How to extend a use case from the Scenario Builder

[Michael Albers]

Thanks all for your answers. I am new to UML and will certainly look into BPMN. That could indeed be the way to go as mentioned by JohnDoe and backed up by Geert and qwerty.

My focus on the technical side doesn't surprise me, since I've been a developer for over 15 years.

Btw, my previous post was posted later than planned. I forgot to submit it and didn't see the posts before it. And, with two answers from EA administrators that contradict, it doesn't get easier for a newbie.  
But it underlines my earlier thought that this is also a matter of opinion.

Anyway, next week Bittner and Spence will arrive on my door mat. I'll look into it further then.
