Get on a plane. Embed someone for a month. Build the relationship in person. It works every time, and it almost never happens, because the cost and the friction make it easy to skip.
So the gap stays open. A design review ends with "yes, understood" and three days later it turns out nothing was understood at all. Markups land at 11 PM local time marked urgent with no reason attached. Six weeks of good work gets built on an assumption nobody thought to check. None of it shows up in a schedule until it's already expensive.
Shared Intelligence is the convenience version of getting on a plane — a way to start building the trust before anyone boards one.
