Business Impact Assessment
Scored 1 (negligible) to 5 (severe) across the six impact categories from the Phase I BIA scope.
All AP/payroll cost flows stop; vendor payments and payroll cost distribution fail statewide.
Federal-aid cost coding breaks, contaminating FHWA billing downstream.
Single MQ broker with no standby; adapter code has one remaining SME.
Recovery Objectives
Documented pre-BIA- Minimum availability
- 99.5%
- Service window
- Batch window 20:00–04:00 + business hours real-time
Workaround Feasibility
No manual alternative: SCEIS will not accept manual bulk postings at SCDOT volume; transactions queue until restored.
