The above example of an executive summary format clearly breaks down the data illustrated by the marketing report.
Thus, each executive summary will differ slightly depending upon what the report is about.
The format of the executive summary is broken down by relevant points and is easy to read.
A person reading this executive summary can quickly determine whether to read the report, and can get an idea of the appropriate course of action- and the justifications for the recommendations- even without reading the entire report.
Thus, the example serves the precise function that an executive summary is designed to serve.
