The "House of Quality" is a visual tool used in Quality Function Deployment (QFD) to translate customer requirements into technical specifications. It helps teams prioritize features based on customer needs, ensuring that the final product aligns with what users want. The structure resembles a house, with different sections representing various aspects of the product development process. In the House of Quality, customer requirements are listed on one axis, while technical requirements are on the other. The relationships between these two sets of requirements are mapped in a matrix format, allowing teams to identify critical areas for improvement and focus their efforts effectively.
