Explain two different ways that Global Earth might use prototypes.

Question

What will be an ideal response?

Answer 1

Global Earth might use two prototypingmethods: system prototyping and design prototyping.System prototyping produces a full-featured, working model of the information system. A system prototype that meets all requirements is ready for implementation, so it is especially important to obtain user feedback and assure that the prototype meets all requirements of users and management.
Global Earth also might want to use design prototyping, which is a method for verifying user requirements, after which the prototype is discarded. The approach also is called throwaway prototyping. Design prototyping objectives are more limited, but no less important. The end product of design prototyping is a user-approved model that documents and benchmarks the features of the finished system.
