What somebody or something does
Introduction to the notion
This notion is elementary, meaning that it is a core notion and that methodology contributes in no way to its definition. It is a starting point everyone can understand without debate.
This definition is inspired by the one from the Oxford dictionary but it has been enlarged. Both by choice and for practical reasons, the definition covers both human and non-human beings. In doing so, it enables us to attribute action to things and systems, such as organizations or any type of artificial system. Indeed, more and more often, an action can be reassigned from a human being or a human organization to an artificial solution.
Method recommendations: An action should always be named by a verb.
