In order to write a summary report, you will first need to gather all of the information that you wish to include. Once you have all of the information, you will need to decide what is the most important information to include. After you have decided on the most important information, you will need to write a brief overview of the information. Be sure to include all of the important details, but do not include any unnecessary information. Once you have written the overview, you will need to write a conclusion. The conclusion should briefly summarize the information that you have presented in the report.
