A prototype is an early sample, model, or release of a product built to test a concept or process. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. A prototype can also mean a typical example of something such as in the use of the derivation ' prototypical '. Prototypes explore different aspects of an intended design: . In general, the creation of prototypes will differ from creation of the final product in some fundamental ways:.
What is prototyping?
Rapid prototyping RP is the production of a physical model from a computer model without the need for any jig or fixture or numerically controlled NC programming. This technology has also been referred to as layer manufacturing, material deposit manufacturing, material addition manufacturing, solid freeform manufacturing and three-dimensional printing. In the last decade, a number of RP techniques has been developed. These techniques use different approaches or materials in producing prototypes and they give varying shrinkage, surface finish and accuracy. Virtual prototyping VP is the analysis and simulation carried out on a fully developed computer model, therefore performing the same tests as those on the physical prototypes. It is also sometimes referred to as computer-aided engineering CAE or engineering analysis simulation. This paper describes a comparative study of the two prototyping technologies with respect to their relevance in product design and manufacture.
Explains and defines prototyping in terms of its character, actors and types. Examines four aspects: its use in the software development process, its goals, horizontal and vertical and the relationship between prototype and application system. Clarifies the distinction between breadboard and prototype. Budde, R. Report bugs here. Please share your general feedback.
Creating prototypes is more than just the delivery of more solid presentations; it is an highly practical manufacturing strategy. Prototypes provide the best testing models because they are a physical manifestation of the product and can be tested to find any characteristics that could make or break the design. Manufacturers can then take the information gathered from the prototype and make changes to the actual product. There are key differences between prototypes and actual products. Such differences usually appear in three fundamental ways:. A good prototyping company will save a manufacturing company time, manpower, and money — and can deliver and be trusted with an original design.
DIFFERENTIATE BETWEEN MODEL AND PROTOTYPE
Prototyping is defined as the process of developing a working replication of a product or system that has to be engineered. It offers a small scale facsimile of the end product and is used for obtaining customer feedback as described below:. This model is used when the customers do not know the exact project requirements beforehand. In this model, a prototype of the end product is first developed, tested and refined as per customer feedback repeatedly till a final acceptable prototype is achieved which forms the basis for developing the final product. In this process model, the system is partially implemented before or during the analysis phase thereby giving the customers an opportunity to see the product early in the life cycle. The process starts by interviewing the customers and developing the incomplete high-level paper model. This document is used to build the initial prototype supporting only the basic functionality as desired by the customer.

The terms prototype and model describe tools frequently used in product design and development processes. There is a certain amount of confusion because the terms are sometimes used interchangeably. In general, however, a prototype is a working representation used to detect flaws or problems in advance of production. A model is a non-working representation used to illustrate the product, and may be constructed at any stage in the product cycle.
