Should NMHS's patients be included in defining the system requirements? Why or why not? Should RTGM interact with medical professionals other than physicians? Why or why not? 2. If you were the lead analyst for RTGM, how would you determine the requirements? Be specific in your answer. List several questions you need answered. 3. What are the primary functional requirements for the system as described so far in the case? 4. Are the parameters for alerting patients and medical personnel the same for every patient? Can they vary over time for the same patient? What are the implications for the system's func- tional requirements? 5. Briefly describe some possible nonfunctional re- quirements for RTGM. Running Case Study - Sandia Medical Devices 1. Create a System Vision Document using the outline in Figure 1-8 in chapter 1. Include sections for the Problem Description, System Capabilities, and Business Benefits. You should include at least one paragraph for the problem description, five capabilities and five business benefits for the sections respectively. 2. Using the case study description in chapter 2, describe the following aspects for this project: a. List at least three stakeholders b. List at least ten functional requirements, as well as at least three usability, reliability, security, and performance requirements each for the system c. List at least five sample questions you would ask of the stakeholders in the system when gathering requirements for the system 3. Using the textbook material from chapters 3-5, list the following aspects for your use case analysis: a. Define at least three actors for your use cases b. Define at least five use cases for the system. These should be in a simple actor->verb form (e.g., actor 1 does the following in the system) at a granular level. c. Include a use case diagram for your actors and use cases. c. Write a fully developed use case of what you consider to be the most important use case using the model template in Figure 5-2. 4. List at leave five high-level security controls for your subsystems in the project using the broad categories in chapter six of the textbook. Also, list specifically what data you would encrypt and what would be the risks and potential consequences if the data were exposed to hackers.
