Clarity in Writing One of the biggest mistakes you can make is related to the clarity of your executive summary.
Always note that your audience [or audiences] are likely seeing your research study for the first time.
This will better prepare you for how to organize and summarize the study.
Remember this is not a brief abstract of 300 words or less but, essentially, a mini-paper of your paper, with a focus on recommendations.
Check to make sure that the summary will make sense as a separate document from the full research study.
By taking some time before re-reading it, you allow yourself to see the summary with fresh, unbiased eyes.
This may only necessitate the rewriting of the introduction and conclusion, but it could require rewriting the entire summary in order to fit the needs of the reader.
If necessary, be sure to consider the types of audiences who may benefit from your study and make adjustments accordingly. "Stay Healthy with a Winning Executive Summary." Technical Communication 41 (1994): 511-517; The Report Abstract and Executive Summary.
Cutting and Pasting With the exception of specific recommendations made in the study, do not simply cut and paste whole sections of the original document into the executive summary.
You should paraphrase information from the longer document.
