I have set of high-level, abstract business use cases. I want to break down these business cases into more detailed use cases. I would like to indicate in my model somehow that the use cases are a step-wise refinement or decomposition of the business use cases.
I would like to do similar step-wise break downs of other elements like action nodes activity diagrams.
Can anyone tell me how to indicate these refinement/decomposition relationships among my UML elements?
I have been looking and looking on this topic and am lost.
Many thanks in advance.
