An application state change. Application functions and other application behavior may be triggered or interrupted by an application event. Also, application behavior may raise
events that trigger other application behavior. Unlike processes, functions, and interactions, an event is instantaneous; it does not have duration. Events may originate from the environment of the organization (e.g., from an external application), but also internal events may occur generated by, for example, other applications within the organization. The name of an application event should preferably be a verb in the perfect tense; e.g., “claim received”
