Business Impact Assessment
Scored 1 (negligible) to 5 (severe) across the six impact categories from the Phase I BIA scope.
Delayed hazard response (signal knockdowns, debris, washouts) increases exposure.
FEMA PA claims require contemporaneous cost capture.
All-district work order stoppage; winter ops dispatch reverts to radio and paper within one shift.
Vendor operates from a single region; two brownouts in the last year during storm-surge usage.
Recovery Objectives
Proposed via BIA- Minimum availability
- 99.5%
- Service window
- 24×7 during winter ops; extended business hours otherwise
Workaround Feasibility
Paper work orders and radio dispatch feasible for ~24h; cost capture backlog grows quickly and threatens FEMA claims.
Dependencies
Systems, vendors, data feeds, infrastructure, and personnel this application depends on. Single points of failure are flagged.
| Dependency | Type | SPOF | Notes |
|---|---|---|---|
| Vendor SaaS platform (single region) | Vendor | SPOF | No cross-region DR commitment in current contract |
| SCEIS Interface Hub | System | — | Payroll and cost object sync |
| OneMap Enterprise GIS | System | — | Asset locations, route referencing |

Tier Assignment Traceability
Operational disruption score of 5 (R2): statewide maintenance dispatch halts. Safety score of 4 reinforces but does not trigger Tier 0.
