Quality Function Deployment (QFD)
A Means of integrating the design process– Voice of the Customer– Priorities of Marketing– Product design knowledge of the Engineer– (Production Planning and Design)

Building a House of Quality
Gather customer attributes (in the words of the customer)
Group attributes logically Assess relative importance of the attributes

Building a House of Quality (2)
Assess competitive performance on the attributes
Describe product in terms of engineering characteristics
Detail influence of engineering characteristics on customer attributes
Detail interaction between engineering characteristics

Using the House of Quality
Prioritize on attributes that we do poorly on, or where we might increase our lead
Determine what engineering characteristics strongly influence the desired attribute
Check for adverse interactions and weigh tradeoffs Set target levels (not ranges) Link to lower level houses
– Parts characteristics– Key process operations– Production requirements

Problems With QFD
Matrix is too large– Prioritize on important attributes– Analyzes independent subsystems
independently Customer priorities not clear
– Consider segmenting market

Problems With QFD (2)
Customers’ stated preferences and actions differ– Use revealed preference techniques if you
suspect a problem QFD is messy
– Not QFD, but rather the interaction between diverse groups is cause
– Stick with it, the results are worthwhile
