ESSAY
19. ANS:
If an event table has not been created, begin by identifying the actors and the functions they perform with the
system. To do so, you must remember two preconditions. First, you must make the system boundary an
automated system so that the actors you identify actually contact the system, that is, have hands. Second, you
must assume perfect technology.

20. ANS:
A system sequence diagram (SSD) is used to define the inputs, outputs, and sequence of interactions between
the user and the system for a use case. A state machine diagram describes the collection of states of each
object.
