Quality Function Deployment is a methodology developed by Dr. Yoji Akao. The methodology attempts to accomplish all major requirements of the customer. It does this by identifying the voice of the customer and working to ensure the needs are met or exceeded. QFD is also often viewed as a set of communication and translation tools. QFD tries to eliminate the gap between what the customer wants and what they get.
