Traceability as a by-product, not a project

A customer calls: a batch of parts is failing in the field. Which raw-material lot went into it? Which other deliveries used the same lot? Which machine, which shift, which parameters?

In many plants, answering takes days of searching through receiving documents, paper travellers and spreadsheets. Sometimes it cannot be answered at all.

Why reconstruction fails

Traceability reconstructed after the fact depends on everyone having written everything down, consistently, in places that can be connected. One missing link — a pallet relabelled, a lot split by hand — and the chain breaks.

Recording it as the work happens

The alternative is to make genealogy a side effect of normal work:

• receiving creates lots with their supplier data and quantities
• loading material on a machine links the lot to the active work stage
• declaring output creates the produced lot and its link to what was consumed
• moving and shipping handling units keeps their contents and history

Nobody “does traceability”. Operators do their job on screens that record what they used and what they made.

Quality on the same chain

When quality results, defects and holds attach to the same lots, containment becomes precise: hold exactly the affected lots, release the rest, and show the customer the evidence.

That is the approach in Metalya: materials, production and quality on one model, so the chain from supplier to customer is always complete.
