Start at the station
Auditors usually walk straight to a workstation and ask the operator to open the current instruction. Then they compare the revision on the floor with the controlled source. That is where most document-control findings start.
- Is the instruction available at the point of use — not in an office, not in a shared drive, but here?
- Does the revision on screen match the current revision in the master document list?
- Can the operator explain how they know this is the current revision?
Then show the revision trail
The next question is usually history. Who published this revision, when did it become current, what did it replace, and if there was a rollback, why did that happen?
- Publish date and author for every revision — automated timestamps are stronger than manual entries
- Superseded status clearly marked — auditors should see that old revisions are not accessible at point of use
- Rollback records if a revision was withdrawn after publish — the reason and timestamp should be visible
If you use acknowledgement, show it cleanly
If you use audit mode, show the required-reader status: acknowledged, pending, overdue, and where relevant who opened but did not yet acknowledge. If you use anonymous QR delivery, be ready to explain how latest links and revision history support your documented distribution method.
- For audit mode: per-operator acknowledgement records with timestamps and revision references
- For anonymous mode: document the QR delivery method in your QMS and show that QR links serve the current revision
- Due-date follow-up: show how overdue readers are identified and chased after the revision due date
Be ready to talk about obsolete copies
Auditors specifically check that obsolete documents are not in normal use. With paper systems, that means checking binders for outdated pages. With QR delivery, scanning the latest link should show the current revision immediately, while superseded revisions stay outside the normal live path.
- Superseded revisions are marked and not served via the primary QR link
- Paper copies: show recall procedure and evidence that outdated copies were collected
- QR delivery: demonstrate by scanning the code — the auditor sees the current revision directly
Brief the people who will be asked
Brief your team on a concrete example. The operator should be able to scan the QR, point to WI-042 Rev C on screen, and explain why they trust the latest link to open the current revision.
- Operators should be able to scan the QR and point to the revision marker without hesitation
- Supervisors should have the acknowledgement report ready and know how to pull it up on screen
- Quality manager should have the controlled document list reconciled with RevQR's document list
