Share on Facebook 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.
Prototypes vs. simulations
It should be similar enough and have sufficient functionality that the designers and engineers building the product can activate it to carry out the functions of the intended product. The simplest definition of model is a representation, usually three-dimensional, that shows the appearance of something. The common uses of the term extend far afield into fashion and arts. In engineering and manufacturing, a model is usually a representation that does not have full functionality and is often constructed at a smaller scale than the intended product.
User Interface and Testing The purpose of a prototype is testing for performance, and the ultimate in prototype testing is done by the end user. The user test pool may be as broadly defined as the entire population of users on a social media platform, for example, or restricted to a specialized group, such as the test pilots who fly experimental aircraft.
As an alternative, rapid prototyping or rapid application development techniques are used for the initial prototypes, which implement part, but not all, of the complete design.

This allows designers and manufacturers to rapidly and inexpensively test the parts of the design that are most likely to have problems, solve those problems, and then build the full design. This counter-intuitive idea—that the quickest way to build something is, first to build something else—is shared by scaffolding and the telescope rule.
Engineering sciences[ edit ] In technology research, a technology demonstrator is a prototype serving as proof-of-concept and demonstration model for a new technology or future product, proving its viability and illustrating conceivable applications. In large development projects, a testbed is a platform and prototype development environment for rigorous experimentation and testing of new technologies, components, scientific theories and computational tools.
An example of such a development can be seen in Boeing Dreamlinerin which the first full sized physical realization is made on the series production line.
Computer modeling is now being extensively used in automotive design, both for form in the styling and aerodynamics of the vehicle and in function—especially for improving vehicle crashworthiness and in weight reduction to improve mileage.

Mechanical and electrical engineering[ edit ] The most common use of the word prototype is a functional, although experimental, version of a non-military machine e. An electronics designer often builds the first prototype from breadboard or stripboard or perfboardtypically using "DIP" packages. Builders of military machines and aviation prefer the terms "experimental" and "service test".
In electronicsprototyping means building an actual circuit to a theoretical design to verify that it works, and to provide a physical platform for debugging it if it does not. The prototype is often constructed using techniques such as wire wrapping or using veroboard or breadboardwith the result being a circuit that is electrically identical to the design but not physically identical to the final product.
Prototyping platforms such as Arduino also simplify the task of programming and interacting with a microcontroller. A technician can quickly build a prototype and make additions and modifications using these techniques, but for volume production it is much faster and usually cheaper to mass-produce custom printed circuit boards than to produce these other kinds of prototype boards.
The proliferation of quick-turn PCB fabrication and assembly companies has enabled the concepts of rapid prototyping to be applied to electronic circuit design. It is now possible, even with the smallest passive components and largest fine-pitch packages, to have boards fabricated, assembled, and even tested in a matter of days.
Software prototyping and Software release cycle In many programming languagesa function prototype is the declaration of a subroutine or function and should not be confused with software prototyping. In prototype-based programming a form of object-oriented programmingnew objects are produced by cloning existing objects, which are called prototypes.
Additionally, the term may refer to the prototype design pattern. Prototype software is often referred to as alpha grade, meaning it is the first version to run. Often only a few functions are implemented, the primary focus of the alpha is to have a functional base code on to which features may be added. Once alpha grade software has most of the required features integrated into it, it becomes beta software for testing of the entire software and to adjust the program to respond correctly during situations unforeseen during development.
After the user evaluation, another prototype will be built based on feedback from users, and again the cycle returns to customer evaluation.

The cycle starts by listening to the user, followed by building or revising a mock-up, and letting the user test the mock-upthen back. There is now a new generation of tools called Application Simulation Software which help quickly simulate application before their development.
Extreme programming uses iterative design to gradually add one feature at a time to the initial prototype. Continuous learning approaches within organizations or businesses may also use the concept of business or process prototypes through software models. This section does not cite any sources. August Learn how and when to remove this template message A data prototype is a form of functional or working prototype.
The justification for its creation is usually a data migrationdata integration or application implementation project and the raw materials used as input are an instance of all the relevant data which exists at the start of the project.
The objectives of data prototyping are to produce: A set of data cleansing and transformation rules which have been seen to produce data which is all fit for purpose. A dataset which is the result of those rules being applied to an instance of the relevant raw source data. To achieve this, a data architect uses a graphical interface to interactively develop and execute transformation and cleansing rules using raw data.
The resultant data is then evaluated and the rules refined. Beyond the obvious visual checking of the data on-screen by the data architect, the usual evaluation and validation approaches are to use Data profiling software and then to insert the resultant data into a test version of the target application and trial its use.
