Quality Function Deployment - 
 
A  method  used  to  translate  voice  of  the  customer  information  into  product  requirements/CTQs  and  to  continue  deployment   (for  example,  cascading)  of  requirements  to  parts  and  process  requirements. This is also called as House of Quality.

QFD Deployment Process
 
Level A - Customer Requirements vs. Design Features
 
•          Gather customer requirements for all types of customers.
•          Specify performance level desired and achieved.
•          Provide competitive assessment of features and functions.
•          Relate customer requirements to design features.
 
Level B - Design Features vs. Part Characteristics
 
•          Specify how to deliver design features.
•          Identify critical performance factors.
•          Link design features to specifications.
•          Track development of design maturity.
 
Level C - Part Characteristics vs. Process Characteristics
•          Specify part features.
•          Set critical parameters.
•          Fix part tolerances.
•          Establish control limits.
Level D - Process Characteristics vs. Operating System
 
•          Identifies supplier control plan.
•          Identifies special test equipment.
•          Specifies work instructions.
•          Identifies operator training requirements.
