When I was a full time assistant professor of pathogy at Northwestern in 1997-2001, I also picked up an MBA in the university.
There was a business school case study on ice cream. A person would think, what a waste of time - why have a med school professor, interested in health management, work through a case study on ice cream? But I still remember it clearly twenty years later. The ice cream industry is really complicated - keeping it cold but not too cold and in diverse locations and shipping conditions is a big logistical headache. The point of these case studies is you start to realize there is a lot you don't know about everything, and everything is complicated. (FN1)
Thought of this reading an article in today's Wall Street Journal (12/11/2020) on how ice cream manufacturers are restyling their business for the COVID winter we're entering. And, well, there's a lot you don't know and everything is complicated!

I see online that Harvard Business School has two case studies on ice cream, one "Chatanooga," or "Ben and Jerry's." No idea if my class assigned one of those, or a different one.
