Prototype Model

> A prototype is a working model that is functionally equivalent to a component of the product.

> In many instances the client only has a general view of what is expected from the software product.

> In such a scenario where there is an absence of detailed information regarding the input to the system, the processing needs and the output requirements, the prototyping model may be employed.

> This model reflects an attempt to increase the flexibility of the development process by allowing the client to interact and experiment with a working representation of the product.

> The developmental process only continues once the client is satisfied with the functioning of the prototype.

> At that stage the developer determines the specifications of the client’s real needs.
