The idea
Expertise changes which differences, dependencies and consequences appear important. The missing information may exist in the connection rather than inside either person's domain.
Worked example · illustrative
An empty table near closing time
Situation. A restaurant has a table free at 8:45 PM, so the person taking bookings offers it to a couple who call. The kitchen closes at 9 PM, and the chef is unhappy about the late booking.
The tempting conclusion. The table is free and we’re still open. Why turn people away?
What changes the view. The chef explains that some dishes take 40 minutes to prepare. From the booking desk, there’s room for two more guests. From the kitchen, there may not be time to cook what they order before closing. The question is no longer just whether a table is free, but what meal the restaurant can offer at that time.
What this supports. Talking it through could lead to an earlier last booking or a smaller menu later in the evening. The booking team could then tell guests what to expect. Seeing the table and the meal together makes it easier to find a plan that works for both the guests and the kitchen.

You do not need to replace another expert or defer to them automatically. Check your interpretation with the people involved; apparent fluency in their language is not proof that you understand their constraints.
