Create the record from what already exists: calibration logs, revision histories, customer specifications, audit reports and training she delivered. A signed technical statement from a senior officer explaining the process and her role in it is acceptable when supported by those documents.
Turn shop-floor practice into dated evidence
Many food processors never wrote their procedures as a manual, and a petition built on assertions alone tends to draw a request for evidence. Start with the sorting-line calibration logs, which show dates, settings and who signed them. Add the customer specifications that drove the grading thresholds and any correspondence in which the quality-control lead proposed or changed a threshold. Collect internal training material she authored, audit reports listing her as the responsible person, and non-conformance reports she closed. From those, a senior officer can write a technical statement explaining the company's process, why it differs from ordinary industry practice, and how she acquired her role in it, citing the exhibits rather than asserting them. Include the U.S. plant's production plan showing the same routine will be used. Foreign-language documents need certified English translations; photographs of equipment are useful only with captions that connect them to the procedure.
Hypothetical example: a precision-ceramics producer relies on tacit knowledge passed through supervised production runs rather than a single manual. The first review creates a chronology of the employee's training, mentors, projects and access to controlled process data. Signed training records, version histories and examples of troubleshooting decisions provide a verifiable account. A declaration should explain the significance of each exhibit instead of merely attaching confidential material with no context.
