You are facilitating a design review. The proposal on the table clearly touches the security area, and the security engineer in the room has not spoken. You are about to move to a decision. What is the best facilitation move?
Explication
A general invitation (option 2) is addressed to no one and is routinely answered by silence, so it does not surface the input you specifically need. Waiting (option 3) makes the decision depend on whether someone volunteers, and the meeting cannot conclude safely without their area being covered. Asking afterwards (option 4) removes the answer from the group that has to react to it, so if there is a problem the discussion has to be reconvened anyway. A specific question directed to the person with the relevant knowledge is the only option that gets the information into the room before the decision.
