Feedback Wanted: How Effective Is My Service Delivery Workbook for KPI Reporting?

I have compiled a workbook based on the delivery of service; the results are reported via a summary page. If you have any thoughts or suggestions, I would be grateful for any feedback that you may have. Please feel free to download and use.

Best regards,
Peter

Thank you very much. Your Excel work is truly amazing. However, my biggest disappointment is that I couldn't use this format properly. Could you please help me learn how to work with Excel as effectively as you do?

Best regards,
