Quality function deployment (QFD) is a technique that involves translating customer needs or requirements into product features or specifications. QFD helps to relate the product features to customer value by using a matrix called a House of Quality, which shows how each feature satisfies a customer requirement, how important each requirement is to the customer, how well each feature performs compared to competitors, and how each feature affects other features. QFD can also help to identify gaps or opportunities for improvement in the product design.
