In my estimation, if you really want to gain an understanding of designs running what-if analysis I would choose one of the smaller designs say a full factorial 3 variable design, look at the +,- settings for various factors, set response levels to match these patterns, and run the analysis to see the impact of these ordered changes in response. Below is the Minitab output which treats both batch and treatment the same and tests the hypothesis of no effect. One of my pet peeves is when people say that a point outside the control limits is a special cause. Utilise options available on Minitab to customise designs.
