A recent study featured in Harvard Business Review explores how more women can get to the top. The feature's author Evelyn Orr of the Korn Ferry Institute explains what interviewing 57 female CEOs unveiled about the gender gap.

"We were shocked to learn that two-thirds of the women we interviewed didn't view themselves as CEO material," says Evelyn Orr VP and COO at the Korn Ferry Institute. Orr explains ways companies can build women in the pipeline for the CEO level. "I think the key for companies is to identify high potential talent early," says Orr.

This week, Tina Smith was sworn in as a junior Senator for Minnesota, replacing Al Franken. This marks a record number of 22 senators. "It is showing slow and steady progress," says Orr. "It's important that we normalize female leadership."
