DFSS (Design for Six
Sigma) is used to design a
new process, product or service, or to redesign
an existing process, product or service
from scratch. This contrasts with the normal
Six Sigma approach that is used to improve
existing processes, products or services.
For example if you wanted to replace a
manual accounting system with a computer-based
one then you might use DFSS.
Design For Six Sigma uses the DMADV
or DMADOV sequence
rather than the DMAIC
Methods used in Design for Six Sigma include
Five Forces Analysis, Pugh
and the Taguchi
Approach to the Design of Experiments.
