Rarely, also 25 and 26 full factorial designs were applied for optimization purposes in the literature.

The minimal k value should be 2 to enable a distinction between the factor levels, and often k = 5 is used as default value. The lower the k value for a factor, the smaller the examined interval, and the stricter that factor is to be controlled during later use, because only robustness in the narrow interval is verified. On the other hand, a higher k value increases the probability that a significant effect occurs in the examined interval, but allows a less strict control of the factor if no important effect is observed.

For the screening phase, the following steps can be distinguished: (1) selection of the factors to be evaluated and their levels; (2) selection of the screening design; (3) definition of the responses; (4) planning and execution of the entire experimental setup, and experimental determination of the responses; (5) calculation of the (factor) effects on the responses; (6) graphical and/or statistical interpretation of the estimated effects; and (7) identification of the factors most influencing the method performance.
