Explain the Throw away prototype
In this technique, prototype is discarded once its purpose is fulfilled and final system is built from scratch. Prototype is built quickly to allow the user to rapidly interact with a working system. As prototype has to be eventually discarded, attention on its speed, maintainability, implementation aspects and fault tolerance isn't paid. In requirements defining phase, a less refined set of requirements are quickly defined and throw away prototype is constructed to determine feasibility of requirement, validate utility of function, uncover missing requirements and establish utility of user interface. Duration of prototype building must be as less as possible since its advantage exists only if results from its use are available in timely fashion.
