| Summary | Provide an interface for creating families of related objects without specifying their concrete classes. | Construct a complex object step by step so the same construction process can create different representations. | — |
| Intent | Provide an interface for creating families of related objects without specifying their concrete classes. | Separate the construction of a complex object from its final representation. | Allow an object to alter its behavior when its internal state changes by delegating state-specific behavior to separate state objects. |
| Decision factors | |||
| Problem | Client code needs to create families of related objects, but hardcoding concrete classes makes the code rigid and hard to swap. | Constructing complex objects directly can make required steps, optional values, and validation hard to manage. | An object behaves differently depending on its internal state, and conditional logic is becoming hard to manage. |

| Integration notes | Abstract Factory is especially useful when your app must produce matching sets of related objects for a theme, provider, platform, or pipeline. | Builder is most useful when construction must happen in controlled steps and the final object has many optional or ordered parts. | State is useful for workflows, media players, order lifecycles, and any domain where behavior changes as the object moves through a lifecycle. |
