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.
