How can CIOs do this?

You have to really understand how to change your business processes. You really have to have somebody who understands your business processes. I find that it's the IT department, who sees all those things come together, that can help with that. Sometimes they're not engaged to reinvent the business.

As a CIO, what keeps you up at night? What do you worry about?

Cybersecurity. And I keep marching up the bar to make sure that we manage cybersecurity. [I worry about] the guys who are coming after you all the time. (Laughs) With hackers you want to make sure that they're not in your business, that they don't have access to your customers, that you're doing things to improve your products to make sure that you aren't vulnerable and that you keep your eye on the ball.
