The purpose of the executive summary is to enable the reader to get an overview of the main contents of the report without having to read the whole document. The summary should be no more than a page (about 300 words) in length and briefly cover:
In your introduction, you should set your research in context and indicate its aims, or the research problem it intended to address.
You might include:
Background or events leading up to the request for the report and important contextual information e.g. information on the organization and its management structure (again, this can be written as a separate section if it is necessary to include quite a lot of background detail).
The body of your report will vary depending on the audience and purpose. The variety of reports, such as the progress report, the justification report, the feasibility report, the proposal report, etc., all have different content in the body.
The final portion of your report is the place where you draw all the threads together, the points arising from the findings section, and further discussing the most interesting or unexpected findings and trying to account for these. There should be no new data introduced in this section – conclusions are a drawing together of the information already presented.
