Field Workforce Route & Mileage Risk Analysis
Problem Focus: Spatial Data Ambiguity × Workforce Compliance Governance
A spatial verification model designed for field sales operations that replaces unguided manual coordinate spot-checks with candidate-location confidence scoring and a 3-tier review triage, reserving managerial context for formal decisions.
Operational Friction & The Pre-System State
Field sales representatives historically recorded daily client visits on paper sign-in sheets, providing zero spatial visibility for HR or Finance. When mobile GPS check-in was introduced, it generated large volumes of coordinate points but immediately created operational ambiguity.
- Raw coordinates frequently reflected home-adjacent check-ins and unlinked transit locations with no clear medical facility record.
- With ~15 field reps averaging 2–5 daily check-ins, manual inspection of every coordinate was labor-intensive, inconsistent, and unscalable.
- Dense healthcare clusters (multiple clinics sharing an address or plaza) made single-coordinate geometric mapping inherently ambiguous.
The Governance Dilemma & Rejected Naive Rules
The obvious technical instinct is to apply rigid geometric automation. However, automated rules create severe false certainty and damage employee relations when applied to field operations.
Why Rejected: Physical proximity alone cannot prove client meeting intent. In dense medical clusters, snapping creates arbitrary false positives.
Why Rejected: Field representatives require legitimate tactical agility (urgent prescription deliveries, traffic re-routing). Rigid geometric assumptions penalize necessary field flexibility.
System Design & Processing Pipeline
The model organizes raw daily records into structured workday event groups, compares actual claims against baseline route models, and evaluates candidate locations transparently. Crucially, raw location records may be ambiguous or represent multiple plausible locations (e.g., dense clinic buildings). The system preserves this uncertainty by calculating confidence scores rather than converting uncertain data into a false binary conclusion.
Visual Evidence & Interface Walkthrough
Selected interfaces from working prototypes, showing how the process and governance principles above translate into operational workflows.
Individual Punch Assessment & Multi-Candidate Matching
GPS coordinates are not converted directly into misconduct decisions. Distance, known-client proximity, nearby institutions, and candidate locations are assembled as evidence before ambiguous records are routed for human review.
Proves that the system utilizes multi-candidate location scoring and proximity indicators, presenting structured evidence to human managers for ambiguous punches rather than triggering automated disciplinary actions.
Weekly & Daily Risk-Based Review Queue
Instead of reviewing every attendance record, managers receive risk-prioritized review queues that concentrate attention on records requiring contextual judgment.
Demonstrates 3-tier risk prioritization (Normal vs. Priority Review) at the daily/weekly level, shielding managers from manually spot-checking coordinate streams for 15+ field sales reps.
The system strictly produces review priority signals to optimize managerial bandwidth. It never issues automated penalties or formal misconduct judgments. Any formal inquiry or compensation adjustment strictly requires a manager to review the operational context directly with the employee.
Implementation Maturity & Scope
Implemented · Data accumulating in 2026The modular data pipeline (ingest, clean, route estimate, candidate scoring, triage) is fully implemented and validated with automated test suites.
Implemented · Data accumulating in 2026
Integration of automated calendar schedule cross-referencing for high-density multi-practice buildings.
Deliberate Trade-offs
- •Accepts residual ambiguity and requires ongoing manager review effort rather than offering a deceptively simple automated verdict.
- •Prioritizes employee trust and defensibility over aggressive automated cost-cutting.
Known Operational Limitations
- •Multiple independent clinics operating at the exact same street address cannot be differentiated by GPS coordinates alone without calendar logs.
