Provide training records, permitted project summaries, internal role descriptions and other evidence that accurately explains the knowledge, deciding in advance with the applicant what needs special handling.
Choose records that answer the actual question
A reviewer needs enough detail to understand the process and the person's role in it, not an unexplained bulk document dump. Identify which specific examples establish the key facts, and coordinate with legal counsel before deciding what confidential detail can be shared and in what form. Training records, project evidence, and knowledgeable supervisor accounts carry more weight than calling the worker critical.
Identify the custodian and date for every technical record. For documents, use a privilege and confidentiality review to decide what can be disclosed, summarized, or protected. A concise exhibit that explains the process and the employee's role is more useful than a large technical archive with no factual bridge.
Hypothetical example: An industrial-coating firm cannot disclose a client formula; it should prepare a controlled explanation of the employee’s process knowledge rather than submit a conclusory secrecy claim.
