ISO are not regulations they are standard of operating at, they can define how anyway they wish. It began with a standard at 9000 and since has progressed to standards that are much higher. Without data and without any use of coding they will never move up in standards.
It is multifaceted and in that it addresses functions every manufacturing entity have differentiated functions that are all relational, in that they affect each other.
Not documenting parts as sets and associating them with a tracking method is avoidance of what is rudimentary. That’s what is referred to as root cause analysis If a set of characters are associated with a specific, as in consistent, set of parts then finding parts becomes much simpler.
Each time a production run takes place then all of those units would share a set of parts and that would be reflected in a set of characters within a unit vehicles identification number. That one set of characters with the VIN would point to a specific and consistent list of part numbers. If the parts change at all in subsequent production runs, even if only one part, then the new set of characters with the VIN points to a new subsequent parts lists. That is nothing more then pulling up the initial parts list making a change to it then saving it with a new name. The first production run still references the first part list, then the subsequent run associates with the subsequent new list.
Then entering a VIN would point to a accurate list of parts consistently.
Each part should have a data sheets, who made it and also stocking location codes and also feed back metrics as for quality control. That alimenting of the data could take time, but setting up a rudimentary system takes months not decades.
