Advice for Writing Sentences

  • Delete words whose absence doesn’t significantly deter from the meaning of the sentence.
  • Keep your sentences short.
  • Be consistent regarding the Oxford comma.
  • Avoid passive voice, which often leads to ambiguity and confusion.
  • When feeling the need to use a semicolon, parenthesis or an em dash, consider breaking the thought into separate sentences.
  • Maintain structural and stylistic parallelism across your headings and list elements.
  • Know the difference between such as and like and use them accordingly.

Advice for Writing Paragraphs

  • Place your most important point in the beginning of the paragraph.
  • Split long paragraphs into several short ones for easier reading and skimming.
  • Avoid one-sentence paragraphs unless you want to place spotlight on the paragraph.

  • Make sure the sentences in the paragraph support the paragraph’s objective.

Tips for Email Messages

  • Lead with the strongest statement to grab attention.
  • Assume the recipient will read only the first 2 sentences.
  • Use the Subject line to get your main point across.
  • Keep the message personally-relevant to the reader.
  • Don’t respond in the heat of the moment. Take time to reflect.
  • Be specific about what action you’d like the reader to take or which conclusion the reader should reach.
  • Consider whether email is the best medium for your message.

Tips for Longer Reports

  • Use a consistent, generally-accepted style for capitalizing words in a title.
  • Pick a title that’ll catch the reader’s attention while also setting their expectations.
  • Create a strong executive summary that stands on its own even if the reader ignores the rest of the report.
  • Split the report into multiple sections to logically group and separate contents.
  • Strive for a simple structure, avoiding deep nesting of headings and lists.
  • Include at least one paragraph between two headings for an introduction or transition.
  • Use the word processor’s style management features for consistent formatting of headings and other text.
  • Craft captions that guide readers to the conclusions you want them to reach about the chart or figure.
  • Place lengthy technical excerpts such as large code fragments into an appendix.
  • Refer to every figure and appendix section from your main text.
  • Make sure the headers and footers include the right notices (copyright, confidential, page number, etc.).

Formatting Guidelines

  • Err on the side of simplicity when selecting a visual style for your document or message.
  • Use italics or boldface, not both, when emphasizing.
  • Know the difference between em dashes and hyphens, and use them accordingly.
  • Avoid breaking short lists or paragraphs across pages.
