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.

- QFD (Quality Function Deployment)


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 thatare crucial to improving quality.



Also used for competitive benchmarking.

Used to refine existing processes.

Provides the opportunity to assess possible improvements and set targets.



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 compareto that of our competition (Technical Comparison)?

What are the potential technical Trade-offs?



Consists of matrices that analyze data sets according tothe objective of the QFD process.

Approach:

First, list the VOC.

Second, weight the importance of eachstatement (from 1 to 10).

Third, list the CTQs.

Forth, rate the strength of therelationship (use the std. symbols).

Finally, add up the weighted scores foreach CTQ to establish which shouldbe given highest priority.
