RE: (ROSE) Question About Actors

[Colin Gourlay]

Well I am fairly new to the UML world so the following may not be 100% accurate!

 

My understanding of an Actor is that it is something or someone that either gives value to or gets value from say a use case in which it is associated.

 

The actor may be a primary actor in that it initiates actions within the system under discussion or it may be a stakeholder (whereby it has a vested interested in the value of a given use case).

 

IMHO an actor need not necessarily be an entity outside the scope of the system - they may in fact be part of it. 

 

Hope this helps

 

Regards

 

Colin

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
