Create a Use Case Diagram and Use Case Descriptions for a fuel pump at a gas station.
First, create a list of items in the:
- System Context, and
- Irrelevant Environment.
Second, create a use case diagram based on the items identified in the System, System Context, and Irrelevant Environment. Use case descriptions should be based on the extended format specified in the slides. Remember, you must have at one use case description for each use case within the use case diagram (i.e., more than one use case description).
Third, identify at least one change that would expand the System Context (i.e., move something from Irrelevant Environment to System Context) and one change that would contract the System Context (i.e., move something from System Context to Irrelevant Environment).
Finally, illustrate or discuss how the changes to the System Context would change the Use Case diagram. You don't have to re-draw the diagram, but there should be enough information about the impact to your diagram for it to be able to re-created based on the impact.
