Ans: Identify the major use cases In this step you find the boundary of the system, identify the primary actors, list the goals for those actors, identify and write the overviews for the major use cases, and review any current use cases.Expand the major use cases In this step choose one of the use cases to expand, fill in the details, write the normal flow for the events in that use case, decompose the flow into subflows if needed, list the possible alternate or exceptional flows, and describe how the actor or system should react when an alternate or exceptional flow occurs.Confirm the major use cases Review the set of use cases, and revise as needed, and then start at the top again.Create the use-case diagram Draw the system boundary, place the use cases on the diagram, place the actors on the diagram, and then draw the associations. Revise as needed. Response: See page 178
