4.3 THE FUTURE

TheDFSSroadmapisstillevolving.Forexample,inApril2004,theSixSigmacorporate
vice-president of GE (the originator of DFSS), Piet van Abeelen, announced that “The
roadmap for DFSS at GE is now DMADOV, with measurements and optimization
steps strictly enforced. Because of the nature of the newly re-defined DMADOV, it is
used for new product introduction or large enterprise-wide processes.” New systems
engineering methodologies for DFSS are still being proposed and tested in practice.
Other multinational corporations such as Philips and Siemens are still trying to adapt
the principles of DFSS to their existing product development process. It is thus natural
for the roadmap to keep evolving over time as innovation is the key driving force in
any design-oriented enterprise.
