A prototype is a sequential structure with a schematic representation of the main semantic blocks and functional elements. This is a tool that helps avoid a large number of edits, agree on everything upfront, and significantly save time on project development.

Prototypes can vary in the level of visual detail and the number of interactive elements. It can be a simple sketch on paper or a detailed clickable structure of many pages. When prototyping, our main task is to work out the following:

• The sequence and architecture of blocks on the page;
• Functionality and connections between elements;
• Copywriting and placement of semantic accents.

Thanks to the prototype, we get:

• Clarification of requirements. It allows you to accurately define the requirements for the product and avoid edits at the design and development stages. Seeing the prototype, all project participants understand what the final product should be and what it includes.

• Saving time and money. Skipping the prototyping stage and starting with design right away, you can drown in alterations, make a bunch of edits from the customer in the spirit of «everything is wrong, I imagined it differently» and get a project that will go into the red.

• The first feedback on the product. The prototype can be used to test ideas and collect feedback from users, the team, and the customer. This allows you to find weaknesses and improve the product before starting its full development.
