A website or application prototype has several advantages. First, you can view, correct, and customize design details in a test environment. Second, you can also try the interactive elements - application forms, online store functions, as well as complex, moving elements. Third, this enables you to test the design and functionality of the website on different platforms and mobile devices.
If a customer wants to be present at different stages of website development and add new ideas during development, this is a great way to participate in the creation process. The prototype can also be tested and evaluated by a focus group, i.e. potential consumers.
