Actors in Tropos and i* are organisational units, roles, positions or other systems. [Tropos] | The monitoring problem may be characterized from
the point of view of the roles, or Monitoring Actors, involved
into monitoring process [CD-JRA-1.2.2]. One can identify the following
types of actors:
From the adaptation perspective we distinguish between such roles as Adaptation Requestor, Adaptation Designer, Adaptation Initiator, and Adaptation Executor. When certain roles are performed by the Service-Based Applications (SBA) or the environment autonomously, we speak about self-adaptation. Otherwise, the adaptation is referred to as human-in-the-loop adaptation. When the human plays a role of the adaptation executor, we can speak about manual SBA adaptation, performed, e.g., at design-time. [CD-JRA-1.2.2] |
