When going into a new OOP project, I like to browse the code and create class diagrams for it.

It's intersting to see what classes aren't used at all and where all the associations accumulate.

Also, if the "previous devs" are still around it's easier to talk with them about these pictures, than to talk about 100 text files.




Good point. I find sequence diagrams can be useful in places, as well.
