This chapter discusses revising business messages to improve clarity, conciseness, and readability. Revising involves improving content, structure, and proofreading for errors. Writers should trim unnecessary words, drop filler phrases, and use active verbs to strengthen messages. Effective document design uses appropriate formatting like white space, font, lists, and headings to enhance comprehension. Proofreading checks for spelling, grammar, punctuation, names, numbers, and formatting consistency.
