This text helps the reader generate clear, effective documentation that is tailored to the information requirements of the end-user. Written for technical writers and their managers, quality assurance experts, and software engineers, the book describes a user-centered information design method (UCID) that should help ensure documentation conveys significant information for the user. The UCID shows how to: integrate the four major information components of a software system - user interface labels, messages, online and printed documentation; make sure these elements work together to improve usability; deploy iterative design and prototyping procedures that minimize flaws and save time and money; and guide technical writers effectively.
