An electronic standard operating procedure (ESOP) is useful only when the instruction matches the job being performed. A clear selection process helps operators distinguish the current approved document from an instruction for a different product, operation or revision.
What should identify the instruction? Start with the product or product family, operation, workstation and document revision. Use the same identifiers as the approved production documents. A short display title should not replace a unique document identifier when similar products have different methods.
What should happen during a product changeover? Follow the site's approved changeover procedure and confirm the new job before work starts. Check that the displayed instruction applies to that job. If document selection is connected to an order or product code, include that mapping in the acceptance checks rather than assuming it is correct.
How should revised instructions be handled? Keep the revision and approval status visible. Define when the new revision takes effect and how superseded copies are removed from normal use. An operator should have a clear contact when the screen and the production paperwork disagree.
What if the required instruction cannot be found? Use the site's escalation process. Record the job identifier, workstation, document sought and message shown on the screen. Avoid substituting a similar instruction without authorization from the responsible process owner.
Before release, check representative product variants and changeover cases on the actual workstation. Verify readable text, correct images and the ability to distinguish approved and obsolete revisions. Keep the result with the document-control records so that later changes can be checked against the same selection rules.
