3 Quality Function Deployment (QFD): A methodology for taking the Voice of the Customer. Used to translate customer requirements into product specifications or design parameters. It is often sufficient to translate the VOC into CTQs. A prerequisite to QFD is Market Research.

4 Used mainly by manufacturing companies and by some service companies. Engineering uses it to focus on significant product or service design features. Marketing uses it to determine marketing strategies. Operation uses it to identify the processes that are crucial to improving quality.

5 Also used for competitive benchmarking. Used to refine existing processes. Provides the opportunity to assess possible improvements and set targets.

6 It Answers: What do our customers need and want (VOC)? How well are we doing relative to our competitors (CA)? What technical measures relate to our customers needs (VOE)? What are the relationships between the voice of the customer and the voice of the engineer (Correlations)? How does our service or product performance compare to that of our competition (Technical Comparison)? What are the potential technical Trade-offs?

7 Consists of matrices that analyze data sets according to the objective of the QFD process. What How How Correlation Technical Requirements Whys Customer Requirements Whats & Hows Customer Importance Rating How Much Weighted Importance

8 Approach: First, list the VOC. Second, weight the importance of each statement (from 1 to 10). Third, list the CTQs. Forth, rate the strength of the relationship (use the std. symbols). Finally, add up the weighted scores for each CTQ to establish which should be given highest priority. What / VOC Customer Requirements How / CTQs Technical Requirements Whats & Hows Weighted Importance

9 Typically you have customer and technical requirements. Weighted scores are assigned based on the market research information collected.

10 At the centre is the interaction matrix. At the roof, the interaction between design parameters are indicated.
