品質機能展開（QFD）

Quality Function Deployment (QFD) is a structured approach used in product design and development that translates customer requirements into specific technical features and specifications. It employs a series of matrices, commonly known as the House of Quality, to facilitate communication among cross-functional teams and ensure alignment between customer needs and engineering capabilities. By prioritizing features based on customer value, QFD helps streamline the innovation process and enhances overall product quality and market competitiveness.
