Does someone have to enter extra data for this?

Lots are captured once on the order, and status is marked on the floor anyway. What comes afterwards — label, paperwork, passport — takes that data instead of asking for it again.

How deep does the assignment go?

Down to the individual unit: pane, sash or panel. Not to the delivery and not to the order, because both are too coarse for a complaint.

What happens when something breaks in production?

The reason is recorded per component, separately for glass and film, and feeds the re-order with the supplier. The unit stays the same unit — it does not get a new record.

Do we need the digital product passport for this?

The other way round. Traceability is the precondition; the passport is one possible output of it. Capture per unit and you can issue the passport at any time; without it, no deadline will help.

How long does the data stay available?

As long as it is needed, which is considerably longer than the order. Complaints, maintenance and spare parts ask about a unit that order processing closed long ago.

Traceability in window and glass production

The short answer

Traceability means this: for every manufactured unit you can say which lots it is made of, who worked on it and when, and in what state it left the plant. Not for the delivery it came from, but for that one unit.

The difference only shows in a complaint. If the lot hangs on the delivery, "which units are affected?" is an investigation. If it hangs on the unit, it is a query.

What is captured

What hangs on a unit

Captured where the unit is made — not afterwards in the office.

Lot numbers

Film, copolymer, glass manufacture and glass lot are captured on the order and travel from there into passports, labels and papers. Captured once, used everywhere.

Status per unit

A shop-floor view for touchscreens shows where each unit stands. What is marked there is the status — there is no second list to keep up afterwards.

Photo and video evidence

Evidence hangs on the unit. How it looked when it was marked complete is therefore a file on the right record, not a memory.

Breakage reasons per component

When something breaks, the reason is recorded per component — glass and film separately. That becomes the re-order with the supplier, and over time the answer to why it keeps happening.

Who and when

Behind every mark there is a person and a timestamp. Not to police staff, but so that a question three months later still has an answer.

The case you build it for

A supplier reports a problem with a lot. The question is not whether goods are affected but which — and at which customers they now sit. Without per-unit assignment the answer is a working day and an uneasy feeling; with it, the answer is a list.

The same body of data later carries the digital product passport. That is not a second project but the same capture with a different output.
