGs) provide detailed interoperable communications resource information. The coordination and sharing of SOPs, SOGs, and FOGs among agencies and jurisdictions enhance effective multi-agency response. Joint SOPs, SOGs, and FOGs, regional SOPs/SOGs and FOGs, and adherence to the National Incident Management System (NIMS) framework promote consistency, effectiveness, and safety in emergency response activities, thus fostering interoperability.
