If I remember correctly, you should expect to see something soon from the Virginia/DC Head Judges discussing a Core Values poster as a helpful, optional aid to teams.
In past years, I have seen discussion on this list about what types of information are helpful to have to discuss with the Robot Design judges, but I don't recall any particular mention of using the robot Executive Summary.
If you'd like a peek at how these have been described in other regions, check out
