Updated 3 August 2026 · 7 minute read
Documents record the formal side of a matter but do not explain how a market actually works or why deals are structured the way they are. Expert interviews with industry participants close this gap - provided they are conducted openly and do not touch on trade secrets
This material describes corporate practice in working with human sources: how questions are formulated, why one party's testimony always requires confirmation, how the origin of information is recorded, and which methods are impermissible - from misleading a source to inducing disclosure of protected information
Who this material is for
