I maintain an in-house developed 'enterprise database app'. When someone suggests new additions to this app, I tell him/her to use Excel to test their idea for a few weeks first, and then ask again. This gives a pretty good idea what they really want, because if people have to track stuff themselves they'll do only the barest minimum, and that's eventually what should go into the enterprise application.

That is exactly what I do and it has worked out pretty well. If they don't use the Excel sheet, then I know they wouldn't much care to use my ERP module either. Saves time and resources.
