* How can a class (the same construction process) create different representations of a complex object?
* How can a class that includes creating a complex object be simplified?

Creating and assembling the parts of a complex object directly within a class is inflexible.  It commits the class to creating a particular representation of the complex object and makes it impossible to change the representation later independently from (without having to change) the class.

The builder design pattern describes how to solve such problems:
* Encapsulate creating and assembling the parts of a complex object in a separate  <code>Builder</code> object.
* A class delegates object creation to a <code>Builder</code> object instead of creating the objects directly.

A class (the same construction process) can delegate to different <code>Builder</code> objects to create different representations of a complex object.
