The first two types of research produce methods of development or of analysis that the authors investigated in
one setting, but that can presumably be applied in other settings. The third type of research deals explicitly with
some particular system, practice, design or other instance of a system or method; these may range from narratives
about industrial practice to analytic comparisons of alternative designs. For this type of research the instance
itself should have some broad appeal—an evaluation of Java is more likely to be accepted than a simple evaluation
of the toy language you developed last summer. Generalizations or characterizations explicitly rise above
the examples presented in the paper. Finally, papers thatdeal with an issue in a completely new way are sometimes
treated differently from papers that improve on prior art, so "feasibility" is a separate category
