Prototyping is building a working model quickly that allows the demonstration or study of the salient features of a system, so that sensible decisions about how to build the real system can be taken. It is absolutely not the process of getting a working system cheaply, since a prototype generally has a flimsy underlying architecture, may only have the artifice of processing data without actually being able to do any of the real processing, and may well be rigged so as to work correctly with exactly one set of inputs.
Making changes to a Web site / App once it's finished can be a costly and painful experience. But you can avoid this scenario by first creating and testing a prototype of your site-a scaled-down working model of the finished product. A prototype lets you get a first look at what users will see as they click through your site, and it can expose unforeseen flaws in your structure and navigation. This gives you a chance to fix glitches before they send your site-and your reputation-up in flames.
Prototype is a quick and easy way to test the ideas and assumptions that came together to form your Web site / App. Once you've settled on your method for gathering and organizing information, and after you've turned your site plans into a clickable model, you'll be able to see what will work for your Web site / App and what won't-all without sinking a lot of time and effort into building the final product.
Best of all, prototype results stay private. Users will never know about the problems you corrected during the test-driving process. By the time they get to kick your Web site's / App’s tires, they'll see only a polished, well-constructed machine that handles like a dream and practically drives itself.Prototypes are often useful in studying things like technical feasibility, site structure, navigation and labeling, user-interface design or branding placement.
Prototyping can also be used for proof-of-concept development, where a bare-bones system is built to see if a particular technical approach to a hitherto unsolved problem is practical.
Why Prototype is important?
A Web-site prototype is a bare-bones, clickable model of your site. Although it's just a collection of simple, hyperlinked documents, you can use it to set up and test your site's content organization and ease of navigation.
Building a working model of your Web site / App even though you could spend that time building the actual site / app is worth the effort. Your Web site's / App’s launch is not the time to find out that users get hopelessly lost in a maze of dead-end hyperlinks and confusing paths. By laying down a site's / app’s groundwork early, you save yourself forehead-slapping moments and angry user e-mails later on.
