The idea was the same every time. The room was not. The board wanted the number, the engineers wanted the mechanism, the customer wanted what changes for them on Monday. So we wrote it four times, and the fourth one was always the worst.
Not because the fourth room mattered least, but because by then we were copy-editing instead of thinking, and the four copies had already started to disagree with each other about things we thought we had settled.
Deck Factory is the fix we wanted: say the thing once, properly, then let the tool recalibrate it per audience. It is the same idea in every room, told in the language of that room, and there is exactly one place to correct it.
