Who are RTGM's stakeholders? 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 medi- cal personnel the same for every patient? Can they vary over time for the same patient? What are the implications for the system's functional requirements? 5. Briefly describe some possible nonfunctional requirements for RTGM. Software Design and Development Submit your work in the Assignment 2 folder under "Dropbox" Look at the end of the Chapter Case "Sandia Medical Devices" at the end of Chapter 2 and answer all the questions (1-5). Purpose of the assignment: You should be able to analyze the case and then be able to identify stakeholders and user requirements and functional requirements.
