We want more than just a complete user interface design (which will happen with or without the Usability Engineering Lifecycle); we want a complete user interface design that optimizes user performance and satisfaction, and that is created through a cost-effective development process.
Description
In the Detailed User Interface Design task, we define and (sometimes) document the design based on the Conceptual Model Design and the Screen Design Standards established in previous tasks, so that all pathways, displays, and interactions follow the product user interface standards developed in those earlier tasks. You will recall that aspects of the Conceptual Model Design (see Chapter 8 ) for a typical software GUI include

Decision on whether to design a product- versus process-oriented Conceptual Model
?
Identification of products or processes
?
Rules for the presentation of products or processes
?
Rules to follow for the use of window types
