  1. Risk Analysis Proposal Suggestions

  2. Price and memory are of equal importance. Which thumb drive would you pick?

  3. Which thumb drive would you pick? Sources : J.C. Musto, The Influence of the “Decoy Effect” on the Engineering Design Process, 2012 ASEE Conference proceedings, AC 2012-5240 Wikipedia: Decoy Effect

  4. Decoy effect says A and Y will be picked more often.A and Y are targets and C and Z are decoys.

  5. Engineering design is a decision making process • Select design solution from a set of alternative designs that meets performance specifications and is optimal • Similar alternatives could introduce a decoy effect and lead engineers to select a design that is better than similar alternativesbut not the best overall • Decision matrix can effectively mitigate decoy effect

  6. Risk Management - Analysis What could possibly go wrong here? Actual Product from 1946

  7. How do we responsibly assess risk? • Risk assessment describes the nature and magnitude of a risk • Should you put a lightning rod on a lawnmower? • Low probability requirements could result in overdesign • How about “paper-cut-proof” paper? • High probability of occurrence could be perceived as negligence • Good designs have low risk Frequency (# events/unit time) Magnitude (Consequence/event) Risk

  8. Cost-benefit analysis examines the cost of different alternatives to achieve a defined acceptable level of safety COMPANY Costs ($, lives, PR, etc…) CUSTOMER / PUBLIC Benefits ($, lives, PR, etc...) Good designs have a low cost-benefit ratio.

  9. The Ford Pinto is a good example of cost–benefit analysis. • $11/car to fix fuel system problem or a total of $137M • National Highway Traffic Safety Administration estimated 180 accidents • Ford originally estimated $200K/death or about $50M for all of the accidents • What are the ethical implications here?

  10. What factors should we take into account in risk management? Technical Marketing / PR Manufacturing Reliability Schedule

  11. Come up with a risk plan to minimize risk to an acceptable level. It helps reduce the number of surprises later.

  12. Simple Risk Plan Example: A Travel Mug Actions to minimize risk Fall Back Strategy Risk Risk Level Coffee spill in lap High Improve lid fit Change cup design Scald mouth Add note that coffee is hot Moderate Limit pot temperature Cut lip on edge of cup Change lid design Monitor quality of cup mfg. Low

  13. An alternative risk management tool is the likelihood-consequence diagram. Negligence e Often used in government/military project risk assessment. d c Likelihood Overdesign b Usually accompanied by an actions table as shown on the previous slide. a 5 4 3 2 1 Consequence

  14. What are some guidelines to use during risk analysis? Consequence Likelihood

  15. Simple Risk Plan Example: A Travel Mug e Scald mouth d A C c Likelihood Spill coffee in lap b B a 5 4 3 2 1 A risk mitigation table would follow this diagram. Cut lip on edge of mug Consequence

  16. You should anticipate stupid use. Careless use is not grounds for absolving the manufacturer or engineer of liability "a common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.“ - Douglas Adams

  17. There are other ways to minimize risk to the company. • Tort or low caps on liability • Insurance • Voluntary Standards followed • Gov’t Codes and Regulations followed How much is a human life worth? Risk-benefit and how much compensation for a life? 1992: $150,000 – 70-79 old single woman $2,100,000 – 30-39 old married man Today: averages ~$6-8 million MUST also consider engineering ETHICS when evaluating human life

  18. Design by Committee and Scope Creep • http://www.youtube.com/watch?v=Wac3aGn5twc

  19. Constant communication with your project sponsor is critical “… two in five projects do not meet their original goals and business intent, and one-half of those unsuccessful projects are related to ineffective communications.” - http://www.pmi.org/learning/thought-leadership/pulse That’s 20% failure due to communication!

  20. Proposal Pitfalls to Avoid

  21. Proofreading, grammar, and spelling are critical. • Follow all requirements in last 2 pages of Report Template • Cut through the “BS”: • Each sentence and paragraph should have a specific purpose • Be precise and concise • Do not use first person or pronouns in a technical document • “He said we should use it.” • One sentence does not constitute a paragraph • Sentences have defined structure • Nouns and verbs are required.

  22. Proofreading, grammar and spelling are critical. • Use proper English. Your reader may be from another part of the country or world. • Do not use local slang in written reports. • “needs removed”  “needs to be removed” • Do not use contractions in formal writing • “don’t”  “do not” • Acronyms should be defined the first time used but only if the acronym is actually used later • “Nobody likes getting audited by the Internal Revenue Service (IRS).”

  23. Use the same format for all figures/tables. • Use MS Word’s “References”, “Insert Citation”, “Insert Caption”, and “Cross Reference” tools. • Do not use “tight” text wrapping around figures or tables. Set each figure on its own line with the caption centered below figures and above tables. • Use MS Word’s “Style” capabilities. If setup and used properly, these will save you frustration. • Do not insert tables as pictures in MS Word. They are not editable, come out looking blurry and are hard to read.

  24. Additional notes for formal writing • If you include a reference in your “References” section, you need to cite it in the text. • Keep consistent unit system through the report • You can use multiple units with parentheses. • “The part was 25.4 mm (1 in.) long.” • Always put the same unit system in parentheses.

  25. Here is an example of a good figure and caption. No title if you have captions. It is redundant. Axes labeled with units if appropriate Fig. 1: Sound pressure background levels Figure number

  26. Here is another example of a good figure and caption. Multi-part figure should have identifying letters Fig. 2: Photos of p-a vector sensors construction

  27. Here is an example of a good table and caption. Table 3-2: Decay rate and reverberation parameters for ARL reverberation tank Caption is above the table Headers have units Row/column shading can help to make table more readable
