DFSS - Design for Six Sigma
A Six Sigma
tool used to produce, improve and/or develop a design or process
with the objective of "designing in" 6
sigma performance enhancements and/or reducing errors or failures,
(external failures for example),
typically using a design review and then process
Any new process, procedure, or service,
should be designed with six sigma in mind in order to achieve 3.4PPM defects.
DFSS should come as the first step in many six sigma efforts. It should
make, at the very least, market to customer
requirements and DMAIC,
define, measure, analyze, improve, and control as an objective.
You can use our free software to calculate
the PPM, (parts per million), as well as Cpk,
(Process Capability), Yield and DPMO,
(Defects per Million Opportunities).

Industrialized System Part 1, (DFSS overview), Waste-Free
Industrialized System Part 2, (design tolerance), and
the Cpk vs
In the development process, can be used
when doing PDR,
(Prototype Design Reviews), and PPDR,
(Post Production Design Reviews).
