The whole idea of this blog, it to make you aware that in any report you send to the customer there should be these 3 tabs in the excel, without which you will make the report less impactful. One more important thing it to include the name of the parameters in X & Y axis. The report should be easy to understand by its audience.
The key tabs, that are essential are
Tab 1. Methodology - this tab should have the assumption/hypothesis along with the step by step description of the steps that were taken to generate the report.
Tab 2. Findings -this excel tab should have the Findings and Inference of the report. A good suggestive graphs should be there to make the audience understand the reports.
Tab 3. Comparison - this tab should show the actual numbers that were used to generate the graphs.
I hope that these 3 tabs you will always include in your reports.
