What is a responsibility?
Let us define Responsibility
The definition of responsibility: a responsibility is the set of tasks, activities, or actions an actor is expected to perform, or allowed to do, according to his or her role.
Example: The responsibility of an Elderly Woman (Actor) as a Shopper (Role) on a webshop (System) is to Register for the Webshop (Task), Add Items to A Cart (Task), and Pay For the Items (Task).
