As mentioned in the Importance section of this brief guide, QFD is a more proactive approach in such a way that it aims to incorporate customer feedback during the initial stages of production and manufacturing processes. Also, most quality initiatives focus on minimizing or eliminating errors—human or machine-made—to produce maximum results and achieve zero defects. Unlike other quality management tools, QFD takes the extra step to ensure that design processes capture customer requirements—underlying or stated—toward positive experiences and valuable offerings.
