 - Revealing classes that need to be
   rigorously tested to make sure an error does not impact
   the other parts of the program.
-
 - Finding classes that are not well related
   to each other--in function or dependency, meaning it may be
   better to reorganize them in separate packages.
-
 - Using the polar layout to identify major dependency
   links between classes, to find groups of classes that could be
   separated into modules of their own.
