I think you miss the point. Maybe 5%* of users of Word actually know how to use it.
+1. That's another drum I've been banging for years.
Often though developers will use whatever icon they like the look of so it's not SAP who make it inconsistent.
This is true, however, it should be normalised before it goes into a production environment.
In a previous job, we were implementing a new back office system. I didn't have a lot of dealings with it personally (I'm not wholly sure what it was even, a glorified CRM I think). My lasting memory of it (other than the constant whining from the users) was that one of the primary toolbar buttons (for 'new call' or 'save' or some such) was an icon of Odie.
Yes, -that- Odie. No, me neither.
