Give your essay a title that tells what and why you are writing.  For example:  The CDC’s Decision to use a Zombie Apocalypse to Increase Emergency Preparedness in the United States: An Evaluation of Pre-campaign Measurement Strategies.  The words “The CDC’s Decision to Use a Zombie Apocalypse to Increase Emergency Preparedness in the United States” tell your reader why you are writing; the words “An Evaluation of Pre-campaign Measurement Strategies” tell the reader what you are writing.
Use the introductory section of your essay to give background or overview of the topic the paper will present.  The introduction must have a clear, well-developed thesis statement that ensures the reader knows exactly what the paper will discuss and the order in which information will be presented.
Use the body/discussion paragraphs of the essay to present the evaluation of the data you gathered from the case study.  Ensure each body paragraph has a topic sentence that connects to the thesis statement of the essay, fully details one angle of your overall discussion, and offers a summary sentence that brings the paragraph to a satisfactory close and allows for smooth transition to the next paragraph.
Use the conclusion of the essay to summarize the essay’s main points.
