Organisation is the internal structure of a piece of writing, the thread of central meaning, the pattern and sequence, so long as it fits the central idea. Organisational structure can be based on comparison-contrast, deductive logic, point-by-point analysis, development of a central theme, chronological history of an event, or any of a dozen other identifiable patterns. When the organisation is strong, the piece begins meaningfully and creates in the writer a sense of anticipation that is, ultimately, systematically fulfilled. Events proceed logically; information is given to the reader in the right doses at the right times so that the reader never loses interest. Connections are strong, which is another way of saying that bridges from one idea to the next hold up. The piece closes with a sense of resolution, tying up loose ends, bringing things to a satisfying closure, answering important questions while still leaving the reader something to think about.
