:? There are how many types of use case diagrams? 1 overview use case diagram and many expanded(detailed0 use case diagrams. I have problems in breaking down into how many levels? I need help in this?
Tan,
See it as grouping. For example you will have a high level diagram that consist of a subject boundary and approx 5 packages.
The packages are the subject bounaries of your next diagram etc etc.
I generally use as rule not more than 5 use cases or packages in a subject boundary.
So how many levels? Well that is up to you, it depends what business process you describe aslong levels do not dictate sequence (solution) you be ok.
thank you
