Yoji Akao is widely regarded as the father of QFD and his work led to its first implementation at the Mitsubishi Heavy Industries Kobe Shipyard in 1972. The interest in QFD in the West was stimulated by reports of the achievements made by Toyota through its application between 1977 and 1984. These included a reduction in product development costs by 61%, a decrease in the development cycle by one third and the virtual elimination of rust related warranty problems
Yoji Akao defined QFD as "a method for developing a design quality aimed at satisfying the consumer and then translating the consumer's demands into design targets and major quality assurance points to be used throughout the production phase" .
The "House of Quality" matrix is the most recognized form of QFD. It is utilized by a multidisciplinary team to translate a set of customer requirements, drawing upon market research and benchmarking data, into an appropriate number of prioritized engineering targets to be met by a new product design. There are many slightly different forms of this matrix and this ability to be adapted to the requirements of a particular problem or group of users forms one of its major strengths. The general format of the "House of Quality" is made up of six major components which are completed in the course of a QFD project
QFD method uses cascading Houses of Quality Voice of the customer Customer Requirements Part Characteristics Engineering Characteristics Process Characteristics Product Planning Part Design Process Planning Production Planning Production Characteristics
The QFD process uses matrices to help the organization to satisfy their customer requirements ( which are a structured list of requirements derived from customer statements).
The first of these matrices is called the house of quality (HOQ).
It displays the customer wants and needs along the left side of the matrix and the technical requirement (which are a structured set of relevant and measurable product characteristics )to meet these wants along the top of the matrix
The U.S. institute dedicated to the advancement of Quality Function Deployment. The institute organizes forums and seminars, holds an annual symposium to publicize the latest QFD applications and administers the Akao Prize .
The International Council for QFD (ICQFD) aims to promote a united international effort in the development of QFD techniques. The council organizes international conferences on QFD and promotes QFD research .
