When and why should I use UML

Question

I'm a beginner in this subject. For my point UML is very useful for planning projects. But should I use even in small projects? If so, this would be effective for productivity? Or would take some time, that the benefits would be shown only in great projects?

Answer 1

UML is as you stated in your question, a tool for project planning. I my experience, UML is only used for medium to big projects, where things quickly could get messy and unstructured. Personally, I wouldn't use UML on smaller projects, since it's pretty time consuming and doesn't really help out regarding structure since you probably already know everything about the project beforehand. It really depends on how structured you need to feel and what you have to do to feel like you have control. For smaller projects, i generally use WireFrames to plan the GUI. Good luck!
