Risk Assessment• Risk: Patient cannot move naturally while using system

• Would adulterate reported data• Reviewed results with Customer and Advisor• Mitigated during design phase by making people’s movements a design

concern

• Risk: Testing phase does not occur under realistic circumstances• Enclosures would not survive ‘real’ conditions• Exposed enclosures to expected usage• Mitigated by testing beyond overloading test conditions upon completion to

find approximate factor of safety.

Risk Assessment

• Major Risk: Interfaces do not stay on patient• Sensor package reports useless data

• Solution• Careful attention paid to making the system viable for

patients with many body types• Mitigated by delivering multiple attachment styles

Risk Assessment• Risk: Lack of communication between P10010 and

P10011• Incomplete Design• Failure to explore possibilities completely• Mitigated by ensuring regular between groups and/or bi-weekly

meetings

Success Evaluation• Areas of success:

• Designed functional prototype• Tested several attachment techniques• Documented all results for future team

• Areas of lack of success• Flex sensor implementation

Joe Piehler• Punctual

• Attended all relevant meetings, on time• Prepared to work on arrival

• Thorough and Accurate • Test plan results recording• Majority of paper writing and proofreading

• Communicative • Always available by text or e-mail

• Professional and Ethical • Dedicated

• Never asked more of the team than I was willing to do myself

Joe Piehler• Test Plan

• Designed majority of tests• Carried out many tests individually• Designed and updated results of testing

• Project Plan• Updated as needed

• Wrote majority of final paper

Dan Shields• Punctual

• Always attended meetings• Attended associated presentations when possible

• Thorough and Accurate • Communicative

• Hard to reach by email• Professional and Ethical • Dedicated

• Underestimated project complexity• Overestimated my own productivity• I hate the flu• Stubbornness and Vindication Trap

Dan Shields• Acquired materials• Pursued Informed suggestions for attachments• Performed concept testing• Lead attachment• Testing of enclosures

Alex Frechette• Punctual

• Always made necessary meetings• Not always present for Fridays, my work was complete for what the

testing team needed on Fridays when testing was completed• Thorough and Accurate

• Comprehensive manufacturing plan• Manufactured quality hard enclosures

• Communicative • Easily assessable through email and phone

• Professional and Ethical • Dedicated

Alex – MSD I Lessons Learned UniGraphics NX Software Pushed to order materials at end of MSD I Paid more attention to Material Selection

Polyethylene was chosen during BOM stage based on price and availability

Learned importance of the design process and documents Project plan, selection process,

Ask questions during design process Easier to ask questions early then make changes later

How to work as a team to complete deliverables

Alex – MSD II Lessons LearnedPlan accordingly to meet deadlines for teamParallel Manufacturing and testingValue of finding the right toolsPolyethylene poor machining propertiesDelrin is a much better choiceCommunication with P10010 Overall, learned how valuable the design process can be

Dan - Lessons Learned• Overextended• 80% confidence

• 20% whispering doubt, saying do more testing

• Communication• Give honest critique• Speak Up• Reinforce Others

• Limits• Organized Planning

Joe – MSD I Lessons Learned• Communication• Recording information• Risk Assessment and Project Plan• More expertise needed earlier• Tradeoffs between academic and practical goals• Effectiveness of Design Process

Joe – MSD II Lessons Learned• Communication!• Sliding scope of project• Facility Contingency• Earlier Flex testing
