Steve Levitt, author of Freakonomics, gave a presentation on big data in corporations. It should be watched by all CEOs and wanna-be CEOs. It's discouraging in that it shows many companies' unwillingness to use the data they have, but it's encouraging. You don't need to be perfect to beat your competition, just have a willingness to make decisions with data, and spend a little in resources to make it happen. It's also a fun presentation with lots of chuckles.
