For the second year in a row, Rometty is considered the most powerful woman in business as the CEO of IBM. The magazine has been tracking the most powerful women in business since 1998 when they began this list.

Pattie Sellers, the magazine's editor-at-large, said on "CBS This Morning" that one of the most interesting things about the women on Fortune's list is most of them didn't think about their careers as climbing up a ladder.

"The really interesting thing about these women leaders which we've been following for 15 years now, is that they tend not to think about their careers as ladders," she said. "They take a lot of lateral moves. They enhance their resumes by broadening their experience base because women have to operate a little bit differently to get ahead."

The magazine didn't just chose women based on their net worth or how many people they managed. Seller explained that they followed their definition of "power."

"We evaluate power, for purposes of this list, as the size and importance of the woman's business in the global economy, the health and direction of the business, the arc of the woman's career and social and cultural influence," said Seller.
