We have masters for bulk items such as flour silos, divider oils etc which are tied into the goods-in procedure. Bakers start their shift 5 minutes early and record traceability of all raw ingredients on a seperate sheet. All they then have to record for every mix is mix number, temperature of dough, flour silo number, sieve integrity etc. If they change batches during a shift (we try to minimise this as much as possible by buying raw materials in bulk so changes are rare - perhaps weekly) they must record the time of changeover (for product recall purposes) and new traceability codes. Works on our scale, but I accept it may have its limitations when scaled up to larger facilities.
They still moan constantly about the amount of paperwork they have to do though. I might send them over to you for a week, Bill!
