Take Away: An actor is a person or system that fills a role and interacts with another system. An actor supplies a stimulus to the system. When establishing actors of your system, do not think in terms of a specific person, think in terms of their role. Do not name an actor the name of the person filling the role. If Bob is our Sales Clerk, name your actor Sales Clerk (not Bob).

Actor (UML) - An actor is a person or system that fills a role and interacts with another system. An actor supplies a stimulus to the system. When establishing actors of your system, do not think in terms of a specific person, think in terms of their role. Do not name an actor the name of the person filling the role. If Bob is our Sales Clerk, name your actor Sales Clerk (not Bob).

An actor is a person or system that fills a role and interacts with another system (a point of interaction).

When establishing actors of your system, do not think in terms of a specific person, think in terms of their role. A single person in the real world can be represented by several actors if they have several different roles in relation to a system.
