In object oriented programming, it is common to delegate some work to other objects. However, if a class delegates the majority of work to another class, it is just a middle man and should be removed. Instead, you should talk directly to the class that implements the behavior rather than going through the middle man.

Conflicts

• Mediator can turn into a middle man that does little other than delegating to other objects.
• Facade by definition delegates to classes in a subsystem that is being hidden from other parts of the system.
