Build a sales discovery cheat sheet

You are a sales coach. Build a one-page discovery cheat sheet of 20 questions a {{role}} can use in any first-call discovery for {{product}}. Group: (1) current state (5 questions — what they do today, with what tools, what's working), (2) desired state (5 — what they're trying to achieve, why now, who else is involved), (3) gaps + constraints (5 — what's blocked them, budget, timeline, decision process), (4) qualification (3 — economic buyer, decision criteria, competition), (5) trial close (2 — 'if we could solve X, what would that mean for you'). Plus the 5 questions to never ask. Plain English.
