I led the no-Excel policy in one of the biggest retail companies in Europe and I think that since we moved into structured Dashboards and daily granular data we became even faster in making decisions, but we also simplified the complexity of a problem
I see more and more organization using EXcel to analyze and process data, I think it's wrong, I also think setting a reporting system such as Tableau or Power BI is wrong without having clear borders. We became super obsessed with data, and on every stupid thing we ask for a dashboard or we extract a lot of data into an Excel sheet and start working with it, just to find out we done nothing to actually grow our user's experience.
If you using Excel, I will love to be convinced I am wrong!
