Prototyping can be used during requirements determination to collect user requirements and present them in the form of a working system prototype. 1) Users can look at, play with, and compare the prototype to their system requirements. 2) Analysts can then adjust the prototype to better fit what the users have in mind. Throwaway Prototyping: Throwaway prototypes are developed from the initial requirements but they have not been used for the final product and are not an alternative to the written specification of the requirements. It enables quick prototyping and commits to throwing the prototype away. If the users can get quick feedback on their requirements, they may be able to refine the requirements early in the development of the software. Then changes can be done early in the development life cycle. The throwaway prototype has a short project timeline and easier and faster to develop the interface. This type of prototyping can be used at any time in a project by any of the project’s personnel. Throwaway prototypes actually do nothing, it’s just presentations only for a limited purpose. Soon it will be starting to become a thing of the past. This type of prototyping is not getting used as much now. Evolutionary Prototyping: Evolutionary Prototyping is considered to be the most fundamental form of prototyping and this prototyping type is also known as breadboard prototyping. The main concept of this prototyping type is to build a robust prototype and constantly improve it. These prototypes are built only with well-understood requirements instead of acknowledging all the requirements. It allows developers to add features or make changes that couldn’t be devised during the requirements analysis and design. Developers are helped to develop the part by part of the system considering the usability aspects and this type of prototype is delivered as a working system to the end user.
