It may help explain the project, but the employee’s contribution needs to be identified accurately. Team authorship does not establish that one person performed every task.
Mark the relevant work without rewriting history
Use genuine role records or explanations from people who know the assignment. Distinguish the employee’s decisions from general team output. If confidential records are involved, coordinate an appropriate way to explain the relevant facts rather than submitting unexplained or misleading excerpts.
Contemporaneous internal records: design and configuration documents, change histories, authored training material, project files, and any registered intellectual property, together with the standard relationship and payroll evidence. Attach the table of contents, the sections the employee authored with their revision history, and any passage that expressly leaves a decision to a qualified operator, together with a short statement explaining what each attachment proves.
