Three decades ago I had a colleague in Mechanical Engineering named Jack Matson. Jack taught a class popularly known as Failure 101. It was a required introductory course, and the core assignment for each small group of students was to (a) create some “thing,” for example, a mechanical gizmo, (b) run it until it failed, and (c) write up a full analysis of the failure. Students whose thing did not fail received Fs—the group that made and marketed fudge never succeeded at failing, so they got Fs.
