A batch record is the product. Quantities, temperatures, times and who signed it off is what allows October to match March, and it is also the first thing an auditor asks to see.
Traceability runs in both directions. A problem with a delivery of chillies means knowing which batches used it and which customers received them, and that has to be answerable in hours rather than days.
Formulas belong to the client. A recipe developed for one brand cannot appear in a product made for another, and that separation has to be built into how the information is stored rather than trusted to discretion.
Allergens dictate the schedule. Producing something containing nuts before something that must be free of them means a full changeover, so the running order is a food safety decision rather than a convenience.
