Many of our ideas about workplaces have been inherited from 20th-century corporations, in which the elements of the workplace have been packaged in a highly typified configuration: work is done by people belonging to an organization, for some clear reason, at a specific place and time, using specific processes. This configuration is increasingly at odds with work practice, and thus workplace writing researchers must reconsider what is meant by the "workplace." This article argues for treating the workplace as a conceptual decision: a bounded case that researchers construct to enable systematic comparisons. After reviewing how cases are bounded in methodology and practice, the article ends with concrete principles and guidance for bounding such case studies.
