Enaction

-Default Enaction-

A default enaction of a use case description is a stateless enaction process. This means that dependencies amongst description events are assumed to be linear. Thus, events are stepped through from the first to the last. The successive events are availed with a  presumption that the preceding events succeeded. No states for  actors are shown at all even if there are some in the description.

Consider the following description:

To perform a default enaction, simply choose Default option  from the Enact menu. The first enaction window is:

The next one is:

Finally:

This is a stateless process and states are not depicted anywhere. After the last event is invoked and undertaken, enaction finishes.
