When will I ever need to use Venn Diagrams?

This is a fun one. I have liked the idea of using Venns for work, but for technical people, they are typically too high-level (i.e. they summarize something obvious).

So my oldest came home and had me review his homework of Venns. Since "I'll never use this" has become a disappointing game for him, he asked if I used these today. I thought about it and said, "No". But I did mention that I have used them in the past.  He left happy.

The next morning before he went to school I had an early morning meeting, and ended up needing to review a document of product failure precipitation techniques (processes to simulate aging effects and find poor design or manufacturing errors). 

At the top there was a Venn diagram that not nearly as complicated as this one (but more proprietary):


sad face
That was not a happy morning for my son, since he's trying negotiate his way out of fancy math by saying he'll never use this stuff.
