Use genuine experience and relevant organizational records, with an account of the actual processes or products understood. A certificate may support a fact but is not the whole standard.
Connect experience to the task
A broad project list does not automatically demonstrate the knowledge needed for this assignment.
With the organization's own records: protocol authorship and revision history, validation and deviation reports, training materials, and a signed statement quantifying how many employees hold comparable knowledge and how long a replacement would take to train. Dated project records, escalation histories, internal design or procedure documents the person authored or maintained, training material they wrote, and manager statements pointing to specific work. Evidence should include the library itself or representative extracts, revision history, the training curriculum, records of who has completed it, and a comparison explaining what a competent planner hired in the United States would not know. Version histories showing who revised a procedure and when, training records showing who taught whom, and internal correspondence discussing a problem and its solution all place the employee inside the company's methods rather than merely near them.
