Not by itself. Explain the knowledge used and its relationship to the applicable special or advanced knowledge standard.
Identify what the example establishes
Distinguish general troubleshooting skill from knowledge of the organization’s product or processes. Include the actual U.S. duties and the other L requirements.
Do not claim that a successful outcome alone establishes the classification. Separate three things a troubleshooting account tends to blur together: the difficulty of the problem, the skill of the person, and the specificity of the knowledge. Only the third is being tested.
Hypothetical example: two technicians at a lens manufacturer both diagnose a coating defect, but one relies on a general understanding of vacuum deposition while the other relies on the company’s own compensation table for a modified chamber; the second account addresses the standard and the first does not. Keep the surrounding conditions in view: a qualifying relationship between the entities, one continuous year of qualifying employment abroad within the preceding three years, and a proposed United States role that actually uses the knowledge described. Note also that the knowledge need not be secret or held by only one person, and asserting that it is will not rescue an account that fails to connect it to the organisation.
