What you should present is the synthesis of your work. Show a succinct executive summary of your findings, any recommendations you have, and then as needed, provide any relevant data you’ve collected to support those recommendations. If your recommendation is “We should do X” then it wouldn’t hurt to have a stat readily available reading “45 out of 50 sites observed do X” — or some other explanation as to how you’ve arrived at your recommendation that doesn’t require magical thinking. Also, keep those screenshots ready for any visual learners who prefer an illustrative example.
