The prototype is not used as final product hence may require extra cost.Participation of user and customer feedback is not always possible.

Prototyping Incremental delivering
A prototyping methodology is a software development process which allows developers to create portions of the solution to demonstrate functionality and make needed refinements before developing the final solution.

1.spiral model can be accommodate in prototyping and waterfall model. it is a model of iterative process as prototyping and also a systematic approach to solve a problem as in waterfall model. 2. spiral model take problem as a series of step to solve a problem as in waterfall, and take the contribution of users or customers in each phase as in prototyping model.
the waterfall model gives us prototyping , and spirl model gives us product , so the set of the waterfall accommodat in the spirl to gives us this product.
One advantage of prototyping is the fact that you can make changes to the model before building the actual model. One disadvantage of prototyping is that it can take too long.
Rapid prototyping is a process where a working model or prototype is developed for the purpose of testing the various product features like design, ideas, features, functionality, performance, and output. This process of development of the working model is quite quick. I had taken help of rapid prototyping service of Iannone3D, which is a New Jersey-based Rapid Prototyping and 3D Printing Service Bureau. Thanks.
It is One Of the Prototyping model.
Prototyping model is one of the software development life cycle model. In this we prepare a prototype before the actual product.
prototyping
In prototyping the main principle is that the project is built quickly to demonstrate the customer who can give more inputs and feedbacks . Prototype model is excellent for gathering and refining requirements.
Time is faster as it takes it process and it is easier and safer to see and understand.

Type your answer here... give the limitation of e-r model?how do you overcome this.
