Summary
If your memo is longer than a page, you may want to include a separate summary segment. However, this section not necessary for short memos and should not take up a significant amount of space. This segment provides a brief statement of the key recommendations you have reached. These will help your reader understand the key points of the memo immediately. This segment may also include references to methods and sources you have used in your research.
Discussion
The discussion segments are the longest portions of the memo, and are the parts in which you include all the details that support your ideas. Begin with the information that is most important. This may mean that you will start with key findings or recommendations. Start with your most general information and move to your specific or supporting facts. (Be sure to use the same format when including details: strongest to weakest.) The discussion segments include the supporting ideas, facts, and research that back up your argument in the memo. Include strong points and evidence to persuade the reader to follow your recommended actions. If this section is inadequate, the memo will not be as effective as it could be.
