Vehicle as a Tester (VaaT)
General Motors · 2023 – 2025
Turning the assembly line into a continuous validation platform.
Problem
GM manufacturing lines were shipping vehicles with electrical defects that escaped traditional EoL testing, dragging plant build performance to 23%.
Approach
Architected an SDV 2.0 toolchain that lets each vehicle on the line act as its own tester. Built APIs bridging vehicle controllers with plant IT, designed a Power BI decision matrix for team leads, and led off-line diagnostic triage workflows.
Impact
- ▸Plant build performance: 23% → 82% in weeks
- ▸89% of held volume recovered for shipment
- ▸50% reduction in test cycle time
- ▸80% improvement in product quality ratings
