The initial prototype an executable software model is constructed based on either an initial selection of functions or on users needs that have been identified. It is an activity that can occur in software development and is comparable to prototyping as known from other fields, such as mechanical engineering or manufacturing. It also creates a base to produce the final system. Prototype models have one specialty, they can use as a standalone process model or it can be used in combination with other models. A prototype is an early sample of a product that serves as a basis for a future model.

This model allows the users to interact and experiment with a working model of the system known as prototype. Prototype model should be used when the desired system needs to have a lot of interaction with the end users. Spiral model is a riskdriven process model generator for software projects. The incremental build model is a method of software development where the model is designed, implemented and tested incrementally a little more is added each time until the product is. A comparison between five models of software engineering. This prototype model is same as waterfall model, but in this model we need to develop prototype and customer interaction will be there. It helps in saving the later part of issues that might occur. This model is one of the oldest models and is widely used in government projects and in many major companies. It gives the clear picture of software what is being developed and not to the client earlier and before the implementation stage as well. One of the key advantages a prototype modeled software has is the time frame of development. Prototyping is defined as the process of developing a working replication of a product or system that has to be engineered. Typically, online systems, web interfaces have a very high amount of interaction with end. The spiral model supports coping up with risks by providing the scope to build a prototype at every phase of the software development. As the project is openended, no time frame is able to be set.
