Assess new features, feature changes, and defects against requirements and architecture, including impacts to safety, interfaces, allocations, verification cases, validation scenarios, and traceability; distinguish implementation defects from requirements defects, architecture gaps, interface issues, and legitimate feature changes. Develop and maintain the Yard Truck SoS functional architecture and use it to derive, organize, map, and allocate requirements across autonomy, the Drive-by-Wire Kit, vehicle systems, operator interfaces, remote operations, and supporting systems.
