Uncovering differences and similarities among quality function deployment-based methods in Design for X: Benchmarking in different domains

The ability for a product or a service to meet customer needs and requirements efficiently before its market launch is a key-point in design and development activities. Quality Function Deployment (QFD) represents one of the most powerful design methods to achieve such a goal. This study investigates the QFD-based methods proposed in the last two decades, whose use in different ambits of Design for X (DfX) is reported to be effective. We selected most common QFD-based methods, analyzing how designers can implement and coordinate them in design activities effectively throughout their application to an identical case study.
