The prototype is an important draft design that precedes the development of the original design layout. It is intended not only to show the structure of the future site, but also the site map, the interrelation of its main pages. Prototyping is a process designed to significantly reduce the time to develop a site, due to the focus of the designer on the main functional and marketing factors:

• The prototype gives the customer a complete idea of how the site will look like in the final result;
• Prototyping allows you to streamline the design development process, focusing on important interface elements;
• A site’s sketch is an irreplaceable thing if the client still does not fully understand what he expects from the site, what functions each page will carry. Careful planning at the prototyping stage makes it possible to avoid global changes in the finished layout;
• At the prototyping stage, it is possible to identify unnecessary elements that are best abandoned;
• This process significantly reduces the workload of the designer in developing the project, and thus saves the customer’s money;
• Having a prototype in hand, the designer and customer more clearly represent the final result;
• Prototype development involves the involvement of the customer, contributes to more productive work, process consistency.

Having a prototype makes it easier to understand the tasks for each team member. It gives them the opportunity to do more realistic planning of development deadlines and more accurately determine the cost of work. Website development in strict accordance with the prototype allows not taking into account the cost of changes and modifications.
