Design For Six Sigma (DFSS)  Design For Six Sigma (DFSS)  When
people talk about Six Sigma, they usually are referring to the
DMAIC (define, measure, analyze, improve, control) methodology,
which is used for optimizing an existing product or process,
which may not be meeting customer needs or specifications.
Design For Six Sigma, or DFSS, is quite different from DMAIC, as
it is used for designing a completely new product or process
that meets customer specifications. Compared to DMAIC, which is
universally applicable on any business process, DFSS concepts
and techniques do not have universal recognition.  They vary
from company to company, depending on the basic characteristics
of the product of business process that needs to be developed.
DFSS may either be implemented for improving the work culture
within an organization, or for assisting in the deployment of
other Six Sigma concepts that are being used by competitors.
This makes DFSS a more approach-based methodology, rather than a
standalone optimization
