Event Diagrams

Description:
This task defines the behavior of the system by detailing user-function, and function-function interaction, as well as the function itself. Each event trace details the objects involved, the components they are associated with, the message they send, the messages they receive, the order in which messages are sent and the arguments and return values for the messages.
Risk & Impact:
This task is critical as it defines exactly what will be built. Without a firm specification, the work can not be effectively divided among team members for construction.
