Start with the decision you need to make
A supplier assessment should help someone make a specific decision: whether to begin a relationship, accept a change, renew an approval or resolve an open concern. Write that decision down before building the questionnaire.
Name the supplier entity, site or activity being assessed, the period covered and the person accountable for the decision. A response about one site should not quietly become approval for every site in a group.
This workflow is a practical starting point for assessment teams. Select criteria with the people responsible for your procurement, quality, risk or compliance requirements; it is not a universal certification method.
1. Configure a proportionate questionnaire
Ask questions that can change the decision. For each question, record why it matters, which suppliers it applies to and what supporting evidence would be useful. Let suppliers explain why a question does not apply instead of forcing an inaccurate yes or no.
- Define the requirement before choosing a score or status.
- Separate a supplier statement from evidence supporting that statement.
- Ask for the relevant site and reporting period, not just a company-wide policy.
- Assign a review owner and an intended response date.
2. Give suppliers a clear request
Tell the supplier what is being assessed, who should respond, which records to prepare and how to ask questions. Confirm the intended recipient before sharing an invitation or an existing assessment record.
A useful invitation explains the scope and deadline in ordinary language. It should also say what happens after submission: a review, possible follow-up questions and a recorded decision.
3. Collect answers with their evidence
Keep each answer beside its supporting document or reference. Record who submitted the response and when. Ask the respondent to review the submission and confirm that they are authorised to provide it.
Treat missing, not applicable and not yet reviewed as different states. An empty field should not become a positive answer when a report is assembled.
4. Check the document before accepting the claim
Check that the document concerns the right entity, location, activity and period. Inspect the relevant passage, not only the filename. Text extraction can help locate information, but extracted text does not by itself establish authenticity or satisfy an assessment requirement.
Keep the original record and note which version was reviewed. When the evidence is unclear, record the gap and the next question rather than silently filling it in.
5. Make and record the review decision
Review the answer against the defined criterion and its supporting evidence. Record what was accepted, what remains unresolved and why. A reason should explain the judgement, not just repeat the selected status.
If a correction is needed, give it an owner, a clear requested outcome and a date for follow-up. Keep earlier submissions and decisions available when new evidence arrives.
6. Report the outcome and keep follow-up visible
A useful assessment report connects the conclusion to the reviewed evidence. Include scope, response and review dates, outstanding findings, decision owners and the conditions attached to any approval.
Agree which changes should trigger a new review, such as a different facility, an expired document or a material change in the supplied activity. Set the review schedule to the actual relationship; there is no single interval suitable for every supplier.
- Can another reviewer find the evidence behind the conclusion?
- Are unresolved items visible in the report?
- Does each follow-up have an owner and a next step?
- Is it clear which entity, site and period the decision covers?
