Trying to “simplify” the simulator, for computational reasons, is crippling when it
results in omitting key features of the target domain.
In the approach of the other team, M, computational considerations do not seem to shape

the structure of the target domain. Rather, they concentrate on developing a user view of the
application. While they do note that more understanding of the domain would be useful, as
mentioned earlier, they focus on what users will do and see. Li ...
