Training records, permitted project descriptions, internal qualification records, and other evidence that accurately explains the knowledge involved. Ask the company to identify what can be shared openly and what needs careful handling.
Choose evidence that answers the actual question at hand
A reviewer needs to understand the process itself and this person's experience with it, not receive an unexplained pile of sensitive files. Ask which examples establish the material facts, and how confidential details should be handled appropriately. Do not remove so much context that the remaining evidence no longer supports the claim, and coordinate the employer and legal reviewer before anything is submitted.
Begin with an index stating the fact each item proves and who may authenticate it. Useful selections include restricted training logs, redacted process maps, project assignments, internal certifications, release records, and declarations explaining the employee's contribution. The standard may be met by special organizational knowledge involving products, research, equipment, services, techniques, management, or other interests and their international-market use; advanced organizational process-and-procedure knowledge is the alternative. A common mistake is either submitting secrets without explanation or redacting away the comparison that matters. Agree on access and secure review before filing.
Hypothetical example: a Windsor robotics integrator wants to transfer a technician who mastered its unusual sensor-calibration protocol. The firm prepares a sanitized workflow, training chronology, version history, and manager statement showing how he diagnosed failures on successive installations. Source code and customer names remain restricted, but counsel can see the protocol's company context and his advanced command. The employer documents affiliate relationship and qualifying foreign employment separately rather than expecting technical exhibits to prove every element.
