Quality Function Deployment (QFD) is a methodology systematized by Dr. Shigeru Mizuno and Dr. Yoji Akao in 1978. In QFD, customer needs and expectations are first refined, and then refined information is reliably transferred into the product and service development process. With this, QFD can give some opportunities to improve the quality of products and services. Today, QFD is used by many companies and organizations in Japan and abroad, and QFD is a methodology that Japan is proud of, which has enabled it to provide products and services with high customer satisfaction.
