Assignment 6

For 2/1:

Read Chapters 6 and 7.
Rewrite your use cases, taking the following issues into account:
- Incorporate feedback from class.
- Add preconditions to every use case that requires one.
- Add a minimal guarantee, a success guarantee, and a trigger to each use case.
- Do not worry about exceptional conditions. Focus solely on the main success scenario for each use case.
- Follow the action step guidelines given in Chapter 7:
  1. Use complete sentences with simple grammar.
  2. Show clearly the controller of action.
  3. Write from a third person point of view.
  4. Show the process moving forward.
    - Amount of progress is proportionate to the scope.
    - More than nine steps is a symptom of insufficient progress.
  5. Show intent, not movements
    - Avoid excessive low-level user interface details.
  6. Actions should be "reasonable"
  7. Validate, don't "check whether"
  8. Add timing details, but only if needed
  9. "User has system A kick system B."
  10. "Repeat Steps x-y until Condition."
