^Sure. It's just that I've seen fan film groups disintegrate over accusations of one another "making amateurish mistakes" that aren't remotely amateurish at all. Planing is hugely important, but it will never eliminate all error... not even all the foreseeable ones. Rest assured, no matter how meticulously thought out in advance your plans are, problems will still occur, and most will be stupid little things that should have been obvious to, well, someone. And in every case, those involved are best served by seeking solutions, rather than someone to blame. Every set should have that sentiment on a sign someplace... "Seek Solutions not Scapegoats".
