DMAIC and DMADV
In contrast to Six Sigma, the Design for Six Sigma methodology does not actually design a new part or process due to the fact that every enterprise constitutes of unique design processes which are tailored to their own products or services. However, it is imperative to note that DFSS can make these processes more robust and feasible. DFSS aims to deliver products and processes that perform at higher quality levels than otherwise possible. In brief, whilst DMAIC can be generally characterized as a find-and-fix methodology, DFSS could be thought of as a preventive one.
