Primary Scenarios and Use cases

Question

Should you write a primary scenario for every use case in a use case diagram separately or write one primary scenario that incorporates all the use cases in the diagram?

Answer 1

I'm not sure what your definitions are, but I'm pretty sure the convention is this:

• Use case diagram - a diagram associating actors to use cases.
• Use case - a set of actions, including variants (ie, the primary and alternative paths).
• Scenario - a specific sequence of action (ie, a single path - primary or not).

So by these definitions, you should write a (primary) scenario for each use case.
