Read more ยปSoftware Quality Function Deployment
Published:Quality function deployment (QFD) is a process used to determine product development characteristics that combine technical requirements with customer preferences. Using an integrated matrix known as the “house of quality,” QFD considers the different influences bearing on the design to promote concurrent engineering, resulting in increased product acceptance. The basic QFD methodology can also be […]
