Expect to use the module viewtype for
On the other hand, it is difficult to use the module viewtype to make inferences about runtime behavior, because this viewtype is a partition of the functions of the software. Thus, a module view is not typically used for analysis of performance, reliability, or many other runtime qualities. For those, we typically rely on component-and-connector and allocation views.
