User-interface design techniques and human-computer interaction (HCI) evolved from studies of human interaction with machines. The field of human factors was first associated with engineering, as engineers designed machines. However, engineers used precise specifications and predictable behavior and often found the human factor frustrating. Dialogs are used to define a menu hierarchy that allows the user to navigate to each dialog. Each dialog is based on a use case documented early during the inception phase that is classified as requiring a user interface. Discuss the following questions: What are dialog designs? Within an iteration, can analysis and design activities occur simultaneously? Why or why not? How does a developer know when to do analysis and when to do design? The definition of interface design standards states that “general principles and rules must be followed….” Do user interface design standards restrict creativity?
