Quality function deployment (QFD) is a method to translate customer needs into technical requirements for new product development. It uses a "house of quality" diagram to relate customer needs with engineering specifications. QFD was developed in Japan in 1966 and helps prioritize product characteristics based on customer feedback to guide design and testing. It has been applied to many industries and is part of the ISO 9000 quality standard. Benefits include improved customer satisfaction, production efficiency, and decision making through a systematic process of capturing the voice of the customer.

 QFD is designed to help planners focus on characteristics
of a new or existing product or service from the
viewpoints of market segments, company, or
technology-development needs.
 QFD helps transform customer needs (the voice of the
customer [VOC]) into engineering characteristics (and
appropriate test methods) for a product or
service, prioritizing each product or service characteristic
while simultaneously setting development targets for
product or service.

3. History
 Dr. Yoji Akao of Japan developed quality function
deployment (QFD) in 1966.
 House of quality is a subset of QFD.
 QFD was first introduced in USA and Europe in 1983.

4. Areas of application
 Wide variety of services, consumer products, military
needs (such as the F-35 Joint Strike Fighter), and
emerging technology products.
 Identify and document competitive marketing
strategies and tactics
 QFD is considered a key practice of Design for Six
Sigma.
 Included in ISO 9000:2000 standard, customer
satisfaction.

5. House of quality
 House of Quality appeared in 1972 in the design of an oil
tanker by Mitsubishi Heavy Industries.
 House of quality graphically articulates the means by
which it will achieve customer requirements.
 When fully constructed, house of quality takes shape of
a roofed house and that's why the name- house of
quality.
