Features don't exist unless you know about them

Jensen Harris of Microsoft at "An Office User Interface Blog" tells the story of the missing drawing tools in Word and Excel:

again and again we hear stories about people assiduously creating drawings in PowerPoint and copying them over piece by piece into their Word or Excel document. I remember during a site visit watching a man create a simple flowchart in Excel which should have taken 3 minutes actually take 15 minutes because of all of the cross-application, clipboard, and windowing work it took to keep moving shapes between the apps.

Why do many people believe the drawing tools are only in PowerPoint? Quite simply, PowerPoint is the only application which shipped with the Drawing toolbar turned on by default.

This is an idea with broad impact for BI design: we need to make sure that users, especially casual users, see everything they need.
