Scenarios test the world. Windtunnel tests you. Before a board meeting, an earnings call, a lender review, a briefing or a negotiation, you rehearse it against counterparts who hold your organization's own evidence: its scenarios and their probabilities, the signals it watches and how they moved, this morning's edition, its named competitors and risks.
One sentence in
Open Windtunnel and say what room you are walking into, in your own words: *"Board meeting Thursday — we're asking for another $4M on the permit timeline, and the chair will want to know why now."* Choose the pressure (easy, standard, challenge) and press Build the room.
Numen reads the sentence with your organization's profile and the lattice and builds the room: the kind of room, who is in it, the five to eight questions it will press on (each tied to the evidence that makes it likely), and the numbers to have in hand. Building the room costs 25 credits.
You can also start from a scenario (Rehearse the room on any scenario page) or from an item in the morning edition (Rehearse under the item). The room is then built around that subject.
The brief
The room read is yours to edit before anything runs. Trim a question or add one, mark the hard ones, sharpen what a counterpart cares about, seat a Palanor persona, drop a deck (PDF; it is read into the evidence when the run starts), and write what you intend to say. Print the brief gives you the sheet to walk in with. Keep as a brief stops here, at no further cost.
The depth
- Quick fire (about five minutes, 60 credits): the questions one at a time, answered in writing, then the debrief.
- Live run (5 to 20 minutes, 180 credits): the counterparts in the room, in text or voice. In a panel, one person speaks per turn and hands the floor to the next. The numbers rail beside the conversation shows the evidence the room is working from; on a challenge run it is hidden, because the real room has no cheat sheet.
A counterpart may only cite numbers that appear in the evidence. When you state a number that conflicts with it, they press.
The debrief
Readiness, 0 to 100, with Numen's one-line verdict: 80 and above would hold the room today; 60 to 79 would hold it with the cracks fixed; below 60, the room would have you. Then what held and what cracked, each with your exact words; a better line for each crack; and every checkable claim you made, marked matched, contradicted or unverifiable against the evidence, with a link to it.
Questions you did not answer each carry Add to Study: the question becomes the note and its evidence signals join the panel, so it stays open until you can answer it. Run it again rebuilds the room from today's evidence; scenarios and signals move, and the questions move with them. Readiness by room kind sits on the Windtunnel door, so a third board rehearsal can be compared with the first.
