Design for Six Sigma (DFSS) is a method that helps companies create high-quality products that meet customer needs. By using tools like Quality Function Deployment (QFD) and House of Quality (HOQ), companies can identify what customers want and design products to exceed their expectations. Research shows that focusing on key quality characteristics and customer requirements early in the design process leads to successful products. Gathering different types of customer feedback, both measurable and subjective, is crucial for designing products that satisfy customers. By following a systematic approach to QFD, companies can ensure customer satisfaction and bring innovative products to the market quickly.
