Procedure, Process, Concept, Structure, Classification, Principle, Fact
Information blocks replaced paragraphs as the fundamental unit of meaning and presentation. Unstructured information was “clustered” into information blocks with clear labels, which were linked together and further refined in the writing process. Horn and his collaborators identified 40 types of information blocks that could be categorized as one of seven types: Procedure Process Concept Structure Classification Principle Fact. These types were standardized across all kinds of topics and projects. Research by Horn and others indicated that about 80% of virtually any subject matter could be classified using this system. It was found that by chunking a body of information in this way early on in a project, there were tremendous benefits at every subsequent stage.
