【正文】 dy to Test QFD ? “The major problem with HoQ is the way in which the attribute relations are established with arbitrary scales” ? “…it has been suggested that the use of such scales is no better than using a random number generator. Evidence of this is offered in the case study…” Olenwik, A. T. and K. E. Lewis, 20xx “On Validating Design Decision Methodologies”, ASME Design Engineering Technical Conference, DETC20xx DTM48669. A Case Study to Test QFD ? The total bination of number scales (from 1 to 9) were found. Examples include (1,3,9), (2,4,6),(1,2,3) etc. and are always in the form abc. ? Next, random numbers taken from a uniform distribution from 1 to 9 were inserted where ever a relationship was found to exist. ? The relative weights were calculated for the 84 cases. Olenwik, A. T. and K. E. Lewis, 20xx “On Validating Design Decision Methodologies”, ASME Design Engineering Technical Conference, DETC20xx DTM48669. A Case Study to Test QFD Olenwik, A. T. and K. E. Lewis, 20xx “On Validating Design Decision Methodologies”, ASME Design Engineering Technical Conference, DETC20xx DTM48669. “ttests show that the null hypothesis is not false for all the engineering attributes except balance and volume” “Certainly, the results generated here should raise some concerns about the use of HoQ as a design tool.” Using Matlab to Check Results ? Input data (put into matrix M) Using Matlab to Check Results “Scales” Using Matlab to Check Results “Random” Comparing Results of “Scales” and “Random” A Case Study to Test QFD ? “The major problem with HoQ is the way in which the attribute relations are established with arbitrary scales” ? “…it has been suggested that the use of such scales is no better than using a random number generator. Evidence of this is offered in the case study…” Olenwik, A. T. and K. E. Lewis, 20xx “On Validating Design Decision Methodologies”, ASME Design Engineering Technical Conference, DETC20xx DTM48669. No, they are very different from a random number generator No, they are not arbitrary Quality Function Deployment Summary ? “…can break down functional barriers and encourage teamwork …” ? “The house relives no one of the responsibility of making the tough decisions” ? Many of the most effective panies use QFD ? Surveys suggest that QFD provides long term petitive advantages ? The arguments against QFD so far seem weak Plan for the Session ? What is rationality? ? Quality Function Deployment –What is it for? What is it not for? –What is it? How do you use it? –Does it work? ? Next steps Next Steps ? Optional Matlab session 11AM Fri 3449D ? Do the reading assignment –Pugh_Total Design ? If you have not done the exam –Do the exam by 7:30AM Tues 29 June –Respect the 2 hour limit and “one sitting” rule ? If you have done the exam –Please refrain from discussing the exam ? Do assignment 3 Assignment 3 QFD ? Self select into teams of 3 to 5 people ? Heterogeneous teams preferred 1. Select a system of interest to you (or a subsystem) and develop a HoQ(~10X10) 2. Take a small subset (~ 2X2) and create at least three linked houses ? Write an essay on an alternative to QFD
