Homework Assignment 5
Due October 8, 2009

Reading assignment: SysML Guide Section 7.11, Chapter 12

Homework must be neat and readable.  At the top of every page you must include your name, the assignment number, and the due date.  Clearly indicate the question you are answering. You do not need to copy the entire question, but you must mark the question number and a brief description at the beginning of your answer for each question.

This assugnment concerns the SNUPOS case study we discussed in class on October 1.  Time will be provided during class on October 6 to work on this assignment.  Please come to class on October 6 prepared to work on this assignment.  Read the questions, think about how to answer them, and be prepared to discuss them with your team members.  

Your team may choose to submit a single response with everyone's name on it, or you may each hand in individual documents.  If you hand in individual documents, there is no penalty for similarity to other members of your group. If there was a group member who does not make class on October 6, you may include this person in a group submission but only if this group member contributes actively to finishing the assignment.  Otherwise, please ask the person to submit an individual assignment.

  1. Make a use case diagram that covers all the operational scenarios in the SNUPOS case study.
  2. Use a SysML internal block diagram to represent the interaction of SNUPOS and its external systems.  
  3. Develop an objectives hierarchy for SNUPOS.  Do not include weights.  We will discuss weights in more detail later in the semester.  Focus on capturing the major objectives of stakeholders. 
  4. Use a SysML block definition diagram to represent your objectives hierarchy in SysML.
  5. Write input, output, functional and external interface requirements for the first SNUPOS operational scenario, Creating a Study Plan.  (See pages 25-27 of the Unit 5 notes.) Write at least one of each category of requirement.
  6. Write system-wide reliability, availability and maintainability requirements for SNUPOS. (See page 28 of the Unit 5 notes.)
  7. Make a report that includes all the information given in the case study, your use case diagram, your objectives hierarchy, a verbal description of your objectives hierarchy, and the requirements you wrote. Make this into a professional looking report -- with a cover page, a table of contents, and sections for each of the elements of your partial design definition.
  8. Upload your resume to Blackboard under Assignment 5A.  Also provide proof of INCOSE or SES membership.
