what is the purpose of an introduction in a report
Introduction (writing) Keeping the concept of the introduction the same, different documents have different styles to introduce the written text. For example, the introduction of a Functional Specification consists of information that the whole document is yet to explain. If a Userguide is written, the introduction is about the product. In a report, the introduction gives a summary about the report contents.
Dramatic structure In the rising action, a series of events build toward the point of greatest interest. The rising action of a story is the series of events that begin immediately after the exposition (introduction) of the story and builds up to the climax. These events are generally the most important parts of the story since the entire plot depends on them to set up the climax and ultimately the satisfactory resolution of the story itself.[14]
