Hi, apologies if this question is dumb.
I’m modelling a system and trying to get my uml up to speed.
I’ve made use cases for all actor interaction with the system, but I’m wondering how I should model critical events in the system and highlight them to anyone reading my design.
As an example… modelling a airplane’s control systems. I’d have use cases for throttle back, applying rudders, pulling back on the stick etc as they are all pilot actions. But if I want to highlight another critical event like, say, running out of fuel or an oil pressure failure that’s not caused by an actor, what should I do please?
Thanks for any help,
tombola…
