For Algeria, fleet customer, technical team, and aftersales team should jointly approve residual-value basis instead of relying on a verbal handover. Review the project specification, trial record, and approved cost or service assumptions, then run trial operation with the first batch on real shifts, record energy use, faults, and downtime, and sign the two conclusions separately. Keep the document version, project, route, vehicle group, and acceptance stage, and the decision on residual-value basis together. The Algeria team can also use this related FAQ to align purchase and delivery records. For a first batch or high-risk item, arrange at least 2 independent checks for residual-value basis, with both records following the same project, route, vehicle group, and acceptance stage. Revise the specification or delivery phase before releasing later batches when residual-value results miss acceptance. This record covers only residual-value basis under fleet programs; other items require separate approval.
