Wizards used to install software are a common example of a question-andanswer
interface. The user responds to questions about the installation process,
such as where to install the software or features. Another common example is the
use of the Office Assistant with Microsoft products. When the user needs help,
the Office Assistant asks questions and responds to the answers with additional
questions designed to narrow the scope of the problem. Users unfamiliar with
particular applications or not knowledgeable about a topic may find questionand-
answer interfaces the most comfortable, quickly gaining confidence through
their success.
