- Many architectures start with Factory method, then evolve to AF, Prototype, Builder
- Builder makes complex objects step-by-step. AF makes families of related products. Builder returns the object after all steps are complete. AF returns its object at once.
- AF classes are often made with Factory Method/Prototype
- AF can be used instead of Facade to hide classes
- AF and Bridge can be used together, if you have abstractions which will work only with some real classes.
- AF, Builder, Prototype can be made with Singleton
