Business Impact Assessment

Scored 1 (negligible) to 5 (severe) across the six impact categories from the Phase I BIA scope.

Public Safety5/5

Loss of the common operating picture during an evacuation directly degrades life-safety coordination.

Financial / Revenue2/5
Federal Funding & Compliance3/5

FEMA PA reimbursement documentation depends on event data capture.

Operational Disruption5/5

Emergency coordination reverts to phone/spreadsheet; statewide impact during activations.

Legal / Contractual2/5

Modern IaC deployment, but single-region; no cross-region failover tested.

Workaround Feasibility

Partial (manual)

WebEOC and conference bridge sustain coordination at reduced fidelity; asset status goes stale within hours.

Dependencies

Systems, vendors, data feeds, infrastructure, and personnel this application depends on. Single points of failure are flagged.
