Show the actual calendar periods and work performed. Concurrent projects are not separate consecutive years, and a client list alone does not establish duration or relevance.
Build an evidence-backed chronology
Record start and end dates, duties and the specialty related to the agreement. Link entries to contracts, references and other reliable records. Ask authors to confirm facts they know rather than repeat a résumé total. The alternative must be assessed under the management-consultant listing; do not assume every period of business ownership or general employment counts.
Create one row for every claimed period with dates, duties, and the writer who has direct knowledge. Hypothetical example: a heritage-theatre turnaround adviser has only two venue directors able to confirm seasonal assignments. Contracts, invoices, tax records, and contemporaneous messages can settle periods a new reference cannot prove. Gather primary chronology records before asking anyone to sign a narrow factual letter. The qualification record must align with the listed-profession route actually relied on. Do not treat an optimistic business explanation, a later-created letter, or a family arrangement as proof of a missing eligibility fact.
