Number the Executive Summary with roman numerals, bottom center of the page. Use economy with words. Using short words and sentences challenges writers who deal with scientific or technical information. Readers understand more information. Shorter documents cost less to copyedit, design, print, and distribute.
Shorter documents use less paper.
Write in plain English. Avoid jargon and extra words wherever possible. Locate page numbers bottom center. Full-page illustrations, tables, and graphs should be on numbered pages. Readers look at caption first and, when skimming, may look only at captions.
