The Oman team can place fleet customer, technical team, and aftersales team in charge of driver-to-vehicle assignment. Each approval of driver-to-vehicle assignment should cite the same project, route, vehicle group, and acceptance stage for traceability. Review the project specification, trial record, and approved cost or service assumptions, then have each driver complete one round of trial operation on real shifts under the assignment plan, record energy use, faults, and downtime, and sign the two conclusions separately. Revise the specification or delivery phase before releasing later batches when the assignment trial misses acceptance. For a practical way to organize order evidence, see this vehicle-import FAQ. When driver-to-vehicle assignment is handed over in Oman, retain the prior decision and the reason for the revision.
