Tracing forwards and backwards
Traceability means answering two questions quickly. Backwards: a customer reports a problem, so what went into their batch and where did it come from? Forwards: a supplier tells you a batch was faulty, so which of your jobs used it and which customers have them?
This log answers both from the Trace tab. Everything hangs on lot numbers: one for every delivery you receive, and one for every batch you make.
Tips for traceability that holds up
- Number every delivery as it arrives, and write the number on the material itself.
- Keep the supplier’s batch or heat number and cert reference alongside your own lot number; auditors will ask for them.
- Record material by lot at the point of use, not at the end of the week from memory.
- Test it: pick a finished batch at random and time how long it takes to trace. That’s your mock recall.
When the spreadsheet stops being enough
Mannin Systems does all of this as part of the day’s work: booked at the station as it happens, checked automatically, and linked to the jobs, stock and people involved. No retyping, and no Friday afternoon catching up.
