Great post! This looks like a very useful tool. Do you find that you (as designer) fill it out and then talk about it with other people, or do you bring it out during conversation and fill it out as you talk with other members of your team? Have other people adopted it or just the designers? Also, what do you do with them after the conversation? Do they end up someplace people see/refer to them afterwards, or is the value converted to code quickly?
