Consider a company who has so far used Java as implementation
language with a version of the Rational Unified Process (RUP) where
you start with use cases, implement them and use them for testing.

Suppose you are a consultant to the company and they ask you how
to move to AspectJ and how to adapt their process. How do you respond?
Some questions you should answer:

How can they use AspectJ for Java software development 
  to become familiar with AspectJ? How? Give an example.
How can they implement use cases with AspectJ? 
What is the difference to implementing them in Java?
