I respectfully disagree. The amount of folks in upper management that can actually use something like Tableau is very small. However it doesn't matter as none of those people have the time outside of very small businesses which probably don't need it anyway. The business intelligence person is supposed to deliver succinct insights to upper management to act on, not say "here's a cool system I built you... figure it out yourself". Executives aren't getting paid $$$$$$$$ to do data analysis. Hopefully I'm not misrepresenting your point.
