If you drew both brushing processes as a UML diagram the variance would be trivial Now compare that variance to the variance options given with machine and computing UX options you’ll see clearly that one (toothbrushing) is less than one stdev different in steps and components for the median use case and one (computing) is nearly infinite variance (no stable stdev) between median use case steps and components. The fa…
Ask any person to go and find a stick and use it to brush their teeth, and then ask if that "experience" was the same as using their toothbrush. Invoking UML is absurd.
