QFD and Design for Six Sigma: A Quality Product Development System
In today's fast-paced global economy, time to market constraints are demanding that companies produce
their products more quickly and with higher quality. This has driven a shift from inspection
based quality where defects are found and repaired, to design based quality where defects
are prevented from ever occurring. Through QFD, design of ex-periments, detailed failure
mode analyses, and other quality tools, zero defect or 3ppm defect levels are
being achieved by design. This is called Design for Six Sigma (DFSS).
Even greater gains can be made from DFSS when it is combined with QFD to assure not just an
absence of defects, but true value as defined by the customer. QFD helps the DFSS team find
critical, unmet customer needs and assure they are designed into the product and supported
throughout the manufacturing and assembly process. We could call this Customer Driven DFSS.
This paper will show how the goals of DFSS can be achieved and surpassed through the
complimentary usage of QFD.
