(a) Read and understand the case study on pages 67-68 back in Chapter 2, the one entitled "Sandia Medical Devices." It 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:

1. Identify all the types of actors who will use RTGM.

2. 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.

3. 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.

Sandia Medical Devices Medical monitoring technology has advanced sig- or low glucose are more susceptible to such expensive, nificantly in the last decade. Monitoring that once long-term complications as vision, circulatory, and required a visit to a health-care facility can now be kidn performed by devices located in a patient's home, or Sandia Medical Devices (SMD), an Albuquerque carried or worn at all times. Examples include me manufacturer of portable and wearable medical moni sures of glucose level (blood sugar), pulse, blood pres toring devices, has developed a glucose monitor em sure, and electrocardiogram (EKG). Measurements bedded in a wristband. The device is powered by body can be transmitted via telephone, Internet connection, heat and senses glucose levels from minute quantities and wireless data transmission standards, such as of perspiration. SMD is developing the Real-Time Glu Bluetooth.

The system's vision statement reads as patient of problems and can automatically transmit follows: data and alerts to a central monitoring application (see Figure 2-17) dney problems RTGM will enable patients and their health-care providers to continuously monitor glucose levels, Health-care providers and patients incur sig nificant costs when glucose levels are not maintained within acceptable tolerances. Short-term episodes of very high or very low glucose often result in expensive visits to urgent care clinics or hospitals. In addition, patients with frequent but less severe episodes of high immediately identify short- and long-term medi- cal dangers, and rapidly respond to those dangers in medically appropriate ways SMD will develop the initial prototype software for smartphones with Bluetooth capability running
