Revising is the process of ensuring a document accurately conveys the intended message in a professional manner. When revising alone, one should read and reread the document, check the overall meaning and clarity, organization and logical flow, and correctness. Effective self-revision techniques include letting the document sit overnight, reading it aloud to identify issues, using a checklist of common problems, and reviewing a printed copy to see it as readers would. Revision software can help with spelling, grammar, and finding synonyms, but cannot replace careful human review, as software does not understand context like the topic, audience, and purpose.
