A structured, or single-source, approach to technical communication can be contrasted with the traditional, unstructured or 'page orientated,' approach. In this approach, technical communications are created as whole pieces of content, often specific to a particular product line or configuration. By contrast, in a structured approach content is authored by topic in distinct sections that can be mixed and matched according to defined elements within 'chunks' of content.
