Memorandum 1 Due Thursday by 11:59pm Points 50 Instructions: Utilize the provided template for formatting your memo; do not change any of the margins, line spacing, or fonts. There is

no overall page limit: The FMEA table may extend as long as necessary, but the text portion of your memo should not exceed 2 pages in total. Your figures for the risk matrix and reliability block diagram, must be placed within the text portion. If you use graphs or tables in your answers, they must be appropriately captioned and clear enough that I can understand them (this means labeling axes, variables, and so forth). Your memo must be submitted in a single electronic file in pdf file format. Late assignments will be penalized as described in the syllabus. Hints: Submitting an external tool Be sure to open the memo with your overall conclusions and then describe your findings and methods. Use an in-line bold face header for each section of your memo to help the reader navigate your document more quickly. • • Properly caption ALL tables and figures. • The memo should begin with this text and not directly begin with a table or figure. • Use some numbers/letters/symbols to translate between your failure modes in the FMEA table and their placement on the risk matrix. • Do not copy and paste information from the project briefing that was given to you. Treat this memo as a professional response to a supervisor who has asked you to perform some analysis. • Do not include your name. These memos are graded anonymously. • Review the scoring rubric carefully for additional guidance on the weight and importance of specific aspects of your response. ● Tasks and Questions (50 points): To receive full credit complete the tasks and answer the questions described here below: Create a reliability block diagram (RBD) of the system described in the project briefing based on the primary function of generating hydrogen gas. The RBD should be captioned as a figure. Identify and describe each of the interfaces of the system with users, maintainers, and the environment. A list or table may be helpful to organize this information. • Assemble a failure modes and effects analysis (FMEA) of the system basing your estimates of severity and likelihood on your own judgment. Display a populated risk matrix in your memo. This should be captioned as a figure. Based on your analysis, what are the failure modes that you believe are the greatest risk related to operating and maintaining the system? Memo 1 Rubric Detailed Grading Rubric The linked detailed grading rubric may offer additional guidance on how to be successful on this assignment: ENVSE 470 Expanded Memo Rubric.pdf Criteria Formatting The memo complies with all or nearly all of the provided instructions on formatting including template use, page limit, captions on figures and tables, readable and labeled figures and tables. Risk Matrix Includes risk matrix with all identified failure modes. Risk matrix is shaded to indicate acceptable and unacceptable levels of risk. Risks from FMEA are indicated with unique numbers or codes on the matrix at their appropriate coordinates. FMEA The memo includes a completed FMEA. All components are included with multiple failure modes identified for most. Failure modes are specific to the component, not generic, and described effects are consistent with the system design. Severity ratings are consistent with effects described. RBD and Interface Description Includes a reliability block diagram for the primary system function. RBD is properly formatted and includes all known system components. Correct series and parallel functional relationships are properly displayed. List or table of interfaces of system to exterior environment is complete. Risk Prioritization Memo identifies top risks from FMEA/Risk Matrix and describes them. Top risks are described in conclusions at the beginning of the memo text with citations to the FMEA. 8 pts Exemplary 5 pts Exemplary 20 pts Exemplary 10 pts Exemplary 7 pts Exemplary 7 pts Competent 4 pts Competent 8 pts Competent Ratings 5.5 pts Competent 5 pts 3 pts Developing Unsatisfactory 16 pts 12 pts Competent Developing 3 pts Developing 6 pts Developing 4 pts Developing 1 pts Unsatisfactory 5 pts Unsatisfactory 2 pts Unsatisfactory 1.5 pts Unsatisfactory 0 pt No Atte 0 pt No Atte 0 pt No Atte 0 pt No Atte 0 pt No Atte To
