Part of the Materials series on the Mobtag platform.
In short: Traceability is a chain, not a sticker. The lot in the joint must match the MTC in your hand and the book the site manager will defend when a 9001 surveillance audit asks a random why in the middle of a close-out.
When materials are moved without the doc moving with the same identity, you are not in “a bit of admin” territory—you are in a claim and rework conversation with your customer, your insurer, and your QHSE lead all at once.
| Break in the chain | How it is discovered |
|---|---|
| The wrong lot issued to a weld | NDT, not the stores desk |
| Two systems for “in stock” | A physical count, month-end |
| Cert on email, not on the batch record | A customer audit, late Friday |
Summary: Link certificates to lots, issues to work orders, and returns to what actually moved on the day—so stock movement and documentation match when the pressure is on, not the night before a visitor arrives.
