Dr. Parmigiani, I thought I'd send you a message and let you know where I've ended up since college… … As you may recall I took senior project from you a few years back and did the human powered vehicle project … …Since I left I know that you've moved towards a fusing of industrial and mechanical engineering. My experience so far supports that move as I am constantly required to think of how the parts will be made and how they will fit into to our stream of labor and lean manufacturing etc. In a constant push to make more things faster,without sacrificing quality (and who wouldn't want that) I find myself more concerned with process improvements than product improvements and also more excited about them… Brendan Treacy Renovo Hardwood Bicycles ME Senior Project

Open minds. Open doors. TM House of Quality Overview Provides a concise diagram of project requirements Constructed in three parts in this course Part 1: CRs & Weightings Part 2: ERs & Targets/Tolerances Part 3: Testing Plans & Design Links Part 1: Done (but can be changed this term w/out petition, just get signatures) Part 2: Next Status meeting 2 (draft to discuss) Progress report 2 (revised draft, hand-in for review) Preliminary Proposal (final version, with signatures)

Open minds. Open doors. TM Customer Requirements (CRs) A complete listing, in the “language of the sponsor”, of what must be done Each CR deals with one concept (e.g. don’t group “Small” and “Lightweight”) Example: “Device must be lightweight” One sponsor requirement may generate several CR’s (e.g. “Portable”) Must be approved by team, sponsor mentor, faculty advisor, course instructor Project scope defined in CR's... pay close attention! Weightings Indicate relative importance of each CR (greater weighting  more important) Total of 250 points to distribute among CRs (i.e. sum of all weightings = 250) Example: “Device must be lightweight” given weighting of 50. Low Technical Effort (LTE) CRs: Not given numerical weighting, but must be met. Must be approved by team, sponsor mentor, faculty advisor, course instructor Very important in grading Evaluation 1 and Evaluation 2 in winter term House of Quality Part 1: Done … … if you now see problems, correct in Part 2 when ERs & TTs are added… … if you now see problems, correct in Part 2 when ERs & TTs are added…

Open minds. Open doors. TM Engineering Requirements (ERs) Define CRs in terms of technical, measurable specifications Generated from Customer Requirements (One CR may generate several ERs) Ex.: CR “Device must be lightweight” maps to ER “Weighs less than 20 lb” Used in specifying and evaluating design concepts Must be approved by team, sponsor mentor, faculty advisor, course instructor Ability to properly test and satisfy ERs constitutes 50% of winter term grade Customer Requirements WeightingPenalty E1 Score E2 Score Engineering Requirements (ER's) CR's Target (w/ tolerance) Testing Procedure (TP#) Design Link (DL#) Approval (print name, sign, and date): Team member 1:Faculty Advisor: Team member 2:Sponsor Mentor: Team member 3:Course Instructor:

Open minds. Open doors. TM Target (w/ tolerance) The Target is the design-to value for an ER (value to use in calculations) The Tolerance (+/- value, <>, etc.) defines the amount of permissible variation Example: ER “Weighs less than 20 lb” has Target “15lb”, Tolerance “<20lb” ER satisfied if test result = target value within tolerance Must be approved by team, sponsor mentor, faculty advisor, course instructor Don’t use the extreme-permitted ER value as the design-to value!
