Dividing OTA responsibility for exported cars suits an item-by-item sign-off approach: purchasing confirms the account, servers and region restrictions, technical staff confirm update release and compatibility verification, and the delivery side confirms failure rollback and customer notification. OTA requires confirming the server region, account permissions, the release party and the failure rollback plan; any feature that can't be updated overseas should be disclosed before the sale. The person in charge logs the account, servers and region restrictions first, then verifies the update release and compatibility verification. If the failure rollback or customer notification changes, the earlier conclusion no longer stands.
