3. Introduction
• Focused methodology for carefully listening to the voice of the customer
and then effectively responding to those needs and expectations.
• Matrix product planning, decision matrices, and customer-driven
engineering
• Goal of QFD is to build a product that does exactly what the customer
wants instead of delivering a product that emphasizes expertise the
builder already has.
• QFD is achieved by linking the needs of the end user to subsystems or
specific elements of the product creation process - from design and
development to engineering, manufacturing and services.

4. Background
• QFD was created by Japanese planning specialist Yoji Akao in 1966 as a
form of cause-and-effect analysis
• QFD was brought to the United States in the early 1980s
• Gained early successes in the automotive industry
• QFD usually relate to future product plans, and are therefore sensitive,
proprietary, and valuable to competitors.

5. Processes of QFD
The idea of QFD is timing, performance evaluation, and resource commitment.
Phases:
1. Product concept planning. It starts with customers and market research with
leads to product plans, ideas, sketches, concept models, and marketing
plans.
2. Product development and specification. It would lead to the development to
prototypes and tests.
3. Manufacturing processes and production tools. They are designed based on
the product and component specifications.
4. Production of product. It starts after the pilot have been resolved
After the products have been marketed, the customer’s voice is taken again.

6. Tools of QFD
Structure is based on set of matrices.
• Main Matrix
Shows the relationship between customer requirements (WHATS) and their
corresponding technical requirement (HOWS).

7. Tools of QFD (Cond…)
House of Quality
• Widely used tool of the QFD method
• It is the nerve centre and the engine that drives the entire QFD process
• Its ability to be adopted to the requirements of a particular problems
• Its general format is made up of six major components:
o Customer requirements
o Technical requirements
o Planning matrix
o Interrelationship matrix
o Technical correlation matrix
o Technical priorities / benchmarks and targets section

9. Benefits
•Increase customer satisfaction
•Involves manufacturing in the design process
•Reduces the overall costs of design and manufacture
•Breaks down barriers between different departments.
•Focuses the design effort
•Fosters teamwork
•Reduces the number of engineering changes
•Promotes better understanding of customer demands
•Brings new design to the market faster.

10. Conclusion
• QFD does not design to replace the existing organization design process
but rather support the organization’s design process.
• Brings the customer’s voice into the production process to reduce the
unnecessary cost.
• Customers do not always explain their needs completely and accurately.
In fact, often they speak about what features they want for a product or
service. To be innovative, an organization needs to know why customers
want certain features. Understanding customer needs at this level
enables an organization to develop new solutions before its competitors
can.
