Why is UML necessary in Object Oriented design?

Is UML useful Reddit?
Most useful at the systems engineering scope. These would be more formal, usually in an established, fully featured tool, but not always. UML diagrams are less useful at the software design scope but still helpful for communicating a design. The most effective ones are class (obv), activity and sequence.Feb 16, 2021

UML isn't bidirectional. ... UML can't capture many of the high-level details necessary to build software. For example, there's no way to represent Properties, or Static members. You end up looking at the code anyway because the UML is so imprecise-- even at the highest architectural level.May 1, 2005
