Big teams

[Grim Tuesday]

With my team quickly growing, we have been keeping a similar system of hierarchy/membership as when we were a small team. We require that all members have as many hours as possible to go to all competitions, etc...
We have about 55 members, and will probably grow more next year.

I was wondering how many of the "superteams" deal with stuff like member attendance, keeping the team at manageable level (cuts), gender balance, etc...

On a related subject, our early season design process is also tailored for a smaller team. How, in detail, do the superbig teams do it? Do you guys just have a small "design corps?" Or is it a full out team effort?

Thanks in advance!
