      <description>&lt;h2 id=&#34;the-problem&#34;&gt;The Problem&lt;/h2&gt;
&lt;p&gt;Consider the following known industrial problem - we manufacture samples (possibly with different dimensions, characteristics, etc&amp;hellip;)
which we are then testing/verifying. What we want then is to characterize the measurement processes, as it may have multiple sources
of variability. Indeed, the measurement process can depend on the operator and appraisal (i.e. testing machine), the part itself and potentially some other things that we include in our observations.
Additionally to the mentioned single factors, interactions could also be significant
(e.g. some tester or operator is better off with some particular type of the part).&lt;/p&gt;</description>
