Hi

Do I need to create one sequence diagram for a successful flow and a second sequence diagram for a failure flow (alternative flow if an exception occurs)?
per example, communication with an external system


Kind regards

Yes. Major flows should have separate sequence diagrams.

Hi,

I didn't create alternative sequence diagrams for failure scenaros.
I did where possible create one sequence diagram per use case. In some cases though, the use case was long and inluded 2 different logical scenarios (i.e. Buy at current price / Buy at set price) In those case I had 2 sequence diagrams.

I hope this helps.

If you long sequence diagram has alt flows, that's ok too.
