Systems are designed to operate according to scenarios, implying that the design of the response of any unit to any event is based on assumptions about the operating scenario. A scenario is a condensed form of the operator's view of the situation
A scenario is a collection of modes representing the designer's perception of the desired system behavior, when operated in its context.
The effective scenario is the set of selections, of all modes.
Formal scenario definition enables detecting situations in which the active modes are out of the design scope.
