Check supplier evidence for identity, scope, period and relevance, then record gaps, review decisions and follow-up without losing the original source.

## Start with the claim, then inspect the document

A file being present is not the same as a claim being supported. First identify the answer or requirement being reviewed. Then check whether the evidence actually addresses it for the entity, site, activity and period in scope.

Use this checklist as a review aid alongside your own assessment criteria. It does not establish document authenticity, legal compliance, independent assurance or a sustainability rating.

## Eight checks before you record a decision

- [ ] Identity: does the named entity match the supplier response, or is the relationship between entities explained?
- [ ] Scope: does the record cover the relevant facility, activity, product or process?
- [ ] Period: is the issue date, validity period or reporting period appropriate for the question?
- [ ] Completeness: are the relevant pages, annexes and qualifications available and readable?
- [ ] Source: who issued or created the record, and can the claimed source be checked where necessary?
- [ ] Relevance: which exact passage or value supports the answer being reviewed?
- [ ] Consistency: do names, dates, units and scope agree with the other records in this assessment?
- [ ] Traceability: can another reviewer find the original record, the reviewed version and your reason for the decision?

## Separate extraction, checks and judgement

Text extraction helps a reviewer find names, dates and values. A rule can flag a mismatch or a missing value. Neither step, on its own, proves that a supplier statement is true or that a document is genuine.

Record what the check established and what it did not. When a scan is unreadable or a value cannot be located confidently, request a clearer record or send it for review. Do not turn an extraction failure into a confirmed supplier failure.

## Read a certificate within its stated scope

Inspect the entity, covered sites, stated activity, issuer and dates. A certificate for one activity or facility should not be treated as evidence for unrelated operations.

Where certification status needs independent confirmation, use the issuer or the relevant verification route and retain the result of that check. ISO explains that external certification bodies issue certificates; ISO itself does not certify organisations.

## Keep the outcome more useful than a tick box

Use your team’s defined decision states. A practical review record distinguishes evidence accepted for the stated criterion, clarification requested, not applicable with a reason, and not yet reviewed. These are example states, not a claim about labels in Ardera.

Link the outcome to the source and write a reason. If a gap remains, record who will follow it up, what is needed and when it should be revisited. An unanswered request is still an open item.

### Illustrative review note

Clarification requested: the response covers April to June, while the attached operating record covers January to March. Ask for the period in scope. Keep the original attachment and this note in the assessment history.

## Close the finding with evidence

When a revised document or answer arrives, review it against the original request. Record the new source version and the reason for closing or keeping the finding open. Retain the earlier decision so the history can be understood later.

Before exporting the assessment, check that unresolved findings remain visible and that the report makes its scope and review date clear.

## Final review

- [ ] Scope and review period are explicit.
- [ ] Conclusions link to the reviewed evidence.
- [ ] Open findings have an owner and next step.
- [ ] The assessment decision and its reason are recorded.
