A statechart is a hierarchical state machine, introduced by Harel. Since it is hierarchical, its capability to reduce complexity and state proliferation allows to be used also for real-world problems and not only for toy or theoretical examples. The UML state diagram is an OO adaptation of the Harel statechart.
