What characteristic of a report requires it to be free from unnecessary details?

The requirement for a report to be free from unnecessary details is best described by the characteristic of conciseness. Conciseness involves delivering information in a way that is brief yet comprehensive, focusing on essential points without adding superfluous content that could distract or confuse the reader. Upkeeping conciseness enhances the effectiveness of communication by ensuring that the primary message is conveyed clearly and efficiently. This characteristic is especially important in reports, where the goal is often to present factual information in a manner that is easy to digest and understand, allowing readers to quickly grasp the core aspects without getting bogged down in extraneous details.

In contrast, clarity focuses on the intelligibility of the information presented, correctness pertains to the accuracy of the content, and completeness ensures that all necessary information is included. While these aspects are also important in report writing, they do not specifically emphasize the elimination of unnecessary detail as clearly as conciseness does.
