If you're clear on what you believe, you have a great foundation to go make a market.

Big Data will spell the death of customer segmentation and force the marketer to understand each customer as an individual within eighteen months, or risk being left in the dust.

One of the most important things for any leader is to never let anyone else define who you are. And you define who you are. I never think of myself as being a woman CEO of this company. I think of myself as a steward of a great institution.

And so when I moved to IBM, I moved because I thought I could apply technology. I didn't actually have to do my engineer - I was an electrical engineer, but I could apply it. And that was when I changed. And when I got there, though, I have to say, at the time, I really never felt there was a constraint about being a woman. I really did not.

For CEOs today, it's all about acheieving growth and efficiency through innovation. It's not about product innovation so much anymore as about innovating business models. process, culture and management.

And the reason I came to IBM was I think - I always say at a really early age, I learned you've got to be passionate about what you do. No matter what it is, you put too much, your heart and soul in it, you have to be passionate about it. You make too many sacrifices.

We have started something called the Corporate Services Corps. Now, it was modeled after the Peace Corps from long ago, the 1960s. And the idea was in this modern day and age, how do you get IBM’ers around the world to be global citizens? You know, globally aware, contribute, understand how to work in that environment, but do it on scale.
