1. What is a Plan of Experience (PEX)?

Experimental design is a methodology for visualizing the evolution and level of influence of different possible settings of influential process parameters, which must be determined beforehand by a working group (brainstorming, for example).

At first glance, you might wonder what the point of this approach really is.

However, the major advantage of experimental design lies in the fact that it enables us to optimize the number of experiments to be carried out during the testing phase, by determining in advance the actual factors or combinations of factors influencing the response of the system to be studied.
