The whole process is manually operated, and various risks of manual misoperation exist;
2. the information is allocated to the professional paper surface transmission, different departments participate in the layer-by-layer transmission, the process is complicated,
3. the software configuration coding data and the document are manually managed, effective system management is lacked, and after-sale replacement and related departments are difficult to inquire and are difficult to trace.
