Another flavor of the DMADV methodology is DMADOV, that is, Design, Mea-
sure, Analyze, Design, Optimize, and Verify. Other modified versions include DCCDI
and DMEDI. DCCDI is being pushed by Geoff Tennant and is defined as Define, Cus-
tomer Concept, Design, and Implement, which is a replica of the DMADV phases.
DMEDI is being taught by PriceWaterhouseCoopers and stands for Define, Measure,
Explore, Develop, and Implement. The fact is that all of these DFSS methodologies
use almost the same tools (quality function deployment, failure mode and effects
analysis, benchmarking, design of experiments, simulation, statistical optimization,
error proofing, robust design, etc.) and provide little difficulty in alternating using
them. On top of these common elements, the ICOV offers a thread through a road
map with overlaid tools that is based on nontraditional tools such as design mappings,
design axioms, creativity tools, as well as cultural treatments.
A DFSS approach can be mapped closely to the software development cycle as
illustrated in the development of a DVD player (Shenvi, 2008) from Philips, where a
reduction in cost of non quality (CONQ) is attempted using a DFSS approach. The
case study is summarized in Appendix 8.A.

SUMMARY
Software DFSS offers a robust set of tools and processes that address many of today's
complex business design problems. The DFSS approach helps design teams frame
their project based on a process with financial, cultural, and strategic implications
to the business. The software DFSS comprehensive tools and methods described in
this topic allow teams to assess software issues quickly and identify financial and
operational improvements that reduce costs, optimize investments, and maximize
returns. Software DFSS leverages a flexible and nimble organization and maintains
low development costs allowing deploying companies to pass these benefits on to
their customers. Software DFSS employs a unique gated process that allows teams to
build tailor-made approaches (i.e., not all the tools need to be used in each project).
Therefore, it can be designed to accommodate the specific needs of the project charter.
Project by project, the competency level of the design teams will be enhanced leading
to deeper knowledge and broader experience.
In this topic, we formed and integrated several strategic and tactical and method-
ologies that produce synergies to enhance software DFSS capabilities to deliver a
broad set of optimized solutions. The method presented in this topic has a widespread
application to help design teams and the belt population in different project portfolios
(e.g., staffing and other human resources functions; finance, operations, and supply
chain functions; organizational development; financial software; training; technol-
ogy; and tools and methods)
Software DFSS provides a unique commitment to the project customers by guar-
anteeing agreed upon financial and other results. Each project must have measur-
able outcomes, and the design team is responsible for defining and achieving those
outcomes. Software DFSS ensures these outcomes through risk identification and
mitigation plans, variable (DFSS tools that are used over many stages) and fixed
