Non-functional requirements in use case diagrams
« on: November 26, 2008, 01:09:34 am »
Hi, I would like to know whether its possible to model non-functional requirements in use case diagrams, or use some other UML diagram for this purpose. Reason is we have a non-functional requirement for a SOA service to be called, and a specific client system requires that the SOA call go via system A, while our service is exposed in system B. One could model this as a use case, though I understand use cases are there for functional requirement modelling. Thanks for the help.

Stereotypes will help you here.
If you model a UC you can give it the stereotype NFR and with some discipline it will lead you where you want it.
You can also associate a constraint of type NFR to the UC if it is a NFR related to the UC only.
