(2) Major activities in IDOV steps
In Figure 2.6, we see a typical DFSS process and the IDOV
steps. The major activities and methodologies used in each
step can be found in Figure 2.7.
Figure 2.6. A typical DFSS process
There are several problems to be tackled for DFSS imple-
mentation. These problems must be solved for a smooth intro-
duction of DFSS. They are as follows.
1) Researchers tend to resist introduction of any new sci-
entific methodology into their research activities.

Hence, their understanding and cooperation or
approval should be sought before introducing the
DFSS into their activity.
2) GB or BB education/training is especially necessary,
since there are many scientific tools for R&D including
QFD, DOE, simulation techniques, robust designs and
regression analysis. For such education/training, text-
books that contain real and practical examples should
be carefully prepared in order to make researchers
understand why DFSS is a very useful tool.
