Chapter 24: Design Patterns :

Problem: Allow the client the choice of many alternatives, but each is complex, and you don't want to include code for all.

Solution: Make many implementations of the same interface, and allow the client to select one and give it back to you.

Gives the designer flexibility, keeps the code size down.
