Evolutionary prototyping

Evolutionary Prototyping (also known as breadboard prototyping) is quite different from Throwaway Prototyping. The main goal when using Evolutionary Prototyping is to build a very robust prototype in a structured manner and constantly refine it. "The reason for this is that the Evolutionary prototype, when built, forms the heart of the new system, and the improvements and further requirements will be built

When developing a system using Evolutionary Prototyping, the system is continually refined and rebuilt.

"…evolutionary prototyping acknowledges that we do not understand all the requirements and builds only those that are well understood."
