Abstract
The problems in technical communications are related more to logical structure than to language. Structure problems occur at document, section, paragraph, and sentence levels. Editing is most effective if it deals with structure first. Structure deficiencies can be detected by applying a range of logical analysis criteria to each text part: looking at the nature and quality of its content and the use of the appropriate discourse sequence. The nature of the content determines where the text part belongs in the section or elsewhere in the document structure. Sufficient definition eliminates vagueness. The correct discourse sequence determines the internal structure of the text part. Lists, headings, classifications, and organograms must comply with the laws of categorization and relevant logical criteria, including some arrived at by lateral thinking.
