Main Description



The user-interface designer role is not responsible for implementing the user interface. Instead, this role focuses on the design and the "visual shaping" of the user interface, by: capturing requirements on the user interface, including usability requirements building user-interface prototypes involving other stakeholders of the user interface, such as users, in usability reviews and use testing sessions reviewing and providing the appropriate feedback on the final implementation of the user interface, as created by other developers; that is, designers and implementers.

Staffing



Skills The User-Interface Designer may come from a creative and visual arts background instead of a business, engineering or computer science background. The User-Interface Designer focuses on the usability of the system.


Assignment Approaches Especially in larger projects, a separate group of people is often formed in which everyone plays the user-interface designer role. This group focuses primarily on the user interface and the usability aspects of the system. This is important because of the following: the skills required by a user-interface designer often need to be improved and optimized for the current project and application type, with potentially unique usability requirements, and this requires both time and focus the risk of "mixed allegiances" must be delimited; that is, the user-interface designer needs to be influenced more by usability considerations than implementation considerations
