# Industry: shop-floor and supplier control with evidence

_Line checks with photo and time, risk-based supplier approval and closed non-conformities._

**Responde a:** paperless shop-floor quality control · industrial supplier documentation · production batch traceability · factory non-conformity management · IATF ISO audit documentation

In a factory everything is checked and almost nothing can be proven. Reports are on paper, photos are on different phones, and supplier approval lives in a spreadsheet one person maintains. It works until the first customer complaint or the first second-party audit.

**En corto**

- Line checks happen on a phone, with photo and time tied to the point.
- Suppliers are approved by criticality, not all the same.
- Non-conformities have an owner and closure evidence.
- The auditor's dossier is exported rather than compiled.

**Approving by criticality** — A supplier who can stop the line needs a different file from a consumables supplier.

## Goods-in is where the money is saved

Catching a raw material problem at goods-in costs a return; catching it on the line costs a batch; catching it at the customer costs the complaint and the reputation. A goods-in check with evidence moves the finding to where it is cheapest.

## Batch traceability

When a complaint lands, the question is always the same: which raw material went into that batch, what checks were done and who did them. If that is dated and evidenced, the answer takes hours. If it is on paper, it takes days and comes with doubts.

> [!WARNING]
> Digitising a checklist by copying all forty points from paper is the classic mistake: if it takes twenty minutes, it gets filled in from memory at the end of the shift and does not work as evidence.

## Frequently asked questions

**Does it help with an IATF or ISO audit?**

For the documentary side yes: dated evidence, supplier control and corrective action follow-up with closure.

**Can it be used on the line, with gloves and no signal?**

It runs from a phone. Without signal it is worth checking it uploaded before closing the shift.

**Can I request different documents by supplier criticality?**

Yes, one process per category. That is precisely what is recommended.

**What about haulier documentation?**

Same circuit: requested, expires, warns. It is one of the most commonly forgotten.

## Ejemplos

**A customer complains about a batch and asks for full traceability in 48 hours.**

- Filters by batch and pulls that shift's checks with their photos
- Attaches the certificates of the raw material that went in
- Adds the non-conformity raised and its action plan

→ A documented answer within the deadline, which is what stops the complaint escalating.

**A client audit asks for evidence of plant control over the last six months.**

- Checks the period's records with their dates
- Provides the log of real operations, not the procedure
- Records what was handed over

→ The control moves from assertion to evidence and the audit is prepared in an afternoon.

**A client asks for the traceability of a specific batch.**

- Checks that batch's file

→ You answer per batch rather than per catalogue.

**A supplier certificate expires with material on the floor.**

- Records expiries per supplier

→ The warning arrives before producing with it.

**The trace breaks between production and despatch.**

- Ties the batch produced to the outgoing delivery note

→ The batch is followed to the customer.

**A problem must be contained and nobody knows what shipped.**

- Checks which batches went to which customers

→ Those affected are warned rather than the whole base.

**Each shift records differently.**

- Uses the same form for everyone

→ The history is comparable.

**Plant sheets are written up at the end of the day.**

- Records at the moment

→ The data is exact rather than reconstructed.
