Kelly Chambliss is the Chief Technology Officer and Strategy Leader of IBM's multi-billion consulting unit, Global Business Services.
She landed at IBM over a decade ago when it bought Pricewaterhouse-Coopers Consulting in 2002 and she worked her way up to a powerful role in the org, leading product management, engineering, and strategy.
But that alone is not what landed her on this list.
She is also hugely active in a program that mentors promising young women at the company, IBM's Network of Emerging Women (NEW) Leaders.
"A few years ago, I encouraged someone that I mentor to move into a role that was clearly outside her comfort zone," Chambliss told us. "Two years later, she was offered her ‘dream job’ within IBM – a role that would not have otherwise been available to her."
And she's a mentor for other leadership training programs as well.
In her college years, she attended Virgina Tech on an athletic athletic scholarship to play volleyball.
Now she's writing a book how girls who play team sports can learn a lot about business. "I believe we learn the most when we take risks and try new things without being constrained by the fear of failure," she tells us.
