Having an explicit and coherent message in mind helps you organize your report.
Determine the main idea that you want to convey to your audience.
Write your overall report goal in one to three sentences. For example: “I want to show the daily progress metrics. Company employees will check this report multiple times a day to see how the team is doing.” This tip comes in handy when you begin your first draft of the report.
Break down your report goal into sub-goals or key points. This information determines your content. What message do you want to communicate on each page?
Identify the highlights. If your audience has limited time to look through your report, ensure they get the main message. Remember that your perspective might be different from the audience's.
Storytelling helps your audience learn and absorb new information. The story of your report is the communication of your primary objective and sub-goals.
Ensure that your report tells only a single story. Each page or section of a report should support the overall story and it should not communicate different messages.
Avoid overwhelming your audience with details. Consider linking to details through a hidden page or at the end of the report.
