Business Impact Assessment
Scored 1 (negligible) to 5 (severe) across the six impact categories from the Phase I BIA scope.
Inspection scheduling and posting decisions are safety-relevant but operate on multi-week cycles.
NBI submission and inspection-frequency compliance (23 CFR 650) are audited; sustained outage risks metropolitan planning funds.
Stable; tablet sync outages are the common failure, tolerable for days.
Recovery Objectives
Proposed via BIA- Minimum availability
- 99%
- Service window
- Business hours
Workaround Feasibility
Paper inspection forms with deferred entry are an accepted FHWA practice for short outages.
Dependencies
Systems, vendors, data feeds, infrastructure, and personnel this application depends on. Single points of failure are flagged.

Tier Assignment Traceability
Federal compliance score of 5 but with periodic (annual/24-month cycle) deadlines and a feasible manual workaround (R3): Tier 2, not Tier 1.
