Inheritance of Use-Case-Actor-Association in include/extends Sub-Use-Cases

Hi all,

I have created the following Use-Case-diagram:

What I want to express is, that the actor “Verantwortlicher” is communicating with “Fall ausführen”, but also with the included sub-cases like “Fallaufgabe bearbeiten”. The actor Mitarbeiter, however, should only communicate with the case “Fallaufgabe bearbeiten”.

Is this the correct modelling to express that information? Or do I need a assoziation from each inculded sub-case to the actor “Verantwortlicher”?

Best regards

What you have drawn makes sense to me and models what you described.
