I would typically create a Get method on the aBizobj that other
objects could query when needed; this method would get its return value
from the DataMgr object. Depending on the likelihood of the work area
changing in the life of the object, the other classes could store that
value locally to avoid continuous calls to the bizobj.

Sure - that's done all the time. Just have a Rules Factory class that
accepts the customer classification, and returns the appropriate object
to handle it.
