The basic idea in Prototype model is that instead of freezing the requirements before a design or coding can proceed, a throwaway prototype is built advantages and disadvantages of on the job training pdf understand the requirements. This prototype is developed based on the currently known requirements.
Prototype model is a software development model. Prototyping is an attractive idea for complicated and large systems for which there is no manual process or existing system to help determining the requirements. The prototype are usually not complete systems and many of the details are not built in the prototype. The goal is to provide a system with overall functionality.
Since in this methodology a working model of the system is provided, the users get a better understanding of the system being developed. Errors can be detected much earlier.

They are excellent for designing good human computer interface systems. Whos the creator or author of this particular prototype model?
Changes in the program are simple and intuitive.
