System Example: Dishwasher Three components to control: a tank, a jet, a heater The dishwasher washes dishes by spraying the water stored in the tank using the jet The jet sprays the water to rinse the dishes and sends pulses of water to wash them After dishes are clean, the heater activates to dry them Dishwasher’s cycle: washing, rinsing, drying Cycle mode: Quick, Normal, Intense Dishwasher can be stated only if the door is closed

Use Case Diagram A Use Case Diagram shows typical interactions between the system Under design and external actors who may want to interact with it. Actors Packages Use Case Generalization Arrows Association Lines Stereotypes <<Uses>> <<Extends>> <<Inheritance>> System boundary
