Question

Draw a statechart diagram based on the following hints: - In a purchasing system, when an order is placed the order starts in the Initialized state. - When the order is processed, the state changes to Processing. - An order that is Processing can become ReadyForPackaging when the order is fully prepared. - The order that is ReadyForPackaging can change back to Processing in case the customer updated the order or can become Packaging if no updates are requested. - Finally the order would become Packaged, which indicates that no more changes to its state are possible. Note: Use your judgement for how to represent the initial state, final state, and the five states mentioned above and provide clear representation of the transitions (a minimum of 5) between the states along with the events and actions. Also make sure to use guards (at least once) when necessary.
