ask for a volunteer to try to perform a task on a site belonging to one of the other attendees. These tests last less than fifteen minutes, but in that time the person whose site is being tested usually scribbles several pages of notes. And they always ask if they can have the recording of the test to show to their team back home. (One person told me that after his team saw the recording, they made one change to their site which they later calculated had resulted in $100,000 in savings.)
