I would like to clarify whether ARCADIA method allows to create new actors at logical layer, that is, not identified and captured at system layer.
My view is that all logical actors should have been identified and captured at system layer, any new actors identified at logical derived from a deeper analysis should be reflected and updated at system layer.
In addition, whether ARCADIA allows new actors to be defined at logical layer:
Does it mean not all the interfaces will be captured for the System-of-interest (SoI) at system layer?
What is the interface concept when representing an the interface between new actors represented at logical layer and the logical components?
How it is defined the boundary of the System-of-Interest (SoI)?
