Our CAD team has about 5 people at a time, and I wouldn't suggest going much bigger than that size. Beyond that point, productivity really decreases, especially with relatively untrained members. We have one leader who leads camps and teaches CAD in the offseason. That way, the other members can do most of the actual work during the season, and the CAD leader can spearhead the overall design while delegating tasks.

In terms of keeping everything organized, we used GrabCAD, which I've seen other people on this thread mention. It's a great way to keep files organized and on record from season to season, while also being able to view and recover file editing history (in case of mistakes).

One suggestion I'd make for training CAD students is to make sure everyone understands machining capabilities before actually working on CAD design. In other words, get everyone trained on all the machines you have access to, so that you don't design beyond your resources.
