House of quality is an approach in which customers use product prototype versions and provide feedback to developers.
The House of Quality (HoQ) approach is a fundamental component of Quality Function Deployment (QFD), which is a structured method for defining customer requirements and translating them into specific plans to produce products to meet those needs. It acts as a comprehensive summary diagram that integrates the voice of the customer (VOC) into the product design phase, ensuring that products are designed to reflect customers' desires and tastes. The HoQ is visualized as a matrix that helps teams convert customer demands into technical descriptions, which are used to guide the development process. This tool is instrumental in ensuring that customer requirements are the focal point of product development, thereby facilitating better and more informed decision-making. By doing so, the House of Quality aids organizations in aligning their products with market demands, enhancing customer satisfaction, and promoting internal collaboration among marketing, design, and manufacturing teams.
