Some authorities[1] disagree, and with good reason.  Downstream
(post-release) testing and fixing is an order of magnitude more
expensive than upstream review and testing.  It is possible to get the
users involved upstream (even in the design and specification stages),
but this requires precisely the fine modularization that Keith says
may be an inferior alternative in many applications.

Steve, can we reprint your editorial (and our response) on FSB?  Or
can you put it up on the Web or something?  Or is it already
available, maybe?
