• Creating objects inside a class with a factory method is always more flexible than creating an object directly
• Gives subclasses a hook for providing an extended version of an object
Connects parallel class hierarchies
• In the examples we've considered so far, the factory method is only called by Creators. But this doesn't have to be the case;
clients can find factory methods useful, especially in the case of parallel class hierarchies";
