RE: (ROSE) Question About Actors

[Flum, Michael]

Hi,

  An actor is a coherent set of roles that users of use cases play when interacting with the use cases.

 

  Your definition is okay, but, you last statement bears scrutiny.  A use case can become an actor and it could have been acted upon by another actor.

Hello,

 

My understanding is that an Actor is an entity that is outside the scope of the system under consideration. They help us to define the scope that is outside the system as well as what is inside. Actors act upon the system but are not acted upon.

 

Is this a correct description or is there some thing untrue? Please also add the missing parts

 

Thanks
