Prime Minister Theresa May in Great Britain and CEO Marissa Mayer at Yahoo are two examples of women brought in to lead in extremely trying circumstances. It’s no more a coincidence that a country and company in turmoil both looked to women to lead than it is that a last-ditch “Hail Mary Pass” effort involves a prayer to a woman. But if companies and governments brought in women earlier, to both boards and leadership positions, they likely would do a much better job avoiding probable but neglected gray rhino crises. Waiting until it may be too late misses key opportunities to handle gray rhinos before they charge. Read my perspective at the Women’s Media Center.
