An executive summary previews the main points of a longer report in a concise manner for readers without time to read the full report. It should provide an overview of the key points and conclusions in the report. To write an effective executive summary, one should be familiar with the entire report and capture the main recommendation or purpose in one to two sentences. The summary should then provide a short paragraph on each major point in the same order as the full report and close with a brief reiteration of the main idea. The creation process involves listing main points, writing simple sentences on each, and adding explanatory details while avoiding unnecessary technical language.
