Example : State transitions for an order Item received [ not all items checked ] / get next item / get first item Checking [someitems not in stock ] [ All items checked && some items not in stock] do : check item [ All items checked && all items availables ] Dispatching do : initiate delivery Waiting Item received [ all items available] Delivered 107

Transitions to “cancelled” [ not all items checked ] / get next item / get first item Checking do: check item [ All items checked && all items available ] Item received [ some items not in stock ] [ All items checked && some items not in stock ] cancelled Item received [ all items available ] Waiting cancelled Dispatching do: initiate delivery cancelled Cancelled Delivered 108
