Ben,

I read your book a while back (kudos BTW!) and I'm dealing with a particular
client who doesn't understand the difference between a software requirement
and a business rule. My take is that a set of rules (meaning 1 or more) make
up a requirement. Does your book describe how to drive out rules from
requirements (I can't remember)? With the emergence of business rule engines,
you could actually invalidate requirements by changing business rules. Do you
know of any organization that is researching how this can be managed?

Thanks,

Matt

there are no business rules
there are guidelines
if they can't be ignored
then the special cases will kill you
exceptions need to be made
errors need to be fixed

real requirements are fixed
derived requirements need flexibility
in case or error or omission
and unanticipated usage
