Ask HN: Is UML still relevant today? 12 years ago
Like a few have pointed out, it depends, but even then not the whole beast. Certain few diagrams are useful in the early stage, where having diagrams is fastter to communicate ideas and concepts across. Other than that UML is a wastage of time as the software base evolves - it cannot pace itself well to that dyanamism and agility; it has no inbuilt dialectical characteristics. However, document core stable parts could be done. I personally do not know any body who does though.
