So understanding them and being able to create them to enhance your documentation is important . For example these days most documentation is done on Wiki ' s like confluence and most of these have plugins for tools like that makes it easy to add these diagrams to your documentation . Class diagrams aren ' t really used . It ' s IMHO in most cases useless to first write a class diagram and then implement it . It ' s wasteful to go into that level of detail twice . Also in large systems these types of diagrams become completely unreadable . Keep in mind that this kind of documentation is a clear indication that stuff is too complex to just grasp from the code . When you can avoid needed this kind of documentation you should . It ' s better to reduce complexity than to document it .
