  1. Use the CRUD technique to add any necessary events to the event table above. See page 147 Figure 5-13 for an example. Highlight any new use cases in italics. You should be able to identify a minimum of 5 to 7 new use cases. 25 points

  1. For the “add new musician” use case, create an analysis-level SSD. You will only have two lifelines: one for the actor, another for the “system”. See figure 5-11 on page 146 for an example. Use detailed message notation as shown on page 141 figure 5-8a. Do NOT use “alternate notation” as shown in figure 5-8b. In other words, clearly show a response from the system for every message sent by the actor. 35 points
