The road to Tableau was an eye opening experience for me. Noah really nailed it, there is nothing I couldn't really do before Tableau, but it just is so fast to do an amazing visual analysis that allows me to see opportunities, that I am so much more effective.
There’s absolutely nothing that Tableau can do that I couldn’t do before, but that’s exactly the point: it lets me do the exact same stuff much faster, cutting down on the parts of my job that aren’t the most exciting and leaving more time for more valuable work. So far, the things I use Tableau for take less than half as long as doing them with my more familiar toolset, and I end up with the same results.
