When you write your comparison and contrast of different options or alternatives in your executive summary, you should use clear, concise, and consistent language. You should also use transition words and phrases, such as however, on the other hand, in contrast, similarly, or likewise, to show the relationship between the options or alternatives. You should also use evidence, such as facts, figures, examples, or testimonials, to support your claims and arguments. You should avoid using jargon, acronyms, or technical terms that may confuse your audience.
