• Use Case purpose

  Loosely quoting from the above reference: once you have a problem statement describing a problem that you need to solve, the next step is to look at the problem itself...from the perspective of dynamic behavior. The dynamic definition of the problem focuses, not on what has to be done, but on how you do it. That is, you look at the things the users have to do to solve the problem. The main tool you use to structure your thinking on that dynamic behavior, to discover/understand what the dynamic behavior is, you do a use-case analysis."
