Design Checklist?

[Durgecaller]

I was assigned with the task of drawing up a robot design checklist for my team's brainstorming period. The basic function of this list is to not only encourage basic design ideas, but it will also function in winnowing out the designs that will be brought forward within the first few days following Kick-off. I was wondering if there were any suggestions that the really experienced Vets had for a second year team on such a process. I have all of the basics: Drives, Payload Handler, Basic cost, overall functions... but they just don't seem like enough. The plan is that the team will split into evenly numbered sub-teams after the kick-off and begin to brainstorm ideas of designs for this build season's robot. I know that it is possible to create a list without knowing what the objective is for the 2010 build season, but I have hit a mental block and am looking for any suggestions.
