(a) Read and understand the case study on pages 67-68 back in Chapter 2, the one entitled “Sandia Medical Devices.” ItSample Page introduces an important new Android app to be developed by Sandia Medical Devices. You will be the lead systems analyst in this effort. (b) Now that you understand the project, go on to read and understand your assignment this week (on page 92 at the end of Chapter 3), which is also entitled “Sandia Medical Devices.” (c) Please turn in this assignment by uploading a document with the results of your three tasks this week: Identify all the types of actors who will use RTGM. Using the actors whom you identified in question 1, develop a list of use cases based on the user goal technique. Draw a use case diagram for these use cases. Using the event decomposition technique for each event you identified in the description, name the event, state the type of event, and name the resulting use case. Draw a use case diagram for these use cases. It works best to use Visio to construct the two use case diagrams. Then you can copy/paste the two diagrams into the Word document where you listed the use cases for task 2 and the descriptions, event names, event types, and use case names for task 3.
