The basis for effective scitech communications is formed by: focusing on the needs of the audience; structuring the substantive and language content accordingly; concentrating on accuracy, clarity and brevity; meeting logical requirements; and presenting in a communicative style and layout, including the use of visuals. In many scitech communications, the Appendix is the right place for detail not of immediate interest to most readers; this option is grossly under-utilized.

The detection of flaws in a list provides an opportunity to widen the perspective on the list content [1]. An additional opportunity occurs when the list heading has two distinct meanings. The list may then be represented better by a two-dimensional array. The case considered is that of the term function used in a list heading. Split into its most common meanings, objective and means used, it provides a new view on the list content. It produced, for instance, a two-dimensional structure for the main functions of language.

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.
