In the CONCLUSION to your report, you do a number of important things:

Some research reports end (or begin) with an abstract. An abstract is a highly abbreviated (usually 100-200 words) synopsis of your research. It should describe your rationale and objectives, as well as your methods and findings.

Because of its limited length, an abstract cannot go into detail on any of these topics. Nor can it report on the limitations of your research or offer suggestions for future research. For those, readers will have to read the entire report. But, after reading your abstract, people unfamiliar with your research should know what it is about and whether they want to read the entire report.
