Optionally, you can use the CVALS= option for levels of character type (see "Example of a Full Factorial Design in Two Blocks"). The design is saved in a user-specified output data set (SAVDESGN).

In our coating example, we would call this design a 2-level, 3-factor full factorial DOE. The number of runs would then be calculated as 2^3, or 2x2x2, which equals 8 total runs. There are other ...

Often you do not have the resources for a full factorial design. In this case, a fractional factorial design is a reasonable alternative, provided that the effects of interest can be estimated. Box, ...
