Hi,
I'm working currently on a project to decrease reccuring requests from customers with a VIP program and i want to be able to measure the decrease of requests.
I built a small excel file in order to fill in the average of requests before the beginning of the VIP follow-up (last month) and the number of requests by week 6 weeks after the beginning of the follow-up so i can see how much it decreased.
I entered false numbers in my file to see if i'm able to built a stacked bar chart where i can see week after week the overall or per customer difference between the number of average requests before and after the follow-up but for now i'm not getting anywhere.
Thank you for you help and advices
