Similarities With Other Methods
Arguments about what makes DFSS different from Six Sigma demonstrate the similarities between DFSS and other established engineering practices such as Probabilistic design and design for quality. In general Six Sigma with its DMAIC roadmap focuses on improvement of an existing process or processes. DFSS focuses on the creation of new value with inputs from customers, suppliers and business needs. While traditional Six Sigma may also use those inputs, the focus is again on improvement and not design of some new product or system. It also shows the engineering background of DFSS. However, like other methods developed in engineering, there is no theoretical reason why DFSS can't be used in areas outside of engineering.

Famous quotes containing the words similarities and/or methods:
“One internationally known twin researcher sees similarities between twins’ relationships and those of couple who have been married a long time. Fifteen-year-old twins, as well as spouses approaching their fortieth anniversary, each know their partners’ likes, dislikes, habits, and idiosyncracies as well as they know their own.”
—Pamela Patrick Novotny (20th century)
“I think it is a wise course for laborers to unite to defend their interests.... I think the employer who declines to deal with organized labor and to recognize it as a proper element in the settlement of wage controversies is behind the times.... Of course, when organized labor permits itself to sympathize with violent methods or undue duress, it is not entitled to our sympathy.”
—William Howard Taft (1857–1930)
