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)

Continuous Improvement Toolkit . www.citoolkit.com

 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.

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

set targets.

• QFD (Quality Function Deployment)

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?

 Consists of matrices that analyze data sets according to

the objective of the QFD process.

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.

 Typically you have

customer and technical requirements.

 Weighted scores are

assigned based on the market research information collected.

 At the roof, the

interaction between design parameters are indicated.
