During this past week, I observed how the classic Six Sigma improvement methodology has evolved into the Six Sigma perfection methodology called Design for Six Sigma (DFSS). By listening to the voice of the customer at the design stage, DFSS aims to eliminate the need for any foreseeable improvements to products, process, and services. It was particularly interesting to learn about Design for X (DFX) and how I felt it echoed Dr. Deming’s theory on appreciation of a system. Concurrent engineering the catalyst behind the DFX methodology emphasizes the involvement of all functions and disciplines in the design stage. This level of involvement only indicates the appreciation of the system as a whole rather than individual functions working in isolation.
Classic Six Sigma methodology relies on a hierarchal structure to drive its implementation which often causes resentment of the initiative and has been suggested to be one of its limitations. DFSS aims to overcome this problem by involving all concerned stakeholders with the aim of better understanding the voice of their customers and the voice of their business. There are loads of other interesting elements of DFSS and DFX that I am now aware of and would love to share. However it’s been a long weekend and a longer day particularly for me. GOODNIGHT…..
