In a bigger studio, I'd worry more about development hell, but I think Siebert's whole plan here is lean, mean and creator-controlled with as few notes and accountants as possible. I mean, when your budget is a 10th the size, there aren't enough people in the process and there isn't enough money riding on it for anything to get bogged down in notes and revisions - who ever is directing will probably only have to report to Fred, and beyond making sure people hold to a given rating (something most of the staff already has plenty of experience with by this point,) he's probably going to let them do as they please.
I mean, this isn't like writing Shrek where you're going to have a table full of expensive writers who do countless revisions, then have stand up comics do punch-up, then finally get to maybe some storyboarding, then animation, then even more punch up and so on. This is probably going to be treated exactly like 90's TV animation, which means something of an outline gets done, then storyboarding is where most of the scripting will happen, it might get a punch-up done internally by having some of the other animation folks in the studio throw some ideas out and point out missed opportunities, then that's that - you record vocals and do your animation and clean up. It's going to be a much tighter process than I think a lot of people realize. It might not have the polish of a Ghibli film or Pixar film, but it'll also be way less expensive, and it may have a certain rawness or creative stamp that's much distinct as well.
