Most experimental design projects tend to stop after screening, characterizing, or optimizing. However, once a process is optimized, it may need to be implemented in manufacturing. To make the process manufacturable, the process noise variables (e.g. raw material batches, various machines, various operators, etc.) need to be considered. Robust design provides a method to leverage controllable factors to mitigate the transmission of variation from noise variables to process outputs. A dual response model is considered to keep the process mean on target, while reducing noise as much as possible.
In addition, before release of a process to manufacturing, the effects of noise can be quantified via a ruggedness test to ensure that noise variables are not drivers of the process. Both robustness and ruggedness are practical methods to help to make processes more manufacturable.
