I left Xerox for the non-profit sector because it was clear to me that only public/private partnerships can pull off a turnaround plan at the scale we need to tackle global poverty.

Entire families work for Xerox.

By the time I stepped down as Xerox's CEO in 2009 - and as chairman in January 2010 - Xerox had become the vibrant, profitable and revitalized company that it still is today. What made the difference was a strong turnaround plan, dedicated people and a firm commitment from company leaders.

Sustainable development is a proven catalyst for Xerox innovation.

Turnaround or growth, it's getting your people focused on the goal that is still the job of leadership.

When I became CEO of Xerox 10 years ago, the company's situation was dire. Debt was mounting, the stock sinking and bankers were calling. People urged me to declare bankruptcy, but I felt personally responsible for tens of thousands of employees.
