In order to thoroughly attend to every pertinent aspect of the spec, fantasai asked us each to read one sentence aloud to the group. At which point we were all asked whether we thought the sentence made sense, and to speak up if we didn’t understand any of it or if it wasn’t clear.
Rich documents the excellent and fascinating process used in a recent W3C workshop (though what he describes is the very opposite of groupthink, so don’t let the title mislead you):
I’d never come across the person-by-person, sentence-by-sentence approach before. I found it particularly effective as a way of engaging a group of people, ensuring collective understanding, and gathering structured feedback on a shared document.
