Already stopped doing reports
Several years ago I convinced our team to not write special reports.
Instead, we wrote report engines that gave you all the data might possibly want in various sections (with date range and other criteria of course).
The output can come as a web page or as a spreadsheet.
If you want something different or special, mess with the spreadsheet.
The users love it and now we only have one or two extra-special reports we end up doing every year because of specific requirements for programs that actually bring money.
If you want to analyze stuff, you can do it on your own with access to data.
