2. QUALITY FUNCTION DEPLOYMENT (QFD) Quality Function Deployment (QFD) is an approach to design introduced in Japan in 1966 by Yoji Akao.
3. Dr. Akao is a professor of industrial Engineering at Tamagawa University in Tokyo and is one of the foremost leaders in the TQC movement in Japan. He has long led and participated in many of the key research committees of the Union of Japanese Scientists and Engineers (JUSE), the Japanese Standards Association (JSA) and the Japanese Society for Quality Control (JSQC)
4. Why QFD? A lack of well defined product development processes in research and design can be the root cause for the ruination of a company. To have a successful product, we must understand user needs.
5. Why QFD? QFD provides a formal process to understand user needs and to weave these needs across the entire product development cycle including manufacturing.
6. DEFINITION OF QFD QFD is a very systematic and organized approach of taking customer needs and demands in the consideration when designing a new products and services or when improving existing products and services.
