Minimalism in structured writing or topic-based authoring is based on the ideas of John Millar Carroll.
Like Robert E. Horn's work on Information Mapping, John Carroll's principles of Minimalism were based in part on cognitive studies and learning research at Harvard and Columbia University, by Jerome Bruner, Jerome Kagan, B.F. Skinner, George A. Miller, and others.
Carroll argued that training materials should be constructed as short task-oriented chunks, not lengthy monolithic user manuals that explain everything in a long narrative fashion.
The historian of technical communication R. John Brockmann points out that task orientation had been enunciated as a principle a decade earlier at IBM by Fred Bethke and others in a report on IBM Publishing Guidelines.
Carroll observed that modern users are often already familiar with much of what is described in the typical long manual. What they need is the information to solve the particular task at hand. They should be encouraged to do them with a minimum of systematic instruction.
Darwin Information Typing Architecture (DITA) is built on Carroll's theories of Minimalism and Horn's theories of Information Mapping.
Minimalism is a large part of JoAnn Hackos' recent workshops and books on information development using structured writing and the DITA XML standard.
