Most technology development engineers use traditional reliability engi
neering methods to calibrate the objective functions of their new syst
ems to meet various marketing requirements. These methods are marginal
ly effective in reducing failure rates. To fundamentally improve quali
ty, the engineers need to focus on improving the robustness bf the bas
ic functions of their new product or process technologies and apply pa
rameter design methods to make the basic functions approach the ideal
functions under real conditions. These robust design activities should
be conducted by research and development departments before actual pr
oducts are planned. The objective is to improve the downstream reprodu
cibility of new technologies. The technical development of an electron
ic circuit is used to explain this proposition.
