Provide relevant duties, learning history and actual examples showing the applicant’s use of the employer’s process. Explain the limits of authority clearly.
Distinguish advising from deciding
Identify whether the applicant prepares analysis, applies a method or makes an authorized decision. Do not claim the manager’s decisions as the specialist’s own work merely because the specialist helped prepare the material. Build the record around examples rather than adjectives.
Three or four dated instances in which the applicant applied the employer's method to a real problem, showing what the problem was, what the applicant did and what followed, carry more weight than a paragraph of characterization. Hypothetical example: a native-seed production business asks an employee to document her part in its provenance-tracking method. The useful file shows the harvest and germination records she designed, the two revisions she made after field results contradicted the original assumptions, and the internal note attributing the method to her.
The unhelpful file is a letter calling her indispensable. Where a document was produced by a team, state the applicant's part and leave the rest attributed correctly, since an overstated claim discovered on one document raises a question about the whole file. Where confidentiality restricts what may be produced, redact rather than paraphrase, and record who authorized the redaction.
Where a document is dated after the events it describes, say when it was written and by whom, so a reader can weigh a contemporaneous record differently from a later reconstruction.
