A report is an objective presentation of factual information for a specific purpose such as decision making. There are several types of reports categorized by structure, purpose, frequency of issue, subject matter, and persons interested. A formal business report generally contains preliminary parts like a title page and table of contents, a body with introduction, discussion, findings, and recommendations, and supplemental parts like appendices. The principles of a good report are precision, accuracy, relevance, reader orientation, objectivity, clear language, brevity, and clarity.
