The purpose of this cutting-edge collection of essays is threefold: first, it presents the principles of data collection and interpretation or the methodological distinctions of a particular method appropriate to technical communication research. Second, it discusses the foundational principles of the methodologies given the primary discipline in which they were created and applied. Finally, it reflects upon the process of importing and employing these methodologies into the research field of technical communication, and on how technical communication research has contributed to the development and application of these methodologies. Written by many noted scholars in the field and presenting a wide range of research methods, combines theory and practice. Both technical communicators and industry researchers who want to learn more about workplace research and methodologies will find it invaluable, as will beginning and advanced scholars, who will find much that is useful in its variety of subjects.
