How about, "Multiple versions do not count as multiple versions if they were done by members of the same species"? I mean, we're all human, and many of us have a tendency toward the same sort of errors (off-by-one errors, inability to find all sources potentially affected by a certain change, etc). Multiple versions can certainly help, but it doesn't help nearly as much as one would like. It sure would be nice if, given a probability P of error, N versions would make it P**N. With software, it's not that good, because my errors are not independent of your errors, because our brains think alike to some extent. By the way, the original poster should look at SPARK. - Bob
