How should the interview be produced?

Send the scope and questions in advance only after an invitation is authorized. At the interview, distinguish the expert's view, independently supported facts and examples that require anonymity. Ask permission before recording or publishing quotes, and confirm names, roles and any conflicts at publication.

Use a working record with question, answer, evidence URL, qualification, quote permission and follow-up. Do not turn a paraphrase into quotation marks or imply that the expert endorses the buyer's chosen supplier. The final publication should retain material qualifications rather than extracting an absolute claim from a conditional answer.
