Chapter 1. The Deep Changes > Changing the Process for Interface Design

Changing the Process for Interface Design

Many companies expect developers to sit down and just draft the interface design without doing expert reviews, data gathering, or any testing. If your organization currently uses this approach, you must be willing to learn and use a different approach. User interface design must be an iterative process. You sketch and prototype an interface, then change it, then get feedback from users, then change it, again and again. There are two reasons why effective interface design must be iterative.

  1. Design is a process of deciding among many sets of alternatives. Getting them all correct the first time is virtually impossible.

  2. As users see what an interface is actually like, they change their conceptions and expectations—thus the requirements change.
