Weve covered sequence diagrams this week. Sequence diagrams in analysis model the behavior of the system from the users viewpoint. Thus, sequence diagrams are a good whiteboard technique to capture the various usage scenarios described by users. For this weeks Critical Thinking Assignment, create a sequence diagram for an ATM system. Include the following notations: actor, object, timeline, focus of control, message, self-message, return message, asynchronous message, object destruction, steps (in a sequence), and notes.
