Breadth of experience to cover all issues and eventualities. No matter what question comes up, somebody on your team ought to be an answer ... or, at the very least, know enough to find and evaluate someone else's answer.

Aligned interests and motivations are key for this to be successful. First and foremost, who and how will this be funded?
