Want to practice UML? It all starts with writing use cases. This is probably the most important step anyway
No use case template is available yet, since this is still experimental here. However, here’s an example
‘'’What’s the lowest level use case granularity we want?”’
We generally don’t want to write a use case for anything that is not an action that creates value on the system. However, there are situations where use cases will share common sequences of sub actions. It is OK here to create a sub-case in order to avoid text duplication.
