1. Design – Chapter 1 Is not research! Verb: invent, intend, devise Noun: drawing, arrangement, pattern, plan, pattern, art of making designs Involves devices, processes, re- engineering, systems, optimization, regulations, finances, innovation, invention, entrepreneurship, etc.

2. Basics Who? What? #### Where? When? Why? How? Your job.

3. Design: National Academy of Science Product refers to hardware, service, or mission. Process refers to the means by which a product is manufactured and supported Development refers to the refinement of products and processes to correct problems. (Re-engineering, sometimes reverse engineering, …)

4. Design: NAS 1.Mission requirements analysis/Product system strategy - high level engineering analysis - requirements definition

5. Design: NAS 2.Product specification - product strategy - voice of the customer!!! (QFD, etc.) - environment (EPA) & regulatory (FDA!!!) - planned product specification

6. Design: NAS 3.Concept development - target setting (cost, schedule, performance, etc.) - brainstorming on product & process alternatives - development of product and process concepts.

7. Design: NAS 4.Preliminary Product and/or Process design - high level definition of product and process designs - evaluation of same v. targets - high level system trade-offs

8. Design: NAS 5.Refinement & verification of detail product and process designs - development of designs for components, subsystems & manufacturing - Geometry creation - prediction & evaluation of attributes - tracking & trade-offs

9. Design: NAS 6.System Prototype Development - experimental evaluation of attributes that do not meet target values 7.Preparation for production - refine process for manufacture 8.Production, Testing, Certification, Delivery 9.Operation, support, decommissioning, disposal

10. Not mentioned Retracing if problem ill defined Excessive documentation Human patients, animal studies, permissions Design is often iterative Delving into already patented info bases Teamwork, finances, reality Watch Junkyard Wars – Wed PM

11. Fundamental Design Tools Chapter 2 Paul King

12. Brainstorming Five to fifteen individuals Discussion leader restates problem and reiterates rules of discussion Individuals suggest ideas Evaluate ideas at conclusion of discussion Useful for new ideas / deadlock Drawback: relies on willingness to speak up

13. Class Design Problem Ear Wax

14. Method 635 Six individuals Each individual writes down three ideas Tablets are exchanged and the ideas are elaborated on or new ideas are generated Five exchanges take place Useful in its systematic approach and large numbers of ideas Drawback: isolation, no group synergy

15. Delphi Model Polling process Expert panel generates starting points Suggestions are regrouped and returned to panelists Resultant response list is reordered and evaluated Useful in situations where future of process is of concern Drawback: relies on high response rate

16. Synetics Problem is presented to a small group Group familiarizes itself with the problem Analogies of terms are examined and relationships forced Useful when problem to be solved has an analogy and group is willing to explore bizarre trains of thought

17. Class Design Example Right to left heart shunt that needs to be closed – minimally invasive technology. When doing catheterization, need to go with the flow… Cannon drops when rapidly fired. Need to get a ladder through a small space and up in an alleyway.
