still in the research lab. This robust design must be a dynamic design
that focuses on improving its main, generic function. The ideal func-
tion has to be carefully selected in order to build robustness into the
main transformation process that underlies the high-level function.
In a regular lab environment, there are very few noise factors.
Robust technology development study will artificially bring many
noise factors into the environment. Design and redesign will take
place for the new technology until robustness in functional perfor-
mance against noise factors is achieved.
If a new technology is “tested out” in the lab for many potential noise
factors, its success in future products and production will be greatly
improved.
