Describe prototyping

What will be an ideal response?

Prototyping is the creation of a working model for testing and verification of requirements. There are conflicting definitions of prototyping and conflicting opinions on how useful it is. In an object-oriented and component-based approach, prototyping represents an iterative process in which not the whole application, but relatively independent units of it are prototyped and tested. As new units, or subsystems, are developed, the old units are refurbished and retrofitted to fit within the evolving structure.
