Various versions of User Interfaces are tested to see how clients respond. Client response is important for main dialogs, such as a sign-up screen for a website or an e-commerce application. Working with User Interface prototypes instead of "real" User Interfaces enables you to work with small details (such as color or the position of a button), as well as a substantially reduced designer and programmer overhead in the design phase. By building mock-ups or prototypes, you receive fast feedback from prospective users for future designs. User Interface prototyping makes this possible. The feedback loop makes for quicker sophisticated designs that work for everybody, which is what matters.

You can build mock-ups or prototypes to meet the following objectives:
