Dear Archibald,

Many thanks for a nice posting  about the pros and cons of N-version
programming.   This is for some reason an emotional issue, with protagonists
and critics arguing vehemently.
  There is no doubt that IF USED PROPERLY N-version programming has some
value.  It is less effective than some techniques, more effective than
others.  It can be accomplished  more easily than Formal Methods, but
is probably less effective.
   You pays your money and you makes your choice  :-)
Best regards,
Charles R.
P.S. I should point out to the FM protagonists, who delight in
extohling examples of how N-version programming has failed, that
is is also possible for FM projects to fail.   Examples available
on request.
  Anything can be screwed up if you try hard enough.  :-)
