1. how to show alternatives (if.. else)?
2. how to indicate sending to another use case?
I would appreciate our suggestion. Thanks.
1. I have seen many ranchers mentioned Cade's book is very helpful. So which Cade's book are you talking about?
2. I'm curious that you have 6 sequence diagrams. Did you provide one sequence diagram to each of the use case mentioned in its use case diagram, one sequence diagram to each of the use case provided with detailed info in the requirement?
