ABSTRACT
The objective of this book is to provide a theoretical foundation and operational tools to effectively prepare the content that needs to be presented so that a user is able to make correct decisions regarding the purchase of goods and services and be able to obtain information about items of interest. Content preparation is an integral part of usability. It answers the question what information needs to be presented for effective decision making. Once content preparation has been established, the question “how to present what” can be answered. If too much information is provided, then two problems may occur: (1) it may take too long to make decisions, and/or (2) it may increase the probability of making a wrong decision. On the other hand, if not enough information is available to the decision-maker, inappropriate suboptimal or incorrect decisions may be made. Content preparation as presented in this book will provide guidelines as to what information is needed for decision making by American and Chinese populations.
