The evolutionary prototyping model it training and. Throwaway prototyping is about creating, as fast as possible, a part of the future application to either ensure a feature is technically feasible or to show the feature to stakeholders or potential users in order to gather feedback from them since the source code of this prototype is not reused later when developing the application itself, it makes it a throwaway. Initial, partial version of a software system used to learn about the problem, explore designs and solution techniques.

Evolutionary prototyping is not the same as throwaway prototyping, and making the right choice about whether to develop an evolutionary prototype or a throwaway prototype is one key to success. It is a useful way of exploring ideas, and gaining feedback from user. So i always assume im doing evolutionary prototyping with some parts getting altogether replaced.
However, this is risky since the client sees a system and might equate that with a working system you need to stress that its just a prototype. A prototype model is iterative it seeks to progressively improve the design of a given solution based on customer feedback and input.
