Experience says that one should not assume that there is a one to one
relationship, ("the" solution).  Some event can trigger more than one
combination of the 6 binary input variables.  And experience says that
the business users are not aware of all of the possible outcomes or
that there may be some one-to-many relationships, which may be why
they want the computer to do it.  This is a problem that occurs
everywhere.  There are various decision table techniques, but good
algorithms seem to be in short supply.
