LSSGB: When selecting and scaling the process input variables for a DOE , which of the following is NOT a desirable approach?
OPTIONS
- Include as many important factors as possible
- Set factor levels at practical or possible levels
- Combine process measurement responses when possible
- Be bold, but not foolish, in selecting high and low factor levels
ANSWER
Combine process measurement responses when possible
EXPLANATION
Note that a negative response is requested. Answer choice c is not a good idea. If two or more measurement responses are combined, then the important factor (between them) may remain hidden. The other options (a, b, and d) are valid, prudent actions.
